1.6 Mounting Methods for Display Unit
When selecting a mounting location for the display unit keep in mind the following
points.
•
The display unit is designed and constructed to be splashproof, thus it can be
installed outdoors. You can even hose it down after a day’s outing. If it is to be
installed outdoors, we recommend installing it an enclosed cabinet, for
maximum protection 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 display 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 display 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 display unit should be so the radar 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 display unit.
Observe the minimum compass safe distances to prevent deviation of a
magnetic compass: standard compass, 0.7 meters, and steering compass, 0.5
meters.
