1.2 Display Unit
Mounting considerations
When selecting a mounting location, keep in mind the following points:
• Select a location where the display unit can be viewed and operated conveniently and
where the screen can be viewed while facing towards the bow.
• Locate the unit out of direct sunlight and away from heat sources because of heat that
can build up inside the cabinet.
• Locate the equipment away from places subject to water splash and rain.
• Be sure the mounting location is strong enough to support the weight of the unit under
the continued vibration which is normally experienced on the ship. If necessary rein-
force the mounting location.
• Determine the mounting location considering the length of the signal cable between the
scanner unit and the display unit. (The signal cable comes in lengths of 15, 20, 30 or 60
meters; maximum 100 meters).
• Leave sufficient space on the sides and rear of the unit to facilitate maintenance. Also,
leave a foot or so of “service loop” in cables behind the unit so it can be pulled forward
for servicing or easy removal of connectors.
• A magnetic compass will be affected if placed too close to the display unit. Observe the
following compass safe distances to prevent deviation of a magnetic compass: Stan-
dard compass, 1.15 m, Steering compass, 0.90 m.
