speed is too high, or if the transducer shaft has been bent.

Docking the vessel

When docking the vessel, great care must be taken not to damage
the sonar trunk and protecting blister.
WARNING
The sonar must never be powered up when the
ship is in dry dock. The transducer will be damaged
if it transmits in open air. To prevent inadvertent
use of the sonar, set the main on/off switch on
the Processor Unit to Off, or disconnect the mains
power, whenever the vessel is in dry dock.
