Wiring connection
Electrical protection
• Your fishfinder has an internal electrical
protection system for over voltage and
short circuit situations. It is not necessary
to use a fuse or a circuit breaker.
If possible, route the transducer cable away from
other wiring on the boat. Electrical noise from
engine wiring, bilge pumps, and other equipment
can affect the display.
• Both the power and depth transducer
cables lead into one four pin connector on
the FISH400 or the eight pin connector on
the FISH440. This plugs into a single
socket in the rear of the instrument.
Connect the red wire of the two-core
power cable to the positive supply and the
black wire to the electrical ground. The
shortest and most direct connection to the
boat’s battery will help to eliminate any
problems due to voltage drop or electrical
interference.
Finally, drill a hole and insert the third screw in
the middle of the bracket. It is advisable to fill
holes with a sealing compound before inserting
screws (see fig. 3.3).

• Other Types of Transducers
It is possible to use your NAVMAN Fish Finder
with all the NAVMAN Transducers Range
(including thru-hull mounting). For this purpose
you need to purchase the Y adaptors for the
FISH400 and FISH440, which will allow you to
separate the power cable from the transducer’s
cable.
