1.2 Transceiver Unit

1.2.1 General mounting considerations

•
The mounting location should be well ventilated and dry.
•
The unit can be mounted on a bulkhead or a desktop. For bulkhead mounting, be sure
the bulkhead is strong enough to support the weight of the unit under the vibration
normally experienced onboard the vessel. If necessary, reinforce the mounting location.
•
Secure maintenance space for ease of maintenance and service, referring to the outline
drawing for recommended maintenance space.
•
The maximum length of the cable between the transceiver unit and the raise/lower drive
assy. is 30 m.
•
The maximum length of the cable between the transceiver unit and the display unit (or
interface) is 10 m.
•
A magnetic compass will be affected if the transceiver unit is placed too close to the
compass. Observe the following compass safe distances to prevent deviation to the
compass: Standard compass: 0.60 m, Steering compass: 0.35 m.

1.2.2 Mounting procedure

The transceiver unit may be mounted a desktop or a bulkhead. Fasten the unit to the
mounting location with four tapping screws (5 mm diameter, local supply).
For bulkhead mounting:
1. Screw in upper tapping screws, leaving 5 mm gap between bottom of screw head and
bulkhead as shown right.
2. Set the unit to the tapping screws and tighten screws.
3. Screw in lower tapping screws.
