Stinger S650 12 Radar detector
Troubleshooting
If the detector does not turn on:
• Make sure that the POWER is in the ON position.
• Check the power cord or battery. Be sure all power connectors are properly
installed.
• Check the fuse that controls power to the cigarette lighter socket. See your
vehicles owner's manual.
• The cigarette lighter socket might be dirty. Clean it with fine emery cloth to
ensure a good, clean connection.
• Vehicle electrical problem exists.
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 or bumps:
• Check the vehicle's electrical system, including main battery cable and
alternator connections.
• Install a filter capacitor (470uF/25volts) on the back of the cigarette lighter
socket across the power connections.
If the receiving signals are weak:
• Check the angle of detector.
• Point to the horizon.
• Radar antenna / laser sensor is obstructed.
• Relocate the detector clear of any obstruction outside the windshield, such
as a wiper blade (see mounting manual).
