TROUBLESHOOTING
Your Whistler detector is expertly engineered
and designed 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 the fuse in the plug; replace if
necessary with a 2 amp, 3AG type.
• Check the fuse for lighter socket; replace if
necessary.
• Make sure the lighter socket is clean.
PROBLEM: Unit alarms when vehicle hits
bumps.
• Check for a loose lighter socket; tighten and
clean.
• Check the connections at both ends of the
power cord. Substitute another cord to
determine if the cord is defective. Return the
defective cord to the factory.
PROBLEM: Audio alerts are not loud
enough.
