9.4 Starting up the Hull Unit
Introduction
Observe the following procedure to start up the Hull Unit. To
ensure correct performance, tick off every item when the action
has been carried out.
Warning: Before starting up the sonar equipment on a
recently launched vessel, make sure the depth
under the keel is sufficient for the transducer to
be lowered safely.
When starting up the equipment on board a
vessel in dry dock, check first under the vessel
and inside the sonar room. Personnel, tools and
other potential obstructions must be kept clear of
the transducer and related lowering and hoisting
machinery to avoid personal injury or damage to
the equipment.
