9.10 System start-up
Introduction
To do the final tests, the vessel must be in the sea. This is
because the transducer always must be in water before you start
transmitting.
Warning: If the sonar system starts transmitting while the
transducer array is in o pen air, this may lead to
serious damage to the transducer and the
transmitters.
Preparations
In order to prepare the system start-up, carry out the following
operations in the Transceiver Unit and the Motor Control Unit.
1 Connect and fasten the transducer plug to the left-hand
side of the Transceiver Unit.
- Use the screws and washers applied for the protecting
cover.
2 Reinsert the fuses F204 and F205 on the HV power unit.
3 Set the hoisting/lowering switch S302 in the Motor
Control Unit to Remote position.

Starting up the transmitter
The following set of procedures requires two persons. One
person must be stationed on the bridge to operate the sonar,
while one must stay in the sonar room to make sure the
Transceiver Unit works properly. Make sure that proper
communication exists between the two locations.
Note: Should problems occur in the sonar room, the person in the
sonar room must set the service switch S202 to Off.
The following two procedures must be performed simultanously
by the person on the bridge and the person in the sonar room. To
simplify the test, remove the applicable pages from this manual.
