3-Band Radar Detector  (220-1645)  Troubleshooting     Faxback Doc. # 6221

If the radar detector does not turn on:

   Be sure all power connections are secure.  Be sure the cigarette-
   lighter plug's tip is tightened.

   Check the fuse that controls power to the cigarette-lighter socket.
   See your vehicle's owner's manual.

   Check the fuse in the cigarette-lighter plug.

   The cigarette-lighter socket might be dirty.  Clean it with fine emory
   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 radar detector gives a false alert when the vehicle hits bumps:

   Check the power connections.

If the radar 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 (470 microF, 35 volts, such as Cat. No
   272-1030) on the back of the cigarette-lighter socket, across the power
   connections.

If the radar detector successfully performs the self test, but does not
respond to radar signal:

   A police car might not be equipped with radar, or might be using
   instant-on radar.

   Police might be using VASCAR-type speed detection.

If you are unable to solve the problem after referring to this guide, the
radar detector might require service.  Take it to your local Radio Shack
store for assistance.
