Note
The quality of the welding is critical to the safety of the vessel. Welding must only be done
by a certified welder. If applicable, the final installation welds must be approved by the
vessel’s national registry, the corresponding maritime authority and/or classification society.
Observe the relevant rules and regulations related to welding.

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. A physical blow to the transducer face may easily damage one
or more elements. Observe these transducer handling rules:
• Do not activate the transducer when it is out of the water.
• Do not handle the transducer roughly. Avoid impacts.
•
Do not
expose the transducer to direct sunlight or excessive heat.
• Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean
the transducer.
• Do not damage the outer protective skin of the transducer.
•
Do not
step on the transducer cables.
• Do not damage the transducer cables. Avoid exposure to sharp objects.
Cleaning the transducer face
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.
