location every day, but no radar
source is in sight.

or laser.

while within range of an emergency

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