to exacting quality standards to provide you with reliable,
trouble-free operation. If your unit has been correctly installed
following the guidelines in this manual, but is not operating
optimally, please refer to the troubleshooting guide below.
PROBLEM: No display or audio.
• Check fuse in Whistler plug; replace if necessary with a 2 amp
3AG type.
• Check fuse for lighter socket; replace if necessary.
• Make sure lighter socket is clean.
PROBLEM: Unit alarms when vehicle hits bumps.
• Check for loose lighter socket; tighten and clean.
• Check connections at both ends of power cord. Substitute an-
other cord to determine if cord is defective. Return defective
cord to the factory.
PROBLEM: Unit alarms when using vehicle equipment or
electrical accessories (brakes, power mirrors/windows,
directionals, horn, etc.).
• Vehicle's electrical system, including battery and alternator, may
have electrical noise. Install a filter capacitor (470mfd. 25 volt or
larger capacitance value) on the back of the lighter socket.
