Transducer handling and maintenance
Cleaning the transducer face
Whenever opportunity arise, for example when the vessel is dry docked, the transducer
face may be cleaned for shells and other marine fouling. Be careful not to make cuts in
the transducer face. Use a piece of soft wood or a very fine grade emery paper.
Special rules for acoustic windows
Arctic tanks have acoustic windows made of polycarbonate. These must neither be
painted nor cleaned with chemicals. Acoustic windows must not be exposed to direct
sunlight.
Rules for transducer maintenance
Once installed, the transducer is maintenance free. However, when the vessel is docked,
it is highly recommended to clean the transducer face to remove marine growth.
1 Perform a thorough visual check of the transducer.
2 If necessary, clean the transducer
• To clean the transducer, use normal synthetic soap and water.
• To remove marine growth, use fine-grade sandpaper or emery paper.
Note
Do not use strong solvents.
Do not attempt to scrape of marine growth with sheets of metal, screwdrivers or
other metallic tools.
Do not use high pressure water to clean the transducer.
3
If necessary, apply a new layer of anti-fouling paint to the transducer face.
Because some paint types may be aggressive to the polyurethane in the transducer
face, please consult Simrad’s list of approved paints.
