5 TRANSCEIVER UNIT
Introduction
Note
The Transceiver Unit must be mounted as a complete unit, i.e. the
door should not be opened until the unit is securely fastened to the
bulkhead.
Before mounting the Transceiver Unit, observe that the distance
between the Hull Unit and the Transceiver Unit is restricted by the
flexible transducer cable joining the two. Remember to take into
consideration the slack necessary to lower the transducer.
Caution
Do not fasten the transducer cable to the Transceiver Unit until
described later in the start-up procedure.
Free bulkhead space is required to mount the Transceiver Unit
cabinet.
