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 conve- niently and where the screen can be viewed while facing towards the bow.
•Locate the unit out of direct sunlight and way 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.
•The display unit is very heavy. 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 reinforce the mounting location.
•Determine the mounting location considering the length of the signal cable be- tween the scanner unit and the display unit. (The signal cable comes in lengths of 15, 20 or 30 meters; maximum 100 meters).
•Leave sufficient space on the sides and rear of the unit to facilitate mainte- nance. 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 mag- netic compass: Standard compass, 1.70 m, Steering compass, 0.90 m.
