2. PHYSICAL INSTALLATION
The Haas GPS monitoring unit is self-contained. It does not require an external antenna. Both the
GPS antenna and the cellular antenna are built-in. A Basic Installation requires only three wired
connections: one wire for Power (constant 12Volt), one for Ignition and the last one for Ground. The
Basic Installation consists of three simple steps: A) finding a place to position the monitoring unit, B)
testing for signal strength, and C) mounting the unit in place and providing power.
A: PLACEMENT
First, find a location for the Haas GPS monitoring unit. The unit must be placed in a horizontal
position with its label facing up to ensure that the built-in antennae can receive signals. It should not
be located directly underneath any metal. However, plastic, fiberglass, glass and cloth coverings are
acceptable. Following those guidelines, there are many places where the Haas GPS monitoring unit
can be positioned.
• Connect the BLACK wire from the wiring harness to a proper grounding point. Check with a
meter if you are not sure.
• Connect the RED wire from the wiring harness to a constant 12-volt positive power.
• Connect the YELLOW wire from the wiring harness to 12-volt ignition.
B: POWER UP UNIT AND TEST FOR SIGNAL
Make sure the back-up battery switch is in the OFF position. The battery switch is located on top of
the unit. The vehicle should be located outdoors and away from large obstructions, such as tall
buildings, that could block GPS signals. Place the monitoring unit in the desired position, making sure
you can see the red and green LEDs.
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 (may take up to 5 minutes depending on cellular and
Note: Be sure not to use T-Taps or Scotch Locks.
Notes:
Make sure that the vehicle’s windows are not covered with any reflective metallic film
that could block GPS signals.
The windshields and/or windows of certain types of vehicles (including some
Mercedes-Benz models and some BMWs) may have coated glass that can impede
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 Text-N-Track H1000 monitoring unit.
