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 in- stalled outdoors, we recommend installing it an enclosed cabinet, for maximum pro- tection 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 moder- ate 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.
