Stan dard Fea tures of the Con cept 50x



 — The Concept 50x complies with the British

Insurance Industry’s Criteria for Vehicle Security as evaluated by
Thatcham, the Motor Insurance Repair Research Centre.


Lifetime Warranty

 — For as long as you own the vehicle, Clifford will

repair or replace the control unit and remote controls free of charge (see
warranty card for full details).


FACT — False 

Alarm Control and  Test

 — One of many patented Clifford

innovations, FACT absolutely, positively ends recurring false alarms. 


A Pair of 4-Button/12-Channel Remote Controls

 — For fingertip command

from a distance.


Anti-CodeGrabbing (ACG) with Random Code Encryption

— Today’s

criminals are shifting from code scanning to a new, much more efficient
method of electronic thievery: “code-grabbing.” When you use a car
alarm remote control, it transmits a digital code to your alarm. A thief
with a code-grabber can record that code right off the air from hundreds
of metres away, then play it back when you’re gone to disarm the alarm
and unlock the doors. Within seconds, your car is just another theft
statistic. Fortunately, Clifford’s Anti-CodeGrabbing (ACG) randomly
changes the transmitted code every time you press any of the remote
control buttons. And since these codes are selected by the system’s
microprocessor from an electronic file containing several trillion codes,
the remote control 


 sends the same code twice, and the system

control unit 


 accepts the same code twice. That makes

code-grabbing utterly useless against the Clifford Concept 50x.


Built-In Two-Point AutoImmobiliser

 — For the utmost in theft prevention,

two AutoImmobilisation circuits interrupt both the starter and
ignition/fuel pump whilst the system is armed. Even if a thief were to pull 
the fuses or cut all the wires, the starter and ignition/fuel pump remain


Failure- Proof Driv ing Safety

— Even in the unlikely event of a system

malfunction, the AutoImmobiliser will not stop the engine whilst the vehicle
is being driven.



background image

Stan dard Fea tures of the Con cept 50x 



UltraSecure Coded Valet Mode

 — Requires a code that you may select to put

the system in valet mode or program in an additional remote. This ensures
that no thief can turn off your Concept 50x as they can with other alarms.


Re mote Con trolled Valet Mode En try and Exit

— With just a press of a button on 

your remote control, you can enter or exit valet mode. Indicator light flashes
visually confirm valet mode entry and exit.


Dual-Zone Proximity Sensor

— Two sensor zones provide full protection: If 

someone is lurking near your car, the system will sound a warning tone.
But if a thief actually leans into the passenger compartment, the system
will instantly blast the siren. It is impervious to wind and temperature
variations that cause ultrasonic sensors to false alarm.


Glass Tampering Sensor

 — Can detect attempts to break any of the

vehicle’s windows. An optional second microphone is available for larger
vehicles, such as estate vehicles.


Dual-Mode “Chirp” Silencing

 —Whenever you wish, you may press a

button on the remote control to arm or disarm the system silently. It’s
perfect when parking at night in a quiet residential area. Or, if you prefer,
you may turn off the chirps on a long-term basis until you wish to turn
them back on.


Remote Door Locking/Unlocking with Built-in Relays


 No more fumbling

with keys in the dark or bad weather! A single press of a button on the
remote control simultaneously arms your system and locks the doors.
Another press disarms and unlocks. 


User- Selectable AutoLock

— Automatically locks the doors the instant you turn 

on the ignition to start the engine.


User- Selectable Aut oUn Lock

— Unlocks when you turn off the engine.


Smart Self-Powered Siren with Unbreachable Digital ComLink



Continuous two-way digital communication between the system and the
siren assures that if, at any time, the system fuse is pulled or any siren
wire is cut, the siren will instantly activate for five minutes. Yet when the
system is disarmed and power is interrupted, the siren will remain silent.


Auto matic Low Bat tery Warn ing:

 If the siren’s back-up battery voltage is low,

the normal arm and disarm chirps will be muted to alert you of the problem.
Once recharged, the chirps will automatically be restored.



background image

Stan dard Fea tures of the Con cept 50x 



Smart Remote Boot Release Capability

 — Assures that the optional remote

boot release can be activated only if the system is in its disarmed state, thus
avoiding the possibility of falsely triggering the system. This feature also
ensures that the boot release cannot be remotely activated whilst driving.


Remote Window/Sunroof Closure Capability

 — On certain vehicles

(including several models of Mercedes Benz, Jaguar, Volkswagen, Audi
and BMW), the integrated timer and an optional relay can be used to
automatically close the power windows and sunroof every time you
remotely arm.



