of some information, and it can change the operating mode.
Avoid running the Fishfinder power wires near the power wiring for any
radar, radio, or Loran-C units. If possible, wire the Fishfinder power
wires to a separate circuit breaker.
• If the transducer cable runs near another electrical wire, it may pick up
electrical interference or "noise." To reduce this, try to keep the
transducer cable separated as far as possible from all other wires.
This is especially important with wiring for the boat's ignition,
alternator, or tachometer. It is also helpful to keep the transducer
cable away from the Fishfinder power cable. If it is necessary to run
the transducer cable across any wires, make the crossing at a right
angle.
• Use only genuine Raymarine cables. During the installation, do not
cut the transducer cable or remove the connector. Do not try to
shorten or splice the cable. The transducer cable includes several
wires, along with shielding and insulation. If the cable is cut, it cannot
be repaired. (Cutting the cable will also void the warranty.) During
installation, if you need to drill any holes for the cable, they must be
large enough to accept the connector. This will allow you to make the
installation without cutting the wire.
• A "suppression ferrite" may be attached to one of the cables. See Fig.
2-12. If you must remove the ferrite during installation, be sure to
reassemble it in the same position.
