Note: Follow these instructions carefully. Don’t take any shortcuts!
• The Broadband Radar is factory sealed. It is not necessary to remove the cover.
• Removing the cover will void the factory warranty.

Choose the scanner location
The radar’s ability to detect targets greatly depends on the position of its scanner. The ideal
location for the scanner is high above the vessel’s keel line where there are no obstacles.
A higher installation position increases the radar ranging distance, but it also increases the
minimum range around the vessel where targets cannot be detected.
When you’re deciding on the location, consider the following:
The length of the interconnection cable supplied w your radar is usually suffi cient. If you think
you’ll need a longer cable, consult your dealer before installation. Optional cable lengths are 10
m (33 ft), 20 m (65.5 ft) and 30 m (98 ft).
If you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain away
rapidly, and the breather hole in the base can operate .
The scanner is usually installed parallel to the line of the keel.
DON’T DO THIS!
• DON’T install the scanner too high up (eg at the top of a mast), which may cause
degradation of the radar picture over short ranges
• DON’T install the scanner close to lamps or exhaust outlets. The heat emissions may
damage the dome. Soot and smoke will degrade the performance of the radar
• DON’T install the scanner close to the antennas of other equipment such as direction
fi nders, VHF antennas, GPS equipment, as it may cause or be subject to interference
• DON’T install the scanner where a large obstruction (such as an exhaust stack) is at the
same level as the beam, because the obstruction is likely to generate false echoes and/or
shadow zones
• DON’T install the scanner where it will be subjected to strong vibrations because these
vibrations could degrade the performance of the radar
• DON’T install the scanner such that boat electronics with switch mode power supplies
(such as fi sh-fi nders and chart plotters) are in the beam of the antenna
• DON’T install the scanner directly on to a large fl at roof area. Use a pedestal to elevate the
scanner for radar beams to clear roof line (see “Considerations for direct roof mounting” on
page 8)
Dual Radar installation - Broadband Radar and Pulse Radar installation:
For dual radar installations, ensure Broadband Radar is not installed in the beam of the pulse
radar at any time.
