4-2 The display unit

1 Choose a location for the display unit that:
• is easily seen and protected from
damage
• is at least 100 mm (4") from a compass
and at least 500 mm (19.5") from a radio
or radar antenna
• is away from engines, fluorescent lights,
power inverters and radio or radar
transmitters
• is accessible from the back; a minimum
clearance of 50 mm (2") is required at
the back (see mounting diagram)
• protects the back of the unit from
moisture and water.
2 The unit must be mounted on a flat panel
less than 20 mm (0.75") thick. Stick the
mounting template in place. Drill a 50 mm
(2") fixing hole through the centre hole
in the template. Note that the template
allows space around the display unit for the
protective cover.
3 Remove the fixing nut from the back of
the display unit. Insert the stud at the back
of the display unit through the mounting
hole. Hand tighten the fixing nut.
Warnings
1. The display unit is waterproof from the
front. Protect the rear from water, otherwise
water might enter the breathing hole and
damage the display unit. The warranty does
not cover damage caused by moisture or
water entering the back of the display unit.
2. Ensure that any holes cut for the
installation will not weaken the boat's
structure. If in doubt, consult a qualified boat
builder.
