User manual UNIDEN LRD737 OPERATING GUIDE

[. . . ] ® LRD 737 Operating Guide Precautions Important: The LRD 737 was not designed to help you disobey the law. 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 some amateur radio equipment. [. . . ] Audio Button -- Press the audio button to activate the Audio Alert Only operation. P, C, and M LEDs dim, and the other LEDs are disabled. Note: To operate with visual alert only, set the volume control to the minimum. Remember though, that if the volume control is turned down and Audio Only operation is selected, the alarm features are completely disabled. Mute Button -- Press the mute button to activate the Auto Mute feature, which produces a full alert level when a signal is first received, then automatically reduces the volume for the rest of the warning. 4. 5. 5 6. DC 13. 8V Power Input -- Connect the DC power cord here. 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 737 in a location where it will obstruct your driving vision. · Most vehicles have the top part of the windshield tinted. Mounting the LRD 737 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 laser sensor are located at the rear panel of the unit, (and the rear-looking laser sensor is 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 Adjusting the Windshield Mounting Clip 1. 2. The metal portion of the bracket locks into the plastic portion at three different positions. These positions can be used for vehicles with different vertical angles of their windshields. The back position can be used for vehicles with windshields that are slanted back. [. . . ] When this alert sounds, you should tune to local radio traffic reports or prepare to slow down or stop your vehicle because you could be approaching an accident, bad road conditions caused by weather, or road crews or construction. 17 Care and Maintenance The LRD 737 is designed to give you years of trouble-free service. There are no user-serviceable parts inside, and, except for the fuse, no maintenance is required. To keep your detector in new condition, follow these important suggestions: · Never leave the LRD 737 on the windshield when you park your vehicle. The temperature in the vehicle in summer can reach levels above what is considered to be safe for this unit. [. . . ]