— Whenever you desire, you may choose to lower the decibel

volume of the arm and disarm chirps to a level that is clearly audible but less
obtrusive than the full-volume chirps. All it takes is a few flicks of a switch.


User-Selectable AutoArming

— Automatically arms itself “passively” if

you forget and has all these additional features:


AutoArming En able/Dis able

— You may disable or re-enable the AutoArming

feature with just a few flicks of a switch.


AutoArm & Lock

— You may set the system to automatically lock the doors

every time the system AutoArms.


Vis ual In di ca tion

— Two indicator light flashes signal that the 30-second

countdown to AutoArming has started.


In stant AutoArm By pass

— Just a quick turn of the ignition switch will bypass

AutoArming for one cycle — perfect when fueling the vehicle. AutoArming
is automatically restored the next time you park.


Patented Smart Prior Intrusion Attempt Alert

 — When you return to your

vehicle and remotely disarm, a special chirp and indicator light flash
sequence will audibly and visually alert you if an intrusion attempt was
foiled whilst you were away. Your Concept 50x will even identify the
specific trigger or sensor that detected the intrusion attempt.


Remote Controlled Courtesy Lighting

 — For your personal safety and

convenience, when you remotely disarm your Concept 50x, the interior lights
turn on and stay on until you start the engine or 30 seconds, whichever
occurs first.



background image

Stan dard Fea tures of the Con cept 50x 



Built-In Indicator Light Flasher

 — On-board relay and circuitry will visually 

confirm door lock and system status.


Patented Smart AutoTesting

— Automatically tests all system triggers and

sensors every time you remotely arm and warns you if you accidentally
arm your Concept 50x system with the bonnet or boot open. If there is a
genuine trigger or sensor malfunction, the system will specifically
identify the problem, thereby eliminating time-consuming and costly


Patented Malfunction AutoBypass with Automatic Monitoring

 — In the

unlikely event of a trigger or sensor malfunction, Concept 50x
automatically bypasses the malfunction and arms all other points to
continue relentless protection of your vehicle. If you simply left the
bonnet, boot or a door open when you armed, just close it and the system
will again monitor that trigger point.


Multiple-Event TotalRecall

— Concept 50x’s memory stores the identity of

the last eight trigger and sensor activations. This provides an invaluable
diagnostic means, since, whenever you wish, the system will visually
identify the activated triggers and sensors in reverse chronological order.


Patented Remote Control Code Learning with MultiRemote Recognition


Just a few flicks of a switch lets you match to the system up to 4 different
12-channel Clifford ACG remote controls. Just as easily, a lost or stolen
remote control can be deleted.


Multiple-Car Control

 — You may use the same remote to control Concept

50x systems on up to six of your other vehicles.


High-Luminescence LED Status Indicator

 — Adds visual deterrence and

identifies system status.


Patented SmartPowerUp II

 — When power to the system is disconnected,

the system’s nonvolatile memory always remembers the security system’s 
last state (armed or disarmed) and returns to that state when power is
restored. So if a thief disconnects the power and then restores it in an
attempt to start the car, the system will instantly re-arm.

Your 4-button/12-channel remote controls

The 4-button/12-channel remote controls are ultra-sophisticated miniature radio
transmitters powered by a tiny 12-volt battery. A weak remote control battery will
reduce range (see page 18 for battery replacement instructions). Electrical interference
and even sunspots can interrupt the signal from your remote control to the system. If 
this happens, repeatedly press the remote control button (this is more effective than
holding the button). The 4-button/12-channel remote control is the key to your
system. It has Clifford’s Anti-CodeGrabbing (ACG) technology for the ultimate
protection against “code-grabbing” devices (see page 8). You will use your remote
to arm and disarm the system, lock and unlock the doors, engage and disengage the
AutoImmobilisation circuits, enable/exit valet mode and command options such as a 
remote boot release, power window operation and even remote engine starting.

How to use your key chain re mote con trol

Your remote control can individually
command up to 12 different system functions
and options. It’s like having a TV with 12
channels. You change channels (functions)
with your keychain remote control. But
instead of putting 12 buttons on the remote,
we made it easy: First, the button you use
the most — button 1 to arm, disarm, lock and 
unlock — is larger than the others. Buttons 2,
3 and 4 are the smaller buttons to the right,
below and left of button 1. The LevelShift
button on the side of the remote control allows you to select channels 5–12:


To trans mit ei ther chan nel 1, 2, 3 or 4:

Just press either button 1, 2, 3 or 4. For

instance, to transmit channel 3, press button 3. whilst you transmit, the LED
indicator will blink once every second: this indicates level 1.


