– City I mode does not recognize X band
transmissions.
– Highway mode recognizes all bands and is
recommended for highway driving. (Default)

MONITORING SPEED
A radar gun transmits radio waves at certain frequencies
that bounce off objects and return to the radar gun's
receivers. The radar gun then calculates the speed of the
object. The LRD450 recognizes the following bands/
frequencies used by radar guns:
BAND
FREQUENCY
X
10.525 GHz
K
24.150 GHz
Ka
33.400 - 36.000 GHz
Laser
800 nm - 1100 nm
RADAR DETECTOR DETECTORS
(RDDS)
Radar detectors are illegal in some states. Law enforcement
officers use special equipment to detect signals radiated by
radar detectors. If they are in a state where radar detectors
are illegal and the officer detects a vehicle using a radar
detector, the operator of that vehicle could lose the radar
detector and be fined.
The LRD450 is designed to be invisible to signals from the
Spectre l, Spectre lV, and VG-2 RDDs.
CARE AND MAINTENANCE
Use common sense and your LRD450 will provide trouble-
free service. Please keep the following tips in mind:
• Don't leave your unit on the dashboard during summer
months. Interior heat may exceed safe operating levels.
• Do not spray cleaners or other liquids on the unit.
Remove the unit when you are using these liquids.
• Do not use abrasive cleansers on the unit's exterior.
