6. The MTM800 Enhanced mobile terminal has the option of a GPS board. If a GPS or
combined TETRA/GPS antenna is used, make sure that the antenna has a clear view to the
sky and that the antenna base which carries the GPS receiver is not covered with any metallic
or radio frequency absorbing material.
Antenna Installation Procedure
1. Mount the antenna according to the instructions provided with the antenna kit. Run the
coaxial cable to the radio mounting location. If necessary, cut off the excess cable and install
the cable connector.
2. Connect the antenna cable connector to the radio antenna connector on the rear of the radio.
3. In case of an installed GPS board, connect the GPS antenna to the GPS antenna connector
on the rear side of the radio.

Completing the Installation
1. Mount the microphone clip to a convenient spot near your radio.
2. If your microphone has a telephone-type connector at the end of its cord, plug this connector
into the 10-pin TELCO connector of your Junction Box.
3. To complete your radio installation, plug the power cable into the radio power connector.
Any two metal pieces rubbing against each other (such as
seat springs, shift levers, trunk and hood lids, exhaust
pipes, and so forth) in close proximity to the antenna can
cause severe receiver interference.
DO NOT use the 10-pin TELCO connector of Data
Expansion Head Enhanced or Remote Head Enhanced
to plug in a microphone.
