Communication unit
1) The communication unit can be installed al-
most anywhere provided the location satis-
fies the following conditions:
•The ambient temperature is between
-15˚C and +55˚C.
•Avoid installing the unit near air conditioners
and hot air vents.
•Select a location free of water splash and rain.
•Select a location where vibration is minimal.
•Locate the unit well away from magnetic
fields (generator, etc.).
•Keep the unit out of direct sunlight.
2) The communication unit can be installed on
a tabletop or a bulkhead. For bulkhead
mounting be sure the mounting location is
strong enough to support the weight of the
unit (4 kg) under the continued condition of
vibration normally encountered onboard the
vessel.
3) Leave at least 150 mm at the rear of the unit
to permit easy access to connectors.
Terminal unit
1) Observe installation guideline 1) above.
2) The installation angle must not be greater
than 15˚ to prevent disk drive malfunction.
Distress alert unit
Two units should be installed and one should
be installed near the steering place.
Mounting
Antenna unit
procedure
1. Locally prepare an antenna mast with a
ground stud (M6 stainless steel bolt welded
to antenna mast). (The distance between the
stud and the ground terminal on the antenna
unit should be within 370 mm, which also is
the length of the supplied ground wire.)
2. Weld the antenna mounting pipe (supplied)
to the antenna mast. (more than 60 ).
3. Fix the cable assembly N-H1054 (supplied)
to the antenna unit.
