Problem
The V8 beeps briefly at the same 
location every day, but no radar 
source is in sight.
The V8 does not seem sensitive to 
radar or laser.
The V8 did not alert when a police 
car was in view.
The V8 did not provide a Safety 
signal while within range of an 
emergency vehicle.
The V8’s display is not working.
The V8’s audible alerts are less loud 
after the first few alerts.
The V8 bounces or sags on 
windshield.
The V8’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 V8’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 V8 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 V8 is in AutoMute Mode. See page 8 for details.
• The V8 is not making contact with the windshield to 
provide stability. While holding down the V8’s QuickMount 
button, slide the V8 toward the windshield so that the back 
top edge makes firm contact.
• A loose power connection or dirty lighter socket can cause 
the V8 to be briefly disconnected.
