car was in view.

signal while within range of an
emergency vehicle.

Your 14-year old son has changed
all 7 of the Programming options.
Solution
• An X-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 Pro300’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.
• Pro300 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.
• Pro300 is in AutoMute Mode. See page 8 for details.
• Pro300 is not making contact with the windshield to
provide stability. While holding down Pro300’s QuickMount
button, slide Pro300 toward the windshield so that the back
top edge makes firm contact.
• A loose power connection or dirty lighter socket can cause
Pro300 to be briefly disconnected.
You can return all of the programming options to the factory
defaults by holding down the CITY and BRT buttons while
you turn Pro300 on.
