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 item. Wrongful 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, avoid impacts.
3
Do not
expose the transducer to direct sunlight or excessive heat.
4
Do not
use high pressure water, sand blasting, metal tools or strong solvents to
clean the transducer face.
5
Do not
damage the outer protective skin on 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, avoid sharp objects.
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 EM 712.
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, sand blasting, 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.
Note
The anti-fouling paint will reduce the acoustical performance of the transducer.
The surface roughness of the transducer substrate and the thickness of the paint may
also influence the performance.
Because some paint types may be aggressive to the polyurethane in the transducer,
consult our list of approved paints.
