Mount the connectors in the correct
order.
Each connector is secured using two
M3x8 bolts.
Note
Observe the special numbering
sequence!
This is a critical task. If you switch the
position of any of these connectors,
the SN90 will not be able to process
the echo data properly, and will then
not offer correct data.

Painting the transducer face
In order to reduce the marine growth (biological fouling) on the transducer face, it
may be covered with a thin film of suitable anti-fouling paint. The transducer must be
painted immediately after installation, and then again as often as required to maintain
the protection.
Prerequisites
The following tools and consumables are required.
• Personal protection
• Fresh water
• A mild synthetic detergent and a plastic brush
• Fine-grade sandpaper (240 inch grit size)
• Primer
• Anti-fouling paint
• Wet film gauge
Because some paint types may be aggressive to the polyurethane in the transducer,
consult our list of approved paints. The list can also be found on
.
