Radar/VG-2/Laser Alerts
Type of Audible Signal
Interpretation and Response
Your COBRA® ESD-9220 WX starts to
signal slowly, then increases in rate
very rapidly.
Most likely police radar.
FULL ALERT
.
Your COBRA® ESD-9220 WX
signals just once.
Most likely a false source, or could be
pulsed radar.
Exercise Caution
.
Very fast signal rate instantly.
Slow signal rate as you approach
hill or bridge. Sharp increase in signal
rate as you reach hill or bridge.
Most likely police radar on other side
of hill or bridge.
FULL ALERT
.
Radar or VG-2 close by has been
suddenly switched on.
FULL ALERT
.
Short-term, weak signaling;
series of such signals.
Laser will trigger 3 distinct audible
signals; one each for LTI 20-20, Ultra
Lyte and ProLaser.
Use Full Caution
. There are no false
laser signals.
Safety Alert® and Strobe Alert™ have
their own unique “European
Emergency” signal.
An emergency vehicle is approaching,
you are in the vicinity of a railroad
crossing, or you are approaching a
road hazard (construction site,
accident scene, etc.).
Most likely a false radar source.
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.
