Installation Guidelines
!
Warning: A radar unit should only be installed by a quali ed marine technician, as
improper installation poses risks to the installer, the public, and to the safety of the vessel.
!
Warning: Before commencing any installation or maintenance on the Halo radar make
sure the safety switch on the rear of the pedestal is set to OFF
There is a transmit interlock that prevents radar transmissions if the scanner is not rotating.
However, a high voltage remains for a period of time after the system is turned o . If you are
not familiar with this type of electronics, consult with a trained service or installation technician
before attempting to service any part of the equipment.
Installation includes:
• mechanical mounting
• electrical wiring
• con guring the display or network system to work with the radar
• adjusting the radar for proper performance
The radar’s ability to detect targets depends greatly 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, please consider:
• The length of the 20 m (66 ft) interconnection cable supplied with the radar is usually su cient.
A longer 30 m (98 ft) cable is available. 30 m (98 ft) is the longest the cable that can be used.
• If the roof of the wheelhouse is the highest existing location, consider installing a radar mast or
tower on which you can mount the radar. You may also need to construct a working platform
for your own safety during installation and servicing work.
• If you locate the scanner on the mast, position it on the forward side so that there is a clear view
to the front of the vessel.
• It is preferable to install the scanner parallel to the line of the keel.
DO NOT DO THIS!
• DO NOT install the scanner too high up, where its weight will alter the stability of the vessel and
cause degrade the radar picture over short ranges.
• DO NOT install the scanner close to lamps or exhaust outlets. The heat emissions may cause the
equipment to break down. Soot and smoke will degrade the performance of the radar.
• DO NOT install the scanner close to the antennas of other equipment such as direction  nders,
VHF antennas, GPS equipment etc, as it may cause interference.
• DO NOT install the scanner where a large obstruction (such as an exhaust stack) is at the same
level as the beam. The obstruction is likely to generate false echoes and/or shadow zones. If
no other alternative location use the sector blanking feature in the radar software. (see “” on
page 27)
• DO NOT install the scanner where it will be subjected to strong vibrations because the
vibrations could degrade the performance of the radar.
• DO NOT install an open array close to halyards or  ags because the wind could wrap these
around the antenna and jam it.