To trans mit ei ther chan nel 5, 6, 7 or 8:

Press the LevelShift button once. This

shifts buttons 1–4 to level 2 (channels 5–8). Then press the desired button within
the next 7 seconds
. For instance, to transmit channel 5, press the LevelShift button 
once, then press button 1. whilst you transmit, you’ll notice that the LED indicator 
blinks twice, pauses, blinks twice, etc.: this indicates level 2.


To trans mit chan nel 9, 10, 11 or 12:

Press the LevelShift button twice. This shifts 

buttons 1–4 to level 3 (channels 9–12). Then press the corresponding button within 
the next 7 seconds. For instance, to transmit channel 10, press the LevelShift button
twice, then press button 2. whilst you transmit, you’ll notice that the LED blinks
three times, pauses, blinks three times, etc.: this indicates level 3.

NOTE: One second after you stop transmitting level 2 or level 3 (channels 5–12),
the remote control automatically returns to level 1 (channels 1–4).

What each button/channel does

Your Concept 50x remote controls come preprogrammed so that certain channels
command certain functions. The following chart indicates what each remote control

AC CES SORY. . . . . . .

Button 2 (channel 2) controls an electronic interlock that lets you
separately command two functions with the same channel: one
when the system is armed, another when disarmed. 
button 2 whilst the alarm is armed will activate the system’s
timed output for any duration you wish between one second and
two minutes (the factory setting is 30 seconds; see
User-selectable features on pages 16-20).


Button 2 (channel 2) can control another function when the system
is disarmed, such as an optional remote boot release. Pressing
button 2 whilst the alarm is disarmed will remotely open the boot.

ALARM STATE . . . . . . .

Button 4 (channel 4) and channels 5–9 and 10–12 (see How to use 
your keychain remote control
 on page 6) can activate accessories
such as the IntelliStart remote engine starter, remote power
window control, ACG Garage Door Opener Interface, Concept
50x systems and accessories on your other vehicles, etc.

CHAN NEL 9? . . . . . . . .

Channel 9 is used to remotely enable or exit valet mode. See page 
11 for more information.

Anti-CodeGrabbing (ACG) with Random Code Encryption

Protects you and your automobile from the most effective and onerous car stealing
device ever used by car thieves — a code-grabber. Code-grabbers literally record,
from hundreds of metres away, the code sent by your car alarm remote control.
Then the thief simply plays back the code when you’re gone, instantly disarming the 
alarm and unlocking the doors. It’s like giving the thief your car keys. But not if you 
have the Concept 50x, since it utilises complex digital signal processing and
unbreachable encryption to randomly change the digital code every time you use the 
remote control. Your remote control will never transmit the same code twice, and
the control unit will never accept the same code twice. Thus the code recorded and
played back by the thief’s code-grabber will never be accepted by your Concept 50x.

Smart prior intrusion attempt alert

If you hear three chirps when you remotely disarm instead of the usual one chirp, it
means that a trigger or sensor was activated in your absence. When you enter the
vehicle and turn on the ignition (or start the engine), the LED will blink 1–6 times,
pause, then repeat the blink cycle 4 more times. Count the number of blinks in one
cycle and refer to the chart on page 14 to identify the trigger or sensor that was
activated whilst you were away.

How to interpret the chirps and indicator light flashes

When you use the remote, the system responds with chirps and indicator light flashes:

Chirps and flashes



Your system is disarmed


Your system is armed

2 and then 4

Armed but there is a door open or the sensor is malfunctioning

(see Smart AutoTesting on page 14)


Disarmed but there was an intrusion attempt whilst you were away

(see Smart prior intrusion attempt on page 8)


Armed but the bonnet or boot is ajar (see Smart AutoTesting on page 14)

How to interpret the LED status indicator

The LED on your car’s dashboard or console will inform you of the system status:

LED Condition



System is disarmed and in normal operating mode


Valet or programming mode.


The AutoImmobiliser is engaged and/or the system is armed and protecting your vehicle

Pause between flashes

Either a malfunction (see page 14) or an intrusion was attempted (see page 8)


If  you forget to remotely arm, the system will automatically arm itself 30 seconds
after you park the vehicle, exit, and close all the doors. For your convenience, if you 
re-open any door(s) within the 30-second countdown, AutoArming will restart from
the beginning once all doors are closed. Concept 50x has these additional
AutoArming features:


AutoArming en able/dis able:

If you prefer, you may deactivate or reactivate

the AutoArming feature. See User-selectable features 

on pages 16-20.


