R WARNING! BE SURE the radar’s power is OFF*
whenever you are working with the scanner unit.
* The radar’s power automatically turns OFF approx. 30 sec.
after the display unit’s power is turned OFF.
When 2 display units are connected to the
MarineCommander™, all units’ power must be turned OFF.
The scanner unit is designed for high-pressure water
jet resistance (except for the cable connectors). Select
a place for installation which meets the following im-
portant 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.
DMounting
q Drill four holes of 12 mm (
1
⁄2 in) in diameter using
the supplied template.
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 Attach the scanner unit to the selected position with
the supplied bolts (M10×40 mm), flat and spring
washers.
CAUTION: SECURE the four bolts firmly.
