Cleaning the transducer

The transducer normally needs little attention. However, the
transducer face should be inspected and cleaned when docking.
Note
Do not paint the transducer array with traditional hull plating
paint. Use only the correct type of paint approved by Simrad.
Do not use metal tools or high pressure water on the transducer
array.
Procedure
1 Ensure that the distance between the vessel hull and the
bottom of the dry dock is sufficient to lower the transducer
array.
2 In the Motor Control Unit, set the mode selector switch
to position LOWER.
