Installation  

Where to Mount Your Unit

You will get optimum performance from your detector if you 

Mount

it at a

point approximately in the center of the vehicle, as low as possible on the
front windshield without obstructing the unit’s view of the road either to 
the front or rear. Make sure unit is level with the road. You can also mount 
it directly on the dashboard. 

The unit’s lens must not be blocked and the LaserEye should have a clear view
out the back window to allow 360° detection.

Radar and laser signals pass through glass but not through other materials
and objects. Objects that can block or weaken incoming signals include: 

Windshield wiper blades

Mirrored sun screens

Dark tinting at the top of the windshield

Heated windshields currently available on some vehicles 
(Instaclear for Ford, Electriclear for GM.) Consult your dealer 
to see if you have this option.

1.

Attach the rubber 
cups to the bracket.

2.

Make sure the rubber cups and your windshield are clean.

3.

Push the bracket firmly
onto the windshield.

4.

Attach the detector to 
the bracket. Check the 
angle of the unit.

5.

To adjust the angle if
necessary, gently push or
pull on the bracket to bend
it. DO NOT use the detector
to bend the bracket.

6.

Highway/City Mode

Setting your detector to 

City

mode delays all X band audio alerts until 

the signal strength reaches Level 3. (A single beep will sound when the 
signal is first detected.) This will reduce false alerts while you are driving 
in, or near, urban areas where there are many sources for conflicting 
X band signals such as microwave towers and automatic door openers.

Muting an Alert

Your detector allows you to quickly turn Off an audio 

Alert

by momentarily

pressing the 

Mute

button. If you press the 

Mute

button a second time 

during the 

Alert

, the audio 

Alert

will be turned back on.

Auto Mute

will automatically reduce the audio volume of all alerts 

after four seconds for as long as the signal is detected. The factory 
setting for 

Auto Mute

is on.

IntelliMute

IntelliMute

is a unique new feature that allows you to avoid alerts you 

don’t need to hear because you are stopped or moving slowly. By sensing 
the “revs” (RPMs) of your engine, IntelliMute knows when you are at low
speed and automatically mutes alerts (except for strobe signals from
emergency vehicles).

Before IntelliMute will work, you must set an activation point for your engine’s
revs (see page 11). Whenever the revs are below that point, IntelliMute will
begin muting. The activation point will be stored in memory and recalled 
each time the power is turned on. The factory setting is 

IntelliMute

Off.

NOTE

IntelliMute may not work with some vehicles because it cannot sense
the engine’s revs. In such cases, you can reduce unwanted audio alerts
by using 

Auto Mute

and 

City

mode when appropriate.

What to Remember While Using IntelliMute

IntelliMute

works with both 

City

and 

Auto Mute

modes.

Whenever your engine revs are below the activation point, 
the dot next to the large character on the right side of the display 
will remain lit. Above the activation point, the dot will blink twice 
every two seconds.

If, for any reason, the unit stops sensing your engine’s revs, 
IntelliMute will indicate an error and automatically turn Off.

The rev point you set will be stored in the unit’s memory when 
power is turned Off and recalled each time the power is turned On.

NOTE

The rev point must be reset if you use your detector in a different vehicle.

NOTE

When initially choosing your IntelliMute activation point, a setting 
of approximately 300 to 600 RPMs above idle is recommended. 
You can reset the activation point at any time to fit your individual
preferences and driving style.

Setting the IntelliMute Activation Point

Your detector must be installed in your vehicle.

CAUTION

Do not attempt to set the rev point while driving. 
Your vehicle should be parked and idling. 

IntelliMute must be turned on before setting the activation point. 
You will hear a series of beeps as you follow the steps on page 11.

Detection

Signals Detected

The tables on the following pages show you the types of 

Signals

your 

detector will detect, as well as the visual alerts it provides for each of them.

Audio Alerts

A distinctly different 

Alert 

tone is used for each type of signal detected

(including separate tones for each laser signal). For X, K, Ka and Ku band 
radar signals, the tones will repeat faster as you approach the signal 
source. The repeat rate of the tones gives you useful information about 
the signal detected. (See responding to alerts on page 16.)

Visual Display

An indication of the type of signal detected will appear in the UltraBright 
data 

Display

. During X, K, Ka and Ku alerts, a number will also appear,

indicating the strength of the signal detected. (1 = weakest, 5 = strongest)

During laser alerts the letter 

L

will appear, instead of the signal strength indication.

