Radar/VG-2/Laser Alerts
Type of Audible Signal Interpretation and Response
Your COBRA® XR-1010 starts to signal
slowly,then increases in rate very
rapidly.
Most likely police radar.
FULL ALERT.
Your COBRA® XR-1010
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.
Radar Frequencies
There are 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® XR-1010 can detect signals in all
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.

Facts About
LIDAR (Laser)
LIDARs must have a clear
line of sight to target a
vehicle during the entire
measurement interval.
Intervening objects such as
signposts,utility poles,tree
branches,etc.,will prevent
a valid speed reading.