Vis ual ac knowl edg ment: 

Five seconds after you exit the vehicle and close all

the doors, the indicator lights will flash twice to confirm that the AutoArming
countdown is progressing. Then, 25 seconds later, the system will AutoArm.


AutoArm & Lock:

To ensure you can’t accidentally lock your keys inside the

car, the system is factory-set not to lock the doors upon AutoArming. To
change this setting, see

Prevents AutoArming when fuelling and other

times when you wish to temporarily bypass AutoArming. To activate Instant
AutoArming Bypass, rapidly turn the ignition switch to “ON” then “OFF.” You
will hear a single siren chirp to confirm that the system will not AutoArm. The
system reverts to its normal operating mode when you next start the engine.

Ul traSe cure Coded Valet Mode

Your se cret valet code

NOTE: If you tem po rar ily lose the use of your re mote con trols, you can dis arm the
sys tem by ena bling valet mode.

All car alarms have a valet mode that turns off the security features. This mode is also used
to turn off the alarm if it  is not responding to the remote. However, thieves can disable other
alarms in seconds by hotwiring the ignition and flicking the alarm’s easy-to-find “hidden”
valet switch. In contrast, your system has safeguards to ensure a thief cannot enable the
valet mode as a way of “turning off” your system. How? To enable valet mode, the driver
must enter a secret valet code on the PlainView switch. 

Your factory preset code is

noted on the inside front cover of this manual. You may, whenever you wish, change
the code to one of your own choosing. In valet mode, the system’s AutoArming feature
(see page 9) and all the security features are turned off. At various times, you will need to
switch the system off, such as when washing your car.

Your factory- set valet code is noted on the in side front cover of this man ual. As
such, you should NOT keep this man ual in your ve hi cle, since it could be dis cov 


ered by a thief.




A digit is defined as any number from 0 to 9, inclusive.


Valet code:

Your valet code is the factory preset 4-digit number noted on the

inside front cover of this manual, or one that you have chosen and programmed.


Plain View switch:

A rocker switch mounted on the dashboard or console. The

switch has three positions: 1.) Latched  2.) Centre  3.) Spring-loaded momentary.
When you press the latched side, the switch remains in its pressed position. When
you press the momentary side, the switch bounces back to the centre position.


En ter ing a digit:

To enter a digit, you tap (press and release) on the momentary

side of the PlainView switch the number of times corresponding to the numeral of 
the digit to be entered, followed by pressing to the latched side, then returning the
switch to its centre position.


En ter ing a code:

To enter your 4-digit code, just repeat the above for each digit

of your code. If the digit is a zero, you will simply move the switch to its center
position, then to the latched side as noted in the following example:

EX AM PLE: To en ter a code of 1203, you would move the
switch thusly: Mo men tary, latched, mo men tary, mo men 


tary, latched, cen tre, latched, mo men tary, mo men tary,
mo men tary, latched, cen ter.

NOTE: You may NOT se lect a code that be gins with a zero. The first digit of your
code must be 1–9.



background image

To en able valet mode

1. Turn the ignition switch to its “ON” position or start the engine.
2. Enter your valet code on the PlainView switch, then return the switch to its centre position.
3. You now have 5 seconds to press the latched position to enter valet mode. The

system’s LED will glow continually for ongoing visual confirmation of valet mode.

To exit valet mode

The system will automatically exit valet mode the next time that the ignition switch is
turned to the “ON” position (e.g., when the engine is started).

Be sure to re turn the Plain View switch to its cen tre (neu tral) po si tion. Oth er wise,
the sys tem will auto mati cally in voke the To tal Re call fea ture (see page 14).

Setting your own secret valet code 

If you wish to set your own valet code, you may choose any 4-digit code, except one that
begins with a zero (e.g., 3210 is fine, but 0123 will not be accepted). You can also change
your valet code whenever you want. Simply write down the 4-digit code you wish to use,
then refer to the example below and the User-selectable features section on pages 16-20.

Ex am ple

Let’s say you want to set a valet code of 2301. To do so, you would do the following:
1. From the Table of user-selectable features on pages 19 and 20, you would note that

the “set a new secret valet code” feature is in column 3, row 6.

2. Enter program mode by turning on the ignition, entering your current valet code, then 

pressing the PlainView switch to its momentary side for 3 seconds until you hear a chirp.

3. Select column 3 by moving the switch between latched and centre 3 times, i.e.:

latched, centre, latched, centre, latched, centre. After a brief pause, you will hear 3
chirps to confirm that you have selected feature column 3.

4. Select row 6 by pressing and releasing the momentary side of the switch 6 times. To

help you count, you will hear a chirp each time you press the momentary side. Then
immediately flip the switch to the latched position.