During VG-2 or Spectre 1 alerts, the letter 

V

will appear. It will be steady

during VG-2 and blink during Spectre 1.

During Safety Alert and Strobe Alert the letter 

S

will appear. It will be 

steady during a Safety Alert and will blink during a Strobe Alert.

Settings

Your Detector

VG-2 and Spectre 1 Alert Settings

Tone repeats slowly as you
approach a hill or bridge,
then speeds up sharply as
you reach it.

Probably police 
radar beyond the 
hill or bridge

FULL ALERT

Tone repeats slowly 
for a short period.

Probably a false alarm

Exercise caution

Any type of laser alert.

Laser alerts are 
never false alarms

Understanding Radar and Laser

Radar Speed Monitoring Systems

Three band frequencies have been approved by the Federal Communications
Commission (FCC) for use by speed monitoring radar equipment: 

X band

10.525 GHz

K band

24.150 GHz

Ka band

33.400 – 36.00 GHz

Your detector detects signals in all three radar bands, plus Ku band (13.435 GHz),
which is an approved frequency used in parts of Europe and Asia.

VG-2 and Spectre 1

VG-2

and 

Spectre 1

are “detector detectors” that work by detecting low-level

signals emitted by most radar detectors. Your detector does not emit signals
that can be detected by VG-2 or Spectre 1, but does detect VG-2 and Spectre 1
signals and will alert you when a device is in use near your vehicle, if you 
so choose.

Safety Alert Traffic Warning System

FCC-approved 

Safety Alert

transmitters emit microwave radar signals that

indicate the presence of a safety-related concern. Depending on the frequency
of the signal emitted, it can indicate a speeding emergency vehicle or train, 
or a stationary road hazard. 

Because these microwave signals are within the K band frequency, most
conventional radar detectors will detect Safety Alert signals as standard 
K band radar. Your detector, however, is designed to differentiate between
standard K band and Safety Alert signals, and give separate alerts for each.

Safety Alert technology is relatively new. Safety Alert transmitters can 
be found in limited numbers in all 50 states, but the number is growing.
Depending on your location, you may not receive these alerts regularly 
and may often encounter emergency vehicles, trains and road hazards 
without being alerted. As the number of transmitters increases, 
these alerts will become more common. 

When you receive such an alert, please watch for emergency vehicles ahead 
of you, on cross streets and behind you. If you see an emergency vehicle
approaching, please pull over to the right side of the road and allow it to pass.

Instant-On Detection

Your detector is designed to detect 

Instant-On

speed monitoring signals,

which can suddenly appear at full strength.

NOTE

You should take appropriate action 
immediately whenever an instant-on alert is given.

Strobe Alert

Special strobes mounted on the light bars of authorized emergency 
vehicles (fire trucks, police cars, ambulances) automatically change traffic
signals as the vehicle approaches an intersection. These strobes and the
special strobe detectors located on the traffic signals, introduced fairly
recently by 3M and Tomar, are already in use in more than 1000 cities
nationwide. Cobra’s exclusive 

Strobe Alert

detector will detect these 

special strobes and give an emergency vehicle alert. 

When you receive such an alert, please watch for an approaching 
emergency vehicle and pull over to allow it to pass. To inquire about 
coverage in your area, contact your local fire and police departments.

LIDAR (Laser)

The correct name for the technology that most people refer to as 
laser is actually 

LIDAR

, which stands for Light Detection and Ranging.

LIDAR operates much like radar. Its signal spreads out like a radar 
signal, though not as widely. Unlike radar, LIDAR must have a clear 
line of sight to its target vehicle throughout the entire measurement 
interval. Obstructions such as sign posts, utility poles, tree branches, 
etc., will prevent valid speed measurement.

Some common questions about LIDAR include:

Does weather have any affect on LIDAR?

Yes. Rain, snow, smoke, fog, or airborne dust particles will reduce the 
effective range of LIDAR and can, if dense enough, prevent its operation.

Can LIDAR operate through glass?

Yes. Newer LIDAR guns can obtain readings through most types of glass.
However, the laser pulse also can be received through glass to trigger 
an alarm by your detector.

Can LIDAR operate while in motion?

No. Because LIDAR operates by line of sight, the person using it cannot
drive the vehicle, aim and operate the gun all at the same time.

Is LIDAR legal to use?

Yes. It is legal in all 50 states.
