installed under the vehicle’s rear shelf, behind the rear passenger seat and above
the trunk. Position the unit in place and proceed to Step B to check the signal
strength.
OR
- On-or-under-the-dash option
Another option is to install the CompuTrack GPS monitoring unit on or under
the dash (space permitting and provided the dashboard deck is non-metallic.)
Position the unit in place and proceed to Step B to check the signal strength.
B: Check Signal Strength
Make sure the battery switch is in the OFF position (the battery switch is located
on top of the unit). The vehicle should be located outdoors and at least twenty
feet away from large obstructions that could block GPS signals, such as a tall
building. Place the monitoring unit in the desired position, making sure you can
see the red and green LEDs.
Provide temporary power to the monitoring unit. There are several ways to pro-
vide temporary power to the unit, including:
- Use a cigarette lighter power adaptor equipped with a 5-amp fuse and a 10-pin
Molex connector to attach to the CompuTrack GPS monitoring unit.
OR
- Use an A/C transformer equipped with a 5-amp fuse and a 10-pin Molex con-
nector to attach to the CompuTrack GPS monitoring unit.
OR
- Use the wiring harness that is included with the CompuTrack GPS monitoring
unit. Simply disconnect the wiring harness from the monitoring unit, mak-
ing sure the 5-amp fuse is in place and operational. Temporarily connect the
BLACK wire from the wiring harness to Ground, and temporarily connect the
RED wire from the wiring harness
to 12-volt Positive Power. Now plug the wiring harness into the mating recep-
tacle on the GPS monitoring unit. The unit should then have power.
When the monitoring unit receives power, the LEDs will begin flashing. The
GREEN LED will stop flashing after it has locked onto its cellular signal (usu
-
ally within 1 – 2 minutes); and the RED LED will stop flashing when it locks
onto its GPS signal (usually within 2 – 3 minutes). Signal strength is confirmed
when both
LEDs stop flashing.
If the LEDs do not stop flashing, the GPS monitoring unit should be re-posi
-
tioned in another location. Find another location for the monitoring unit and
confirm that the signal strength is acceptable before proceeding to the next step.
Notes:
Make sure that the vehicle’s windows are not covered with reflective metal
-
lic film that could block GPS signals. OEM in-glass defroster grids or anten
-
nas do not effect reception.
The windshields and/or windows of certain types of vehicles (including
some Mercedes-Benz models and some BMWs) may have coated glass that
can prevent radio signals from penetrating the vehicle. If you are not sure
about the windows, use the signal test procedure described above to find an
acceptable installation position for the CompuTrack GPS monitoring unit.