5. Immediately enter your new code. To enter 2301 as your new code, you would press the

switch in this manner: momentary, momentary, latched, (you’ll hear 2 chirps to confirm
the first digit), momentary, momentary, momentary, latched, (3 chirps to confirm the
second digit), centre, latched (zero chirps), momentary, latched (1 chirp), centre.

6. Wait 3 seconds until you hear 2 chirps, indicating the new code has been accepted.
7. Turn off the ignition to exit program mode (you’ll hear a 3-chirp confirmation).
8. VERY IMPORTANT: You must now test your new secret valet code: Turn on

the ignition, enter your new code, then flip the switch to its latched position. The LED 
will illuminate. If it does not, the new code you programmed and the one you just entered 
do not match. In such a case, the system will revert to the previous code.

Remote controlled valet mode entry and exit

You can even remotely enable or exit valet mode by transmitting channel 9 (LevelShift
twice, then button 1). In addition to the above indications, two indicator light flashes
confirm remote enabling of valet mode, a single flash confirms exiting. The next time
that the ignition switch is turned to the “ON” position, valet mode is automatically exited.



background image

Keyless entry in valet mode

Even if valet mode is enabled, you can still remotely control the convenience features.
For instance, press button 1 (channel 1) as if you were disarming: the doors will unlock
(confirmed by one indicator light flash) and the interior lights will turn on. Press
button 1 again and the doors lock (confirmed by two flashes). You can also use the
other channels to activate options such as a remote boot release or remote engine starting.

Sensor adjustment

The two zones of your Concept 50x’s Proximity Sensor provides dual-level protection
of your vehicle. If someone is lurking near your car, perhaps bringing their hands and
face to the window to see what is inside, the outer zone of the sensor will pick up this
nearby movement and trigger your Concept 50x to issue its warning tone. But if a thief
actually leans into the passenger compartment, the sensor’s interior zone will be
triggered and the system will instantly blast the full alarm sound. The Clifford
Electronics Proximity Sensor is a radar-type sensor that uses a more sophisticated, more
accurate and more reliable technology than that of ultrasonic-type movement sensors.
As such, the Dual-Zone Proximity Sensor of your Concept 50x is impervious to normal
environmental conditions such as wind and temperature variations that cause
ultrasonic sensors to false alarm.

Your Authorised Clifford Dealer will have adjusted each of the two sensor zones at
the time of installation. If you find that the sensitivity setting of one or both appears
to be a bit off the mark, any local Authorised Clifford Dealer will be happy to make
any necessary readjustments without charge.

Remote controlled override of one or both sensor zones

Transmitting channel 10 (two presses of the side LevelShift button, then a press of
button 2) within 10 seconds of arming the system will override the exterior warning
zone of the Dual-Zone Proximity Sensor. When you do so, you will see 4 indicator
light flashes to confirm the zone override. This is useful when parking in an area
with heavy pedestrian traffic. Transmitting channel 10 again within the 10 second
period will override both zones of the sensor for those times when you must leave a
passenger or pet in the vehicle. The sensor zones are automatically restored the next 
time you arm the system.

AutoLock and AutoUnLock

For your safety and that of your passengers, the doors automatically lock the instant
you turn on the ignition (see User-selectable features on pages 16-20). When you
turn the ignition off, AutoUnLock automatically unlocks the doors. To suit your
preferences, you may turn off either or both the AutoLock and/or AutoUnLock

Built-In Two-Point AutoImmobiliser

Thirty seconds after you turn off the ignition, the system’s built-in two-point
AutoImmobiliser electronically disengages your vehicle’s starter motor and
electronic fuel pump to ensure against theft of your vehicle. The LED Status
Indicator will repeatedly flash to indicate that AutoImmobilisation has been
activated. Even if a thief were to cut all the wires or even find the Concept 50x
control unit and disconnect it, he would still be unable to start the engine.

Please be aware that, un like AutoArming de scribed above, Auto Im mo bi li sa 


tion oc curs re gard less of whether you open or close any doors. What’s more,
dis abling the AutoArming fea ture has no ef fect on Auto Im mo bi li sa tion.

When you remotely disarm your Concept 50x, the AutoImmobilisation circuits
automatically disengage. You then have 30 seconds to start the engine (or turn the
ignition switch to its “ON” position). If more than 30 seconds pass, the immobiliser
will automatically reactivate. This will be visually indicated by the LED repeatedly

To dis arm the Auto Im mo bi liser, use the re mote con trol to arm and then dis arm
the sys tem.

