1. Radar Installation
This chapters illustrates the instructions on electrical connections of the Radar
and the necessary software settings to operate it.
WARNING
In order for the Radar to communicate with the Chart Plotter, the software
configuration explained in the Par. 1.7 is mandatory.
1.1 INSTALLATION CONSIDERATIONS
Prior to the actual installation of the RADAR scanner unit, several factors must be
considered to ensure maximum performance. The scanner must be located so
that passengers and crew are not exposed to the direct Radar beam. The scanner
unit should be mounted on the centerline of your vessel in a location that has an
unobstructed view forward and the rest of the area around the scanner is as
unobstructed as possible. A location as high as practical to improve maximum
range is preferable, keeping in mind that minimum range objects may be over-
looked if mounted too high. Place the units in before large structures and exhaust
stacks. Large structure or stacks cause blind spots. Contamination from engine
exhaust on the scanner housing reduces radar performance.
Antennas for GPS, radio communication or other equipment should not be in the
radar beam. Use non-metallic extension poles to move the active area of anten-
nas above the radar beam.
In selecting a location, consider the suitability of the mounting surface. It must be
flat and approximately levelled with the vessel’s water line. The surface must
support the weight of the scanner and have access to the under side for installa-
tion of the four mounting bolts.
NOTE The recommended mounting surface thickness is 3/8 to 1/2 in. (9 mm to 13
mm). If the mounting surface is thin, a doubler should be added. If it is
thicker, longer bolts must be purchased. The scanner will be damaged if bolts
penetrate more than 9/16 in. (15 mm).
Also, consider the cable route from the scanner to the operator’s location. Avoid
routing the interconnecting cable through areas of possible damage from moving
objects, machinery, and exposure to chemicals or high temperature.
1.2 PREPARE THE RADAR FOR INSTALLATION
Unpack your new RADAR and check that the contents correspond to the packing
list. Do not remove the cover from the unit. There are no connections or adjust-
ments inside the unit that are needed for installation or operation. The cable
must remain attached. For ease of handling, coil the cable and place it on top of
the scanner. Then secure it with tape. Invert the scanner and make sure the four
mounting holes are clear to accept bolts.
Working at higher elevations may become necessary while installing the scanner
unit. Observe safety measures and take sufficient precaution to avoid personal
injury or damage to the equipment.
