Radar Speed Monitoring Systems

Three band frequencies have been approved by the Federal Communications
Commission (FCC) for use by speed monitoring radar equipment:
Secondary Icons
X band 10.525 GHz
K band 24.150 GHz
Ka band 33.400 – 36.00 GHz
Your detector detects signals in all three radar bands, plus Ku band (13.435
Notice
GHz), which is an approved frequency used in parts of Europe and Asia.
VG-2
VG-2 is a "detector detector" that works by detecting low-level signals emitted
by most radar detectors. Your detector 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. While no signal is being detected, press and hold the Dim
button for four seconds.
Your detector can be spotted by Spectre IV+ RDDs, but is invisible to VG-2 and
Spectre I RDDs. You can choose whether you want to be alerted to VG-2 and
Spectre I & IV+ RDD signals. The factory setting for VG-2 and Spectre I & IV+
alerts is Off. It is recommended to leave these Off unless you are concerned
about being monitored for having a radar detector.
The factory setting for VG-2 alerts is Off.

Intro Operation
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 widely. 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.
Some common questions about LIDAR include:
Does weather have any affect on LIDAR?
n
Yes. Rain, snow, smoke, fog or airborne dust particles will reduce the Notice
effective range of LIDAR and can, if dense enough, prevent its operation.
Can LIDAR operate through glass?
n
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 detector.
Can LIDAR operate while in motion?
n
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 it legal for police to use LIDAR?
n
Yes, LIDAR is allowed to be used in all 50 States by police. Your detector
detects LIDAR (laser).
