Emc Servicing And Safety Guidelines - Raymarine hsb2 PLUS Owner's Handbook Manual

8-2
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 this 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
service technicians. They will ensure that service procedures and replace-
ment 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. In order to
minimise these effects and enable you to get the best possible performance
from your Raymarine equipment, guidelines are given in the installation
instructions, to enable you to ensure minimum interaction between differ-
ent items of equipment, i.e. ensure optimum Electromagnetic Compatibil-
ity (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 momentarily may
result in faulty operation.
