SELECTING A LOCATION
It is advisable to spend a little time selecting the best location for your GX750. The radio is a
modular design which allows the main unit to be discretely mounted out-of-sight behind the
dashboard or control panel. The chosen location should provide sufficient space to reach the
connectors and allow some airflow for the heat sink. The GX750 is supplied with a 500 mm
interconnecting lead, so select a location that is within 500 mm of the panel socket that will
connect to the LCD controller microphone.
For larger vessels where the main units may need to be mounted further away, a 6 meter inter-
connecting cable is available as an accessory (LE107).
Keep the following points in mind when choosing a location
•
The GX750 is designed to meet IPX7 standard. However we recommend you select a
location that will minimise excessive exposure to continuous rain or spray.
•
Select a location that won’t expose your radio to continuous direct sunlight which could
cause overheating.
•
Ensure the location allows a free flow of air around the heat sink on the main unit.
•
The LCD Controller Microphone should be readily accessible from the normal steering or
driving position. If required, an extension speaker can be installed to provide sound in other
parts of your vessel e.g. inside the cabin. The extension speaker connects to the main unit
•
Components and currents in the radio create magnetic fields. To avoid interference to
compasses, ships autopilot sensors etc, the GX750 should be mounted at least 300 mm from
such devices.
INSTALLING THE MAIN UNIT
The main unit is designed to be installed to a flat surface using four bolts or screws (depending
on the mounting surface material). First choose the desired mounting location for the LCD
controller microphone and panel socket as these will determine the approximate location for the
main unit. The main unit will need to be installed within 500 mm of the panel socket.
Once the location has been determined, simply place the main unit in the correct location and
mark the screw holes with a pen or pencil. Drill the holes while being mindful of any objects that
may be behind the panel. Fix the main unit with stainless steel screws or bolts.
Note that the 8 pin socket is quite heavy and once installation is completed, should be
supported using a cable tie as shown.
