Rules for transducer handling

To secure long life and accurate results, the transducer must be handled correctly.
A transducer must always be handled as a delicate instrument. Incorrect actions may damage
the transducer beyond repair. Observe these transducer handling rules:
1 Do not activate the transducer when it is out of the water.
2 Do not handle the transducer roughly and avoid impacts.
3 Do not expose the transducer to direct sunlight or excessive heat.
4 Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean
the transducer face.
5 Do not damage the outer protective skin of the transducer face.
6 Do not lift the transducer by the cable.
7 Do not step on the transducer cable.
8 Do not damage the transducer cable, and avoid exposure to sharp objects.
Transport protection
Some transducers are delivered with a cover plate to protect the face during transport and
installation. Let this plate stay on as long as possible, but do not forget to remove it before
the vessel goes to sea.
Cleaning and painting the transducer face
During normal use, the transducer is subjected to biological fouling. If this marine growth is
excessive, it will reduce the performance of the ES120-7C.
The transducer has not been designed with any protection against biological fouling.
Whenever opportunity arise, typically when the vessel is dry-docked, the transducer face
must be cleaned for shells and other marine growth.
• Be careful so that you do not accidentally make cuts or inflict other physical damage to
the transducer face.
• Remove biological fouling carefully using a plastic brush, a suitable synthetic detergent
and fresh water. Biological material which is strongly rooted in the substrate can be
removed carefully with a piece of wood or plastic.
• Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean
the transducer.
Anti-fouling paint may be applied to the transducer face. To minimize the negative
acoustical effects the layer of anti-fouling paint must be as thin as possible.
