5.2 Display Unit Installation
Mounting considerations
When selecting a mounting location for the display unit keep in mind the following points.
•The display unit is designed and con- structed 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 install- ing it an enclosed cabinet, for maximum protection against the marine environ- ment.
•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 mod- erate 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. Ob- serve the minimum compass safe dis- tances to prevent deviation of a magnetic compass: standard compass, 0.7 meters, and steering compass, 0.5 meters.
Mounting procedure
The display 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 display unit.
4)Install the display unit in the hanger.
5)Tighten the knob bolts securely.
