X/K/Ka Super Wideband (220-1648) Troubleshooting Faxback Doc. # 3410 Radar Detector If the detector does not turn on: * Be sure all power connections are secure. * Check the fuse that controls power to the cigarette-lighter socket. See the vehicle's owner's manual. * Check the fuse in the cigarette-lighter plug. * The cigarette-lighter socket might be dirty. Clean it with fine emery cloth to give a good, clean connection. CAUTION: Do not place any metal object other than the cigarette lighter or a cigarette-lighter plug in the cigarette-lighter socket. Doing so could blow a fuse in the vehicle or cause the metal object to become very hot. If the detector gives a false alert when the vehicle hits bumps: * Check the power connections. If the detector gives a false alert when you use vehicle accessories such as power windows, motorized mirrors, brakes, and so on: * Check the vehicle's electrical system, including the main battery cable and alternator connections. * Install a filter capacitor (470 microF, 35 volts, such as Cat. No. 272- 1030) on the back of the cigarette-lighter socket, across the power connections. If the detector successfully performs the self-test, but does not respond to radar signals: * A police car might not be equipped with radar, or might be using instant-on radar. * Police might be using VASCAR or LIDAR-type speed detection. If you are unable to solve the problem after trying these suggestions, the detector might require service. Take it to the local Radio Shack store for assistance. (CJD/all-12/05/94)
