PROBLEM:
Unit alarms when vehicle hits bumps.
• Check for loose lighter socket; tighten and clean.
• Check connections at both ends of the power cord.
Substitute another cord to determine if the cord is
defective. Return defective cord to the factory.
PROBLEM:
Unit falses too much.
• If your country only uses 34.0 or 34.3 GHz use Ka
Narrow Mode.
• If your country uses all of Ka band, switch to Ka Norm.
• If alarms are POP Ka, switch POP Mode to off.
• If the above option doesn’t help, use a higher Ka Filter
setting.
• If alarms are X or K band and due to radar based traffic
flow sensors or radar based vehicle blind spot
detectors, use a higher X/K Filter setting.
If difficulties occur which cannot be solved by information in
this Troubleshooting Guide, please call Whistler Customer
Service at 1-479-273-6012 or visit our FAQ page at

service.

ARE DETECTORS LEGAL?
Check with your country’s laws reguarding radar detector
ownership and use.
It is the responsibility of the individual radar detector
user to know and understand the laws in your area
regarding the legality of the use of radar detectors.
POP™ Mode
POP™ Mode is a feature on some radar guns operating on K
and Ka bands. When the gun is in POP™ Mode and
activated, a brief burst of energy, less that 1/15 of a second, is
transmitted and the vehicle’s speed is quickly acquired. A
detector without POP™ Mode detection capability cannot
respond to this brief transmission.
Laser Facts
It’s well documented that many radar guns cannot reliably
provide the speed of a targeted vehicle that is traveling in a
group of vehicles. In contrast, a laser gun can target a specific
vehicle out of a line of traffic and determine its speed. The
advantage of laser over radar in terms of target identification is
the result of the laser gun’s narrow beam. A radar gun’s
transmission can cover more than a four-lane highway at a
distance of 1,000 feet, compared with a laser gun’s transmission
which covers about 3 feet at the same distance.