Train/Draw bridge Fea ture

Your Concept 50x has a new feature to make restarting the vehicle easier and safer
after stopping for a passing train or a raised drawbridge. You may need to shut
down your vehicle’s engine when waiting. But, after 30 seconds, the immobilisation
electronics of your Concept 50x will engage, which will prevent engine starting. To
clear this immobilisation and to start the engine after this occurs, simply do the

1. Turn your ignition switch to the “ON” position.
2. Press button 1 on your remote control. This will both disengage the immobilisation

and will automatically lock your vehicle’s doors to ensure driving safety.

3. You may now start the engine.

False Alarm Prevention and FACT — False Alarm Control and Test

False alarms are usually caused by a car alarm’s sensor that either cannot detect the
difference between normal environmental conditions and a genuine theft attempt or, 
in the case of your Concept 50x, has its sensor sensitivity set too high (this can be
readjusted by any Authorised Clifford Dealer). Clifford’s exclusive FACT feature
ensures you’ll never experience repeated false alarms. If the siren goes off, DO
NOT remotely disarm; allow it to run for the full 30-second siren duration. Before
sounding the siren a second time, the system automatically checks for another
activated trigger or sensor to verify that a genuine intrusion is in progress. Should
the siren sound again, you will know for sure that someone is tampering with your
vehicle. (To disable FACT, see User-selectable features on pages 16-20.)

Smart AutoTesting

Each time you remotely arm the system, it tests all triggers and sensors. If the bonnet
or boot
 is open, the system will immediately alert you with 4 chirps and 4 indicator
light flashes
 instead of the usual 2 and 2. If a door is ajar, you will receive the usual 
2 chirps and 2 flashes, then, 5 seconds later4 chirps and 4 flashes. (The door ajar
warning will not work on vehicles with factory-delayed or dimming courtesy lights). If
sensor is malfunctioning, you will receive the usual 2 chirps and 2 flashes, then,
10 seconds later, there will be 4 chirps and 4 flashes. 


Spe cific mal func tion iden ti fi ca tion:

If you get the 4-chirp/4-flash signal upon

arming, perform the following to identify the malfunctioning trigger or sensor:

1. Remotely disarm, then turn on the ignition. The LED status indicator inside your

vehicle will be flashing, pause, then repeat.   

2. Count the number of blinks in one cycle between pauses (for your convenience, the

blink cycle repeats a total of 5 times) and refer to the chart below:

Number of LED blinks between pauses

Trigger/sensor indication

1 blink

Proximity Sensor

3 blinks

Glass Tampering Sensor

4 blinks*

Door trigger*

5 blinks

Boot trigger

6 blinks

Bonnet trigger

7 blinks

Three incorrect consecutive valet code entries were made

* If your ve hi cle has in te rior light de lay or dimming, the sys tem can not pro vide this in di ca tion.

Automatic malfunction bypass

The system will automatically bypass any faulty point and arm all other triggers and 
sensors to provide the utmost possible protection until you can have the system
serviced by your local Authorised Clifford Dealer. If you armed with the bonnet,
boot or a door open, just close the open point and the system will again monitor that 

Multiple-event TotalRecall

The system’s memory records the identity of the last 8 activated or malfunctioning
triggers and sensors, which allows your installer to track down any malfunction. To
identify the triggers and sensors held in memory, use the following procedure:

1. With the ignition OFF, flick the PlainView switch to its latched side.
2. Press button 1 to “arm” the system, then again to “disarm.”
3. The LED will blink 1–6 times to indicate the most recently activated point, pause,

blink 1-5 times to indicated the next most recently activated point, and so on.

4. Write down the number of blinks between pauses and refer to the chart above.

SmartPowerUp II

If power is removed, SmartPowerUp II ensures the system will automatically restore 
itself to its previous state when power is restored. So if a thief disconnects the power
whilst the system is armed and then restores it in an attempt to start the car, the
system will re-arm and instantly sound the siren whilst immobilising the vehicle.

Smart Self-Powered Siren with Unbreachable Digital ComLink

This siren has its own built-in back-up battery, so even if a thief cuts all the wires,
the siren will continue to wail. Furthermore, this unique Clifford-designed and
manufactured siren has all these important additional enhancements:

Un breach able Digi tal Com Link:

Clifford’s ingenious Digital ComLink is a

serial communications link that ensures that — if the system fuse is pulled, or if
power to the system is interrupted, or if any siren wire is tampered with whilst the
system is armed — the siren will instantly activate for five minutes. However, if
the system is disarmed and power is interrupted for authorised servicing, the siren
will remain silent. This eliminates the need for a special separate shutoff key
common to other battery-backed sirens. This ingenious Clifford feature guards
against any possibility of a thief tampering with the system.

