Bridge steps
The hull unit provided with the SU90 is designed to lower the transducer down below
the ship’s hull when the SU90 shall be used. This is a key functionality of the SU90.
It is very important that the hoist/lower function is tested before the SU90 is put to
operational use. In order to test the lower and hoist functionality of the hull unit, two
tasks must be done simultaneously. These tasks are done on the bridge.
Prerequisites

turned on and operates normally. Neither tools nor instruments are required.
