3.2 Mounting the Display Unit and Sub-Display Unit (option)
The display unit and sub-display unit are designed for tabletop mounting. When selecting a
mounting location, consider the following conditions:
• Place where operating personnel are able to control the unit easily while observing the fish-
ing ground or the area surrounding the vessel.
• Place at least 1 m away from a magnetic compass and equipment which have a magnet (radar
magnetron, loudspeaker, high power transformer, etc.).
• Place not exposed to direct sunlight, water splashes or hot air.
• Place where maintenance and ventilation clearance shown in the outline drawings is en-
sured.
• Place where the CRT face is within 45 from vertical.
Mounting the display unit/sub-display unit
1. Remove the mounting base by unscrewing the two bolts at the front bottom.
2. Fix the mounting base to the table by using four M10 bolts, flat washers, spring washers and
nuts. It is recommended that a rubber mat be placed under the mounting base to absorb
vibration.
3. Fasten the unit to the mounting base with two bolts. When the space around the unit is
limited, make wirings to the display unit first and then fasten the unit.
