Troubleshooting
Problem
The V940 beeps briefly at the same
location every day, but no radar
source is in sight.
The V940 does not seem sensitive
to radar or laser.
The V940 did not alert when a
police car was in view.
The V940 did not provide a Safety
signal while within range of an
emergency vehicle.
The V940’s display is not working.
The V940’s audible alerts are less
loud after the first few alerts.
The V940 bounces or sags on wind-
shield.
The V940’s power-on sequence
reoccurs while you are driving.
Solution
• An X or K-band motion sensor or intrusion alarm is located
within range of your route. With time, you will learn
predictable patterns of these signals.
• Make sure that windshield wipers do not block your V940’s
radar antenna and that the laser lens is not behind tinted areas.
• Determine if your vehicle has an Instaclear
®
, ElectriClear
®
or
solar reflective windshield which may deflect radar or laser
signals.
• Your V940 may be in City Mode.
• VASCAR (Visual Average Speed Computer and Recorder) a
stopwatch method of speed detection, may be in use.
• Officer may not have radar or laser unit turned on.
• Safety transmitters may not be commonly used in your area.
• Press the BRT button to deactivate Dark Mode.
• The V940 is in AutoMute Mode. See page 8 for details.
• The V940 is not making contact with the windshield to
provide stability. While holding down the V940’s QuickMount
button, slide the V940 toward the windshield so that the back
top edge makes firm contact.
• A loose power connection or dirty lighter socket can cause
the V940 to be briefly disconnected.
