INSTALLATION AND CONNECTIONS
D
Mounting with the bracket
The mounting bracket supplied with the display unit
enables “dashboard” or “overhead” mounting.
1. Hold the mounting bracket up to the selected
location and mark pilot holes for the 5 installation
holes using the template. (p. 70)
2. Drill 5 holes of 7 mm (0.28 inch) in diameter.
3. Install the bracket using the bolts, nuts or
washers.
4. Attach the display unit to the bracket with the knob
bolts at an appropriate view angle.
NOTE:
For protecting the display, attach the front
cover on the display unit while the radar is not in
use.
D
Display unit
Install the display unit in a place that meets the
following important conditions:
• Near the wheel in the cabin so that you can easily
view the radar screen while facing the bow.
• To minimize interference, keep the distance more
than “COMPASS SAFE DISTANCE” (stated in the
serial number label on the rear panel) away from
the compass and your navigation receiver.
• A safe place from salt or fresh water splash or
immersion.
• A place where it is easy to operate the usual
maintenance or adjustments.
• A place that can support the weight of the display
unit.
• Do not locate the display unit subject to extreme
heat, cold, vibrations or direct sunlight.
D
Scanner unit
The scanner unit is designed for high-pressure water
jet resistance (except for the cable connectors.)
Install the scanner unit in a place that meets the
following essential conditions:
• Place the scanner unit horizontally at the vessel’s
center so that it can view in all directions. Make
sure that no objects interfere with the scanning
beam.
• Keep the scanner unit away from any exhaust pipes
to avoid damaging the unit with exhaust gas.
• If your vessel is equipped with a Radio Directional
Finder (RDF) system, keep the scanner unit at least
2 m (6.6 ft) away from the RDF antenna. Radiation
from the scanner unit may affect the measurement
data of RDF instruments.
• Locate the scanner unit as high as possible on the
vessel for maximum performance in the full range.
If the height is insufficient to install the scanner unit,
build a frame to mount it.
• When installing two or more radars on a vessel, do
not place the scanner units at the same height.
