Placing Units
Placing the communication unit
The communication unit should be placed in a ventilated area. To ensure adequate cooling
for the unit, a 10 cm unobstructed space must be maintained above and below the unit.
A space of 10 cm above the unit is also required to allow removal of units.
Locating the communication unit too close to a compass can affect compass performance.
The compass safe distance is 0.30 meters for both steering and standard compasses.
For grounding, see pages 13 and 18.
Six holes through the unit's mounting plate allow the unit to be fixed to a bulkhead or a
desktop.
Placing the ISDN handset
The ISDN handset functions as a display and
communication unit for alert transmission. It may also be
used for normal voice communication. Up to two (2) ISDN
handsets may be connected in series. The units may be
installed anywhere onboard the vessel.
Four separate ISDN ports are available on the
communication unit as RJ45 jacks or screw terminal blocks.
