A three way joiner (part no. SDJ) is available as a separate

The Transducer is connected to the instrument via crimp termi-
nals. To ensure a good connection when fitting the terminals
to the Transducer cable, fold back the exposed wires over the
insulation before inserting into the terminal (Fig 4.19). Use a
good quality crimp tool to crimp the terminals.
The screen wire should be crimped into the same terminal as
the black (BK) wire.
The transducer wires are colour coded and correspond to the
clearly marked terminals on the rear of the instrument (Fig
4.20) -

IS12 has been designed to minimise the effects of interference
generated by the engine alternator. However, precautions
should still be taken by routing the cables away from the
engine compartment. Do not run the cables down trunking
carrying high current cables. The transducer cable should also
be kept separate from the boat's radio antenna cable.
Engines with spark ignition, also some refrigerators should be
fitted with suppressors. Your local agent should be able to
advise on this and supply suppression kits where necessary.
