Troubleshooting
24
Problem
STi MAGNUM beeps briefly at the
same location every day, but no
radar source is in sight.
STi MAGNUM does not seem
sensitive to radar or laser.
STi MAGNUM did not alert when a
police car was in view.
STi MAGNUM did not provide a
Safety signal while within range of
an emergency vehicle.
STi MAGNUM’s display is not
working.
STi MAGNUM’s audible alerts are
less loud after the first few alerts.
STi MAGNUM bounces or sags on
windshield.
STi MAGNUM’s power-on sequence
reoccurs while you are driving.
Possible Cause
• An X-band 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 STi
MAGNUM’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 MAGNUM 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.
• Check programming to be sure the STi MAGNUM is not in
Dark Mode.
• STi MAGNUM is in AutoMute Mode. See page 8 for details.
• STi MAGNUM is not making contact with the windshield
to provide stability. While holding down STi MAGNUM’s
QuickMount button, slide STi MAGNUM toward the wind-
shield so that the back top edge makes firm contact.
• A loose power connection or dirty lighter socket can cause
STi MAGNUM to be briefly disconnected.
