Troubleshooting
PROBLEM
Detector beeps brie y at the same location
every day, but no radar source is in sight.
Detector did not alert when a police car was in
view.
Detector’s audible alerts become softer after the
rst few alerts.
The power-on sequence reoccurs while you are
driving.
You wish to restore the factory default settings.
The device will not turn on.
The display is blank.
SOLUTION
A motion sensor or intrusion alarm is located
within range of your route. If you have AutoLearn
enabled, the factory default setting, then MAX 4
will store this signal after about 3 passes and no
longer alert to it.
O cer may not have radar or laser unit turned
on. VASCAR (Visual Average Speed Computer
and Recorder), a stopwatch method of speed
detection, may be in use.
Detector is in AutoMute mode. See “AutoMute”
in the Settings & Preferences section for details.
A loose power connection can cause MAX 4 to
be brie y disconnected and will retrigger the
power-on sequence. Check all connections.
Press and hold the MRK and BRT buttons while
powering on the detector. A “Factory Settings
Restored” message will display, acknowledging
the reset.
Check that vehicle ignition is on.
MAX 4 is in Dark mode. Press the BRT button to
adjust the brightness.
