Mounting the EX-2474 scanner unit
• Location
WARNING:
BE SURE [POWER] is OFF when-
ever you are working with the scanner unit.
The scanner unit is designed to be weatherproof and
completely watertight. Select a place for installation
which meets the following important conditions.
q The scanner unit must be near the boat's center line
and have a good view in every direction. Be sure
there are no objects in the surrounding area which
will intercept the scanning beam.
w KEEP the scanner unit away from any smoke-
stacks. Smoke can damage the unit.
e When the boat is equipped with a radio directional
finder (RDF) system, keep the scanner unit at least
2 m (6.6 ft) away from any RDF antenna.
•Radiation from the scanner unit can affect the measure-
ment data of RDF equipment.
r The unit should be placed as high as possible on
the boat to obtain best performance with maximum
range.
t If you install two or more radar in one boat, install
one above, and one below.
y The mounting surface must be parallel with the
boat's waterline.
u If the height is insufficient to install the scanner unit,
build a special frame for installation.

q Drill four holes of 12 mm (1/2 in) in diameter using
the template.
• The template is provided on p. 45.
w If the mounting surface or platform is metal, apply
sealing compound around the holes to prevent cor-
rosion and to waterproof the unit.
e Fix the scanner unit to the selected position with
bolts of 10 mm (3/8 in) in diameter, with flat and
spring washers. The supplied bolts are two lengths:
25 mm (1 in) or 50 mm (2 in).
