4. INSTALLATION

NOTICE
The installation of this equipment requires
certain electrical and mechanical skills. If the
owner of the equipment has doubts about his
or her technical abilities, we recommend that
the equipment be installed by a qualified
technician.
4.1 Mounting Considerations
When selecting a mounting location for the
unit keep in mind the following points.
• The unit is designed and constructed to
be splashproof, thus it can be installed
outdoors. You can even hose it down af-
ter a day's outing. If it is to be installed
outdoors, we recommend installing it an
enclosed cabinet, for maximum protec-
tion against the marine environment.
• The temperature and humidity of the
mounting location should be stable and
moderate. No LCD can provide adequate
contrast if the ambient temperature is too
extreme.
• The unit consumes only a moderate
amount of power, so there is no need for
forced air ventilation. However, you
should provide adequate space behind and
around the unit to permit circulation of
air and to provide convenient access to
the rear connectors.
• Even though the picture is quite legible
even in bright sunlight, keep the display
unit out of direct sunlight or at least
shaded because of heat that can build up
inside the cabinet.
• Locate the unit in a position where you
can view and operate it conveniently but
where there is no danger of salt or fresh
water spray or immersion.
• The orientation of the unit should be so
26
the screen is viewed while the operator is
facing in the direction of the bow. This
makes determination of your position
much easier.
• Make sure you allow enough clearance
both to get to the connectors behind the
unit and to allow you to get your hands
in on both sides to loosen or tighten the
mounting knobs. Make sure you leave at
least a foot or so of "service loop" of
cables behind the unit so it can be pulled
forward for servicing or easy removal of
the connectors.
• A magnetic compass will be affected if
placed too close to the unit. Observe the
minimum compass safe distances to pre-
vent deviation of a magnetic compass:
standard compass, 0.7 meters, and stan-
dard compass, 0.5 meters.

4.2 Mounting Procedure

The unit is designed to be mounted on a
tabletop.
1) Using the hanger as a template, mark
screw locations in the mounting location.
2) Fix the hanger to the mounting location
with four M6 tapping screws (supplied).
3) Fit the knob bolts to the unit.
4) Install the unit in the hanger.
5) Tighten the knob bolts securely.
