DSM300 Installation Manual
Use only a water-based antifouling paint, or a water-based paint specifically
designed for transducers. Apply the paint with a brush.
If your transducer becomes fouled or stops working because of sand or sea
growth, use a stiff brush to clean it. You may sand the surface with a fine-grit wet
or dry sandpaper (#320 grade or finer), but this will affect the performance of the
unit when the boat is moving at higher speeds.
The paddle wheel mechanism may become jammed by dirt, grit or barnacles.
Work the contaminant out of the mechanism, then clean the unit with soap and
water or alcohol.
Cleaning the Hull
Use caution when sanding or cleaning the outside of the hull near the transducer.
CAUTION:
Harsh cleaning solvents such as acetone may damage the
transducer.
EMC Servicing and Safety Guidelines
• Raymarine equipment should be serviced only by authorized Raymarine ser-
vice technicians. They will ensure that service procedures and replacement
parts used will not affect performance. There are no user serviceable parts in
any Raymarine product.
• Some products generate high voltages, so never handle the cables/connec-
tors when power is being supplied to the equipment.
• When powered up, all electrical equipment produces electromagnetic fields.
These can cause adjacent pieces of electrical equipment to interact with one
another, with a consequent adverse effect on operation.
To minimize these effects and enable you to get the best possible perfor-
mance from your Raymarine equipment, guidelines are given in the installa-
tion instructions, to enable you to ensure minimum interaction between
different items of equipment, i.e. ensure optimum Electromagnetic Compati-
bility (EMC).
• Always report any EMC-related problem to your nearest Raymarine dealer.
We use such information to improve our quality standards.
• In some installations, it may not be possible to prevent the equipment from
being affected by external influences. In general this will not damage the
equipment but it can lead to spurious resetting action, or may result in
momentary faulty operation.
