Installation The LRD 6299SWS/LRD 6399SWS 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 shiny surfaces. Both radar waves and IR laser light will, however, pass through plastic or glass. Before you decide where to put your radar detector, please keep in mind these two important factors: • For safety, do not mount the LRD 6299SWS/LRD 6399SWS in a location where it will obstruct your driving vision. • Most vehicles have the top part of the windshield tinted. Mounting the LRD 6299SWS/LRD 6399SWS behind tinted or mirrored glass may reduce the effectiveness of laser detection by reducing the amount of laser light received by the Detector. Helpful Tips The antenna and the forward looking sensor are located behind the rear panel of the unit, (and the rear- and side-looking sensors are located on top of the unit), directly behind the mode selection keys. The antenna and sensors should not be obstructed by metal or metallic surfaces and should be pointed at the horizon for accurate long-range detection. • Do not mount the unit behind the windshield wiper blades, radio antenna, tinted glass area, or mirrored glass. Be sure the unit is free from obstruction by seat backs, rear view mirror, sun visors, or the ceiling of the automobile. • Do not mount the unit in front of the heater or defroster vents. • Do not leave the unit in direct sunlight or in the glove compartment of a closed car for long periods of time, as extreme changes in temperature may cause internal damage. Also, removing the unit from the windshield makes you less susceptible to break-in and theft. 8
