X K Ka Laser Detector (220-1653) Troubleshooting Faxback Doc. # 7228 If the detector does not turn on: Be sure all power connections are secure. Be sure the cigarette- lighter plug's tip is secure. Check the fuse that controls power to the cigarette-lighter socket. See your vehicle's owner's manual. Check the fuse in the cigarette-light plug. See "Replacing the Fuse." 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 your 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 main battery cable and alternator connections. Install a filter capacitor (470uF, 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 (See "Facts About Radar"). Police might be using VASCAR-type speed detection. (See "Non-Radar Speed Detection"). If the detector has poor laser detection: Be sure the laser window's view is not blocked. Use lens-cleaning solution to clean the laser window's lens. If you are unable to solve the problem after referring to this guide, the detector might require service. Take it to your local Radio Shack store for assistance. (ALL-9/15/94)
