TROUBLESHOOTING
Car
e And Maintenance
D
uring the summer months, avoid prolonged
e
xposure to direct sunlight by removing your unit
from the dash when your vehicle is parked for an
e
xtended period of time. Do not spray water,
c
leaners, or polishes directly onto the unit. The
spray may penetrate through the openings and
damage the unit. Also, do not use any abrasive
cleaners on the unit’s exterior.
As with all battery operated devices remove the
b
atteries when the unit will not be used for an
extended period of time. Damage caused by
leaky or improperly charged batteries are not
covered under warranty.
ARE DETECTORS LEGAL?
In Most States YES!
Laser-Radar detectors are legal in every state for
automobiles and light trucks (under 10,000 lbs.)
except Virginia and Washington, D.C., which
have local regulations restricting the use of
radar receivers in any vehicle.
The Federal Highway Administration (FHWA)
passed a nationwide regulation, effective
January 1994, which prohibited radar and laser
detector use in vehicles over 10,000 lbs.

SPEED MONITORING
Radar Facts
A radar gun operates by transmitting radio
waves at certain frequencies which reflect off
objects and are picked up by the radar gun’s
receiving section. When a radar beam reflects
off a moving target, a measurable frequency shift
occurs. The radar unit converts this shift into miles
per hour to determine your vehicle’s speed.
Currently, the FCC permits operation of traffic
radar guns at X Band (10.500 - 10.550 GHz), K
Band (24.050 - 24.250 GHz), and Ka Band (33.400
- 36.000 GHz).
Note: A radar detector will not alarm if an
officer is not transmitting on any one of the
above radar bands.
POP™ Mode
POP
Mode is a feature on some radar guns
operating on K and Ka bands. When the gun is
in POP
Mode and activated, a brief burst of
energy, less that 1/15 of a second, is transmitted
and the vehicle’s speed is quickly acquir
ed. A
detector without POP
Mode detection
capability cannot respond to this brief
transmission.