Smart- charging:

Other battery-backed sirens continually draw charging

current from your vehicle’s battery. In time, this can drain the car’s battery.
Clifford’s Smart Self-Powered Siren only draws charging current whilst the
vehicle’s ignition is on, i.e., whilst you’re driving. This prevents battery drain.

Long- term chirp si lenc ing:

Whenever you wish, you may silence your

Concept 50x’s arm/disarm chirps until you wish to restore them. The indicator 
light flashes will continue to provide visual confirmation of remote controlled
arming and disarming. See the User-selectable features section on pages 16-20.

Re mote con trolled chirp mut ing:

This is especially valuable when parking

late at night in a quiet residential area. To arm or disarm silently,  press button 
3 on your remote control instead of the usual button 1.

Qui etChirps:

You can control the volume of the arm and disarm chirps. As

shipped from the factory, your system issues full-volume chirp acknowledgments.
If you prefer, you may reduce the chirp volume to a level that is clearly audible,
yet less obtrusive. See the User-selectable features section on pages 16-20.

Auto matic low bat tery warn ing:

If at any time the siren’s back-up battery

voltage is low or it fails to hold its charge, the normal arm and disarm chirps
will be automatically muted to alert you of the problem. Once the back-up
battery is charged, the chirps will automatically be restored.

Noise Abate ment Cir cuitry:

Automatically limits siren sounding to 2.5

minutes even if a door is left open in the wake of an intrusion attempt.

User- selectable fea tures

Your Concept 50x allows you to set many of its features to your own personal
preferences via a few flicks of the PlainView switch. Once you’ve changed a few settings,
you’ll find that programming Concept 50x is so easy that you can even do it whilst
driving! The system comes with all of its features preprogrammed as noted by the bold
type in the Table of user-selectable features on pages 19-20. To change any of the
settings, use the steps noted below. To restore the feature to its factory setting, just
repeat the procedure:

How to change a user- selectable fea ture:

Briefly, here’s how it will work:

Pick a feature from the Table on pages 19-20, noting its column and row numbers.

First you’ll need to get into program mode by entering your secret valet code (see
page 10). After you have entered your code, press and hold the momentary side of 
the PlainView switch until you hear a chirp. You’re now in the “Feature Select”

Next you’ll press the latched side of the switch a number of times identical to the
column number. Lastly, you will press the momentary side of the switch a number 
of times corresponding to the row number.

That’s all there is to it! After you enter the feature’s column and row numbers,
you’ll hear either one chirp to indicate that the feature has been turned off, or two
 if turned on. It’s easy once you’ve done it. Try the examples on page 17.

Step-by-step programming instructions

1. Refer to the Table of user-selectable features and make note of the column (across)

number and the row (down) number of the feature(s) you wish to program.

2. Turn on the ignition, or start the engine (skip this step if the engine is running).
3. Enter your valet code (see page 10), then press the PlainView switch to its momentary

side for 3 seconds until you hear a siren chirp (the system LED will also turn on to
indicate program mode.) You are now in the “Feature Select” position.

4. Select the feature column: Toggle the switch in and out of the latched position the

same number of times as the column number of the selected feature (NOTE: each
latched-to-centre motion is counted as one). Pause. You will hear the same number of 
chirps as the column number you have selected, audibly confirming your selection.

5. Select the feature row: Press and release the momentary side the same number of

times as the feature’s row number. You’ll will hear a chirp each time you press.

6. If there is a 



for the selected feature, perform the actions noted.

7. Pause. You will hear either one or two chirps: Two chirps = ON, one chirp = OFF.
8. You may select another feature, or you may exit program mode:

a. To select another feature in that column, repeat step 5 within the next 10 seconds

(after 10 seconds, 3 chirps mean you are now back in the 

“Feature Select” position).

b. To select a different feature column, go to step 4.
c. To exit program mode, turn the ignition off (you’ll hear 3 chirps and the LED will

turn off). If driving, just wait 60 seconds for the system to automatically exit
program mode.

 Turn on AutoArm & Lock

When the system AutoArms (see page 9), it does not normally lock the doors to ensure
that you cannot accidentally lock the keys inside the vehicle. To enable this feature,
you’ll note that “AutoArm & Lock” is in column 3, row 2 of the table on pages 19-20.
The “


” in bold type indicates the factory setting. The following example will turn on

AutoArm & Lock.

1. To enter program mode, turn on the ignition, enter your valet code (as noted on page

10), then hold the switch in its momentary position until you hear a chirp.

