TROUBLESHOOTING CHART
Symptom
Cause
Unit Does Not Power-up
Power is not connected to the unit. With a Digital Volt Meter,
measure the voltage at the input to the unit. A positive voltage
should be measured on the + terminal of the unit when measuring
between the + terminal and the - terminal or chassis ground. This
voltage should also measure 12 VDC. Correct the wiring to assure
the correct polarity and the correct voltage level. Check fuse. Bad
Ground connection. Make sure the ground is connected directly to
metal with no paint or residue. Use a Digital Multimeter to test
continuity to ground to ensure good connection.
Unit Does Not Find
The unit is not receiving the local cellular system. The main
Cellular Service
cause of this is poor signal strength due to shielding or coverage.
Make sure the GSM (Orange) light is solid, move the unit outside
the building and or outside of vehicle if necessary and re-apply
power to the unit. Move vehicle to acquire better signal if
necessary. Contact tech support if problem persists.
Unit Does Not Receive a GPS
Signal
The GPS receiver is unable to lock into the satellites or receive
signal. Make sure GPS (Green) light is solid if not, make sure that
the unit’s label is facing skyward and that there is no metal
between it and the sky including but not limited to the roof of the
vehicle and any dash bracing. If it is, the move the vehicle outside
of or away from any building/garage to allow the internal GPS
antenna in the unit to have a clear view of the sky. You may need
to power the unit outside of the vehicle as some vehicles may
have metallic or leaded windshields. Contact tech support if
problem persists.
