1.2 Mounting the Processor Unit
The unit can be mounted on the deck, a desktop or on a bulkhead. Select a mounting
location considering the points below.
•
Locate the unit out of direct sunlight.
•
Select a location where temperature and humidity are moderate and stable.
•
Consider the length of the cable connected among the processor unit, antenna unit (or
power supply unit) and control unit.
•
For mounting on a bulkhead, be sure the mounting location is strong enough to support
the unit (4.1kg) under the pitching and rolling normally encountered on the vessel.
•
Leave sufficient space around the unit for maintenance and servicing. Recommended
maintenance space appears in the outline drawing at the back of this manual.
•
A magnetic compass will be affected if the processor unit is placed too close to the
magnetic compass. Observe the following compass safe distances to prevent disturbance
to the magnetic compass.
Standard compass: 1.75 m
Steering compass: 1.10 m
