INSTALLATION OF YOUR NEW LASER/RADAR DETECTOR INSTALLATION The LRD 767/LRD777 uses a highly sensitive horn-type antenna and IR laser sensor to receive laser/radar 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 767/LRD 777 in a location where it will obstruct your driving vision. • Most vehicles have the top part of the windshield tinted. Mounting the LRD 767/LRD 777 behind tinted or mirrored glass may reduce the effectiveness of laser detection by reducing the amount of laser light received by the dectector. 8
