Remote Mounting 19
Remote Mounting
General
In the remote mount version of the MTM300, the radio unit (transceiver) and the control
head are mounted in separate trunnions in the vehicle. A junction box interfaces the control
head and the transceiver through a pair of cables.
If purchased, a Junction Box with Data enables adding a laptop to the remote configuration.
Planning is the key to fast, easy radio installation. Before a hole is drilled or a wire is run,
inspect the vehicle and determine how and where you intend to mount the antenna, radio,
and accessories. Plan wire and cable runs to provide maximum protection from pinching,
crushing, and overheating.
The installation planning should only be undertaken by persons who are competent and
able to ensure that the complete installation fulfils its regulatory requirements, such as
EMC (ElectroMagnetic Compatibility).
To connect the MTM300, proceed as explained in the following paragraphs while referring
to Figure 19.
Installation Planning
The following list of considerations should, as a minimum, be checked during installation
planning:
• The best place for the transceiver is to place it on the trunk floor. Alternate locations
are under the front or rear seat, and under the rear speaker’s deck panel.
• Mount the control head horizontally at a position which enables the driver to view the
controls and operate them easily.
• Be sure the control head is close enough to the vehicle operator to permit easy access
to operating controls.
• Although the control head trunnion can be mounted on a plastic dashboard, it is
recommended that the mounting screws be located so they penetrate the supporting
metal frame of the dashboard.
• When mounting the junction box on the transmission hump, take care the transmission
housing is not affected. Prefer a hidden place, close to the control head.
• Wherever you place the units, ensure that it is protected from dirt and moisture.
• Verify that there is sufficient space around the units to allow air flow and removal.
• Check whether you have enough space to accommodate the power cable connector and
antenna coaxial cable.
• Verify that the antenna cable is routed in the shortest way, to minimize power loss over
the cable.
• Check that the mounting surface is able to support the weight of the units.
