3.2 Display Unit Installation

Mounting considerations
When selecting a mounting location for the
display unit keep in mind the following points:
•
Keep the display unit out of direct
sunlight.
•
The temperature and humidity should be
moderate and stable.
•
Locate the unit away from exhaust pipes
and vents.
•
The mounting location should be well
ventilated.
•
Mount the unit where shock and vibration
are minimal.
•
Keep the unit away from electromagnetic
field-generating equipment such as
motors and generators.
•
For maintenance and checking purposes,
leave sufficient space at the sides and
rear of the unit and leave slack in cables.
•
Observe the compass safety distances
noted on page ii to prevent interference to
a magnetic compass.
•
Be sure the mounting location is able to
support the weight of the unit under the
continued vibration normally experienced
on the boat.
Mounting
The display unit can be mounted on a
desktop or on the overhead.
1. Fix the hanger to the mounting location
with four tapping screws (supplied).
2. Fit the knob bolts to the display unit.
3. Set the display unit to the hanger. Tighten
the knob bolts securely.
