Introduction
Congratulations! You have just purchased the
most sophisticated RADAR/LASER DETECTOR
available today.This booklet contains instructions
and information designed so that you will be able
to understand how the Cobra® ESD-9220 WX
works and how radar and (LIDAR) laser are used.
Enjoy your Cobra® ESD-9220 WX Radar/Laser
Detector and drive safely.
Federal Law Governing Use of
Radar Detectors
It is not against Federal Law to receive radar
transmissions on your COBRA® Radar Detector.
The Communications Act of 1934 guarantees
your right to receive radio transmissions on
any frequency. Local laws that contravene the
Communications Act of 1934, while illegal, may
be enforced by your local law enforcement
officials until and unless they are prohibited from
doing so by Federal Court action.
WARNING: Before leaving your car, make sure
that you conceal your radar detector. This will
reduce the possibility of break-in and theft of
your unit.
Included with your ESD-9220 WX
1. Windshield Bracket
2. Hook and Loop Material
3. Power Cord
and Strobe Alert™

Location
Selecting the proper location to mount the
Cobra® ESD-9220 WX is very important for
optimum performance. Both radar and laser
transmissions pass through glass but not through
other objects. For this reason the Cobra®
ESD-9220 WX lenses must not be blocked. It
should have a view of the rear window to take
advantage of LaserEye® 360˚ detection. It is best
to locate your detector as low on the front
windshield as possible.
Examples of metal in the windshield area that can
block or weaken incoming radar/laser signals:
1. Windshield wiper blades.
2. Mirrored sun screens.
3. Regular tinted glass does not affect radar
reception, although the darker tint at the
top of the tinted windshield prevents laser
light from penetrating.
4. Heated windshields, currently available as
an option for some Ford® (Instaclear) and
GM® (Electriclear vehicles act as an
impenetrable barrier to radar signals). If in
doubt, check with your dealer to see if this
applies to your vehicle.

Safety Alert® and Strobe Alert™ have

An emergency vehicle is approaching,
you are in the vicinity of a railroad

Exercise Caution.
Facts About the Safety Alert® Traffic
Warning System
FCC-approved Safety Alert® Transmitters emit
microwave radar signals to indicate the presence of a
safety-related concern. Depending on the frequency of
these signals, as set on the transmitter, the outgoing
signal can indicate whether the transmitter is on a
speeding emergency vehicle or train, or at a stationary
road hazard location.These microwave signals are
located in the K-band and as a result, any radar
detector which detects K-band radar will detect these
Safety signals as standard K-band radar alerts. However,
unlike a standard radar detector, your Cobra®
ESD-9220 WX is designed to differentiate between a
standard K-band alert and a Safety Alert® warning.
Safety technology is relatively new so the number of
transmitters in operation is still growing.You may not
receive Safety Alert® on a daily basis and should not be
surprised to encounter some emergency vehicles, road
hazards or trains not yet equipped with these
transmitters, therefore failing to provide a signal. As
Safety Transmitters become more prevalent (the
number of operating transmitters is growing every
day), these Safety Alerts® will become more common.
The Safety Alert® Transmitter is in use in all 50 states in
limited quantities.
Facts About Strobe Alert™
Alerts motorists to over 50,000 emergency vehicles
equipped with strobe transmitters that activate red
lights at traffic intersections in emergency high speed
situations.
Note
Strobe Alert™ is available
in over 1,000 cities and
works with Tomar and
Opticom systems. Call your
local Fire/Police
department for your area
coverage or area in which
you will be traveling.

Radar Frequencies
There are now three frequencies that have been
approved by the FCC (Federal Communications
Commission) for use in speed monitoring
equipment.They are:
X Band (10.525 GHz), K Band (24.150 GHz)
Ka Band (33.400-36.000 GHz)
Your Cobra® ESD-9220 WX can detect signals in
all three radar bands including photo radar and
STALKER radar which use the Ka band, and
Cobra®’s Safety Alert® signals on the K band.
Facts About LIDAR (Laser)
What is LIDAR?
LIDAR stands for Light Detection And Ranging.
While everyone refers to it as LASER the correct
name is LIDAR.
How does LIDAR work?
LIDAR operates a lot like RADAR. Like RADAR, it
spreads out. Not as quickly, but it does spread, as
shown on the diagram below.

a valid speed reading.

Facts About
LIDAR (Laser)
Does weather have any effect on LIDAR?
Yes, rain, snow, smoke, fog, and airborne dust
particles will all reduce the effective range, and
if sufficiently dense, may prevent its operation.
Can LIDAR operate through glass?
Yes, LIDAR guns can obtain readings through
most glasses.The laser pulse, however, can also
be received through glass to easily and quickly
trigger a laser detector's alarm.
Can LIDAR operate while moving?
No, since LIDAR is line of sight, an officer cannot
drive, aim, and shoot while driving.
Is a LIDAR DETECTOR legal to use?
Yes, it is legal in all 50 states.