2. Select column 3 by pressing the latched side and then returning the switch to its

centre position three times, then wait for the three chirps to confirm column 3. To
select row 2, press momentary two times (you’ll hear a chirp each time you press
the momentary side).

3. After a brief pause, you’ll hear two chirps to confirm that AutoArm & Lock is

now on.

4. Turn the ignition off. You’ll hear 3 chirps, confirming automatic exit from the

program mode, and you’re done!

If you make an error, just turn off the ignition and start again. To turn AutoArm &
Lock back off, just repeat steps 1–4. In step 3, you’ll hear one chirps to confirm that
the feature has been turned back off. Remember, one chirp = off, two chirps = on.


You have 10 seconds to enter the row number after selecting the column. If you 


too long, the system jumps back to the “Feature Select” position (this is indicated with 3
chirps). If you wait another 60 seconds, the system will exit program mode (this allows you 
to make programming changes even whilst you’re driving). In Example 2 below, you’ll
learn how easy it is to change the settings of several different features in just one
session, without having to repeatedly turn the ignition on and off:

EX AM PLE 2: Turn off AutoLock and Aut oUn Lock, then turn on Qui etChirps:

This time, we will change the settings of three different features in just one programming
session: We will turn off both the AutoLock and AutoUnLock features (see page 12), as
well as turn on the QuietChirps feature (see page 15). Here’s all you have to do:

1. Enter program mode as previously noted (ignition on, enter your valet code, then

press the momentary side until you here a chirp).

2. Since AutoLock is in column 2, row 1 of the Table, you will have to enter the

latched side twice and the momentary side once. Therefore, move the switch to
latched, centre, latched, centre. Wait for the two chirps to confirm the selection of
column 2. Within 10 seconds, press and release the momentary side of the switch
once (you will hear a chirp when you press it). After a brief pause, you’ll hear 1
chirp to confirm that AutoLock is now off.

3. Since AutoUnLock is in column 2, row 2 and is in the same column as you just

entered for AutoLock, there is no need in this case to again select column 2.
Therefore, you can go right away to the row selection (momentary side of the switch).
Now, within 10 seconds, press the momentary side two times to jump to row 2.
After a brief pause, you’ll hear 1 chirp to confirm that AutoUnLock is now off.

4. Note that the QuietChirps feature is in the same column 2, row 5. Simply press the 

momentary side 5 times.. After a brief pause, you’ll hear two chirps to confirm that
the QuietChirps feature is now on.

5. To exit the program mode, turn the ignition off. You’ll hear 3 chirps to confirm

program mode exit.


con tin ued . . .


background image

Notice that you did not have to reselect column 2. If you don’t touch the switch, the
system stays in the column for 10 seconds to allow you to select any other feature(s) 
in the same column without having to re-enter the column number. Of course, you
may also toggle the latched side to select a new column. If you wait more than 10
seconds, the system automatically jumps back to the “Feature Select” position.
This is the “standby” position: ready for entry of a new programming selection. If
no action is taken for the next 60 seconds, the system automatically exits program
mode, perfect if you program whilst driving or if you forget to turn off the ignition.

Changing the remote control battery

Your remote control is powered by a small 12-volt battery. As the battery begins to
go flat, range will decrease. Replacement batteries are available at all Authorised
Clifford Dealers and at most other electronics and automotive security shops. To
replace the battery (any Clifford Dealer will be happy to do this for you):

1. Remove the retaining screw and gently pry apart the two halves of the case with your 

fingernails near the bottom of the remote (where the keyring is).

2. Note the orientation of the old battery, then replace it with the new battery (+ and –

symbols are also engraved inside the bottom half of the case).

3. Snap the case back together by first aligning the top (where the LED window is),

then retightening (but not over-tightening) the retaining screw.

Adding new remote controls

For other drivers in your family, or if you wish to control Concept 50x systems on
your other cars with the same remote control, you can buy additional remote
controls from any Clifford Dealer (call our UK office on ring on 0800-929949 or
0181-646-8440 for the nearest dealers) and program them into the system yourself.
Each Concept 50x will respond to as many as four 12-channel ACG remote
controls. To add a new remote control to the system, use the procedures noted in the 
User-selectable features section on pages 16-20.

How to erase the codes of lost or stolen remote controls

If one of your remote controls is ever lost or stolen, you may erase it from the system
memory to make sure the missing remote control can never be used to disarm your
system. To do so, use the “Erase all channels” feature (column 1, row 5) on the
Table of user-selectable features on pages 19-20). This will clear all remote controls 
from the system memory. Then simply program each remaining and/or replacement
remote control as noted in the Adding new remote controls section above.
