INSTALLATION AND CONNECTIONS

■ Mounting the EX-2780 scanner unit

D Location
The scanner unit is designed for high-pressure water
jet resistance (except for the cable connectors). Select
a place for installation that meets the following impor-
tant conditions.
➥ 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 that will
interfere with the scanning beam.
➥ Keep the scanner unit away from any exhaust pipes.
Exhaust gas can damage the unit.
➥ 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.
➥ The unit should be placed as high as possible on
the boat to obtain best performance with maximum
range.
➥ If you install two or more radar in one boat, install
one above, and the other(s) below.
➥ The mounting surface must be parallel with the
boat's waterline.
➥ If the height is insufficient to install the scanner unit,
build a special frame for installation.
