Radar/VG-2/Laser Alerts

Radar/VG-2/
Type of Audible Signal
Laser Alerts
Your COBRA® XR-1050 starts to signal
slowly, then increases in rate very
rapidly.
Your COBRA® XR-1050
signals just once.
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.
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.
Safety Alert® and Strobe Alert™ have
their own unique "European
Emergency" signal.

Interpretation and Response
Most likely police radar.
FULL ALERT.
Most likely a false source, or could be
pulsed radar. Exercise Caution.
Radar or VG-2 close by has been
suddenly switched on. FULL ALERT.
Most likely police radar on other side
of hill or bridge. FULL ALERT.
Most likely a false radar source.
Exercise Caution.
Use Full Caution. There are no false
laser signals.
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.).

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-1050 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
30 FT. WIDE
signposts, utility poles, tree
branches, etc., will prevent
a valid speed reading.
