Where to Mount Your Unit 

You will get optimum performance from
your ESD-9050 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. You can 
also mount it directly on the dashboard. 

The unit's lenses 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,

®

consult your 

dealer to see if you have this option)

Highway/City Mode

Setting your ESD-9050 to City mode 
delays all X band audio alerts at lower
signal strength levels. (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. 

To change settings, follow the procedure in
the table below, which indicates what you 
will see and hear as you complete each step.

The factory setting is Highway mode.

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 4 seconds
for as long as the signal is detected.

Signals Detected

The tables on the following pages show 
you the types of signals your ESD-9050 
will detect, as well as the voice and 
visual alerts it provides for each one.

Audio Alerts

A distinctly different alert tone is used for
each type of signal detected. For X, K and
Ka 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, page 11.)

Visual Display

An indication of the type of signal 
detected will appear in the UltraBright™
Data Display. 

During laser alerts the letter ”L“ will appear.

During VG-2 Alert

®

the letters ”V/S“ will

appear.

During Safety Alert

®

the letter ”V/S“ 

will appear.

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 ESD-9050 detects signals in all three
radar bands.

VG-2

VG-2 is a "detector detector" that works 
by detecting low-level signals emitted by
most radar detectors. Your ESD-9050 does
not emit signals that can be detected by 
VG-2, but does detect VG-2 signals and 
will alert you when a device is in use 
near your vehicle.

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 
ESD-9050, 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.

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 ESD-9050.

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.

Some common questions about LIDAR include:

U N D E R S TA N D I N G   R A D A R   &   L A S E R

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
quickly. 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.

without the need for service. No routine
maintenance is required.

If your unit does not appear to be 
operating properly, please follow 
these troubleshooting steps:

Make sure the power cord is 
properly connected.

Make sure the socket of your vehicle's
cigarette lighter is clean and free 
of corrosion.

Make sure the power cord's cigarette
lighter adapter is firmly seated in your
cigarette lighter.

Check the power cord fuse. (Unscrew
the ribbed end cap of the cigarette
lighter adapter and examine the fuse. 
If required, replace it with a 1-amp 
fuse only.)
