Chapter 1: Important information
Certified Installation
Raymarine recommends certified installation by a
Raymarine approved installer. A certified installation
qualifies for enhanced product warranty benefits.
Contact your Raymarine dealer for further details,
and refer to the separate warranty document packed
with your product.
Warning: Product installation and
operation
This product must be installed and
operated in accordance with the
instructions provided. Failure to do so
could result in personal injury, damage
to your vessel and/or poor product
performance.
Warning: Corrosion
To prevent corrosion, NEVER install a
transducer with a bronze housing on a
vessel with a metal hull.
Warning: High voltages
This product may contain high voltages.
Do NOT remove any covers or otherwise
attempt to access internal components,
unless specifically instructed in the
documentation provided.
Warning: Positive ground systems
Do not connect this unit to a system which
has positive grounding.
Warning: Switch off power supply
Ensure the vessel’s power supply is
switched OFF before starting to install this
product. Do NOT connect or disconnect
equipment with the power switched on,
unless instructed in this document.
Warning: Transducer operation
Only test and operate the transducer in
the water. Do NOT operate out of water
as overheating may occur.
Caution: Power supply protection
When installing this product ensure the
power source is adequately protected
by means of a suitably-rated fuse or
automatic circuit breaker.
Caution: Do not cut transducer
cables
• Cutting the transducer cable severely
reduces sonar performance. If the
cable is cut, it must be replaced, it
cannot be repaired.
• Cutting the transducer cable will
void the warranty and invalidate the
European CE mark.
Caution: Service and maintenance
This product contains no user serviceable
components. Please refer all maintenance
and repair to authorized Raymarine
dealers. Unauthorized repair may affect
your warranty.
Transducer cleaning
Growth can collect on the bottom of the transducer,
this can reduce performance. To prevent the build
up of sea growth, coat the transducer with a thin
layer of water based antifouling paint, available from
your local marine dealer. Reapply paint every 6
months or at the beginning of each boating season.
Certain smart transducers have restrictions on where
antifouling paint is applied. Please consult your
dealer.
Note: Transducers with a temperature sensor may
not work properly if painted.
Note: Never use ketone based paint. Ketones
can attack many plastics possibly damaging the
sensor.
Note: Never use spray paint on your transducer.
Spraying incorporates tiny air bubbles, and a
marine transducer cannot transmit properly
through air.
Use a soft cloth and mild household detergent to
clean the transducer. If the fouling is severe, remove
the growth with a green scotch brite
TM pad. Be
careful to avoid scratching the transducers face.
If your transducer has a paddlewheel you can wet
sand with fine grade wet/dry paper.
Note: Harsh cleaning solvents such as acetone
may damage the transducer.
