Safe drivers always obey the posted speed limit and legal driving methods at all times. Federal and Local Regulations The FCC passed the Communications Act in 1934 to give all citizens the right to receive any type of radio transmission. The same radio frequencies used by police radar are also used by other devices, such as automatic door openers, burglar alarms, and

Color profile: Disabled Composite Default screen Introduction Welcome to the world of sophisticated, early warning laser/radar detection. You have purchased one of the most advanced laser/radar detectors available. The LRD 737 is a completely integrated laser/radar detector. It responds to the X-, K-, and Ka-SuperWideband radar guns in use today and also provides front/rear laser detection of the latest speed monitoring system — the laser gun. The built-in Safety Warning System (SWS™) is capabl

Color profile: Disabled Composite Default screen Speed Detection Systems A speed detection device (often called a radar gun) sends out either a microwave signal or beam of light. When this signal reaches its target, part of the signal is reflected or bounced back toward the emitting gun. The time required for the signal to leave the gun, bounce off an object, and return is used to determine a vehicle’s distance and speed. Radar Radar (Radio Detection and Ranging) is a microwave system for detec

Color profile: Disabled Composite Default screen Laser The Laser Speed Detection System, also called LIDAR (for Light Detection and Ranging), uses a laser gun that emits infrared light pulses just outside the spectrum of visible light. Each reflected pulse measures the speed of the object coming toward or going away from the laser gun. There are two Laser signals: Laser and Laser 2. Unlike radar, the laser gun emits a very narrow beam of light, so it can pinpoint a speeding car within traffic.

Color profile: Disabled Composite Default screen Installation The LRD 737 uses a highly sensitive horn-type antenna and IR laser sensor to receive radar/laser signals. Its sensitivity and range depend on the method of installation and the direction of the antenna/sensor in relation to the signal source. The inherent nature of radar waves makes them reflect off metallic surfaces. This is why these waves are so useful for measuring the speed of a vehicle. The IR laser light may reflect only from
