After the unit has been powered for 10 minutes, the unit will send in a “power-up”
message that will include position.
If no GPS fixed has been acquired by the time the tests are complete, verify that the
unit is installed correctly, there is no metallic structure blocking the GPS signal from
the unit, and that the vehicle is outside. Call in and retest the verification of position.

Causes
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.
Unit Does Not Find
Cellular Service
The unit is not receiving the local cellular
system. The main cause of this is poor signal
strength due to shielding. Move the vehicle
outside the building and re-apply power to the
unit.
Unit Does Not Receive a GPS
Signal
The cause is that the GPS receiver is not
locking into the satellites. The main cause is
due to the receiver not receiving the signal from
the satellites. Make sure that the unit’s label is
facing towards the bottom of the vehicle. If it is,
then move the vehicle outside of any building/
garage to allow the internal GPS antenna in the
unit to have a clear view of the sky.
