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.

another cord to determine if cord is defective. Return
defective cord to the factory.
PROBLEM: Unit alarms when using vehicle equipment,
electrical accessories (brakes, power mirrors/windows,
directionals, horn, etc.), or when accelerating.
