Note of operator unit installation
1. Avoid direct sunlight, shock and vibration.
2. Power supply should be steady to avoid damage of high voltage.
3. Operator unit should be far away from the equipments which generate
electromagnetic radiation, such as: motors, generators.
Transducer
Transducer in the air must be avoided! This may cause mechanical
damage of the element.
Optimal system operation is achieved by fitting the transducer as deep as
possible on the hull. The surface of the transducer must be installed
horizontal. On vessels with a deep keel, if the transducer must be fitted
higher than the keel, it should be fitted towards the side, as far from the
keel as possible to avoid false keel echo.
Do not mount transducers close to the propeller or aft of other hull
installations (outlets, vents or other protruding details).
It is of course necessary to select a part of the hull that is submerged under
all load and speed conditions, and to avoid positions where air is trapped in
heavy weather.
Cleaning and maintenance
Clean the screen only with a damp cloth when dirty or covered in sea salt.
Avoid abrasive cleaners, petrol or other solvents.
Keep the transducer free of weed, paint and debris.
