Fish 4430/4431 Installation and Operation Manual
2 Getting started
For deep-sea fishing with the FISH 4430/4431,
a rapid change in temperature may indicate
the edge of a warm or cold current. The
temperature difference can form a barrier, and
the fish may not swim through this. Search for
fish on either side of the barrier.
Cleaning and maintenance
The FISH 4430/4431 should be cleaned
with a damp cloth or mild detergent. Avoid
abrasive cleaners and petrol or other solvents.
Always cover or remove a transom-mounted
transducer when repainting the hull. If painting
over a through hull transducer with antifouling
paint then use only one coat of paint. When
repainting the transducer, remove previous
coats of antifouling paint by sanding it lightly.
When not in use, the FISH 4430/4431 can either
be removed from the installation bracket and
stored in a safe, dry, cool place such as the
NAVMAN carry bag, or left on the installation
bracket and securely covered with the optional
sun cover.
Power and transducer connection
FISH 4430
One end of the integrated transducer/power
cable has an 8 pin LT connector plug. Push this
plug into the socket located on the rear of the

sure that the collar is secure for a watertight
connection.

One end of the power cable has a black 8 pin LT
connector plug. Push this plug into the lower
socket, which has a black nut and is located on
the rear of the display unit, then turn the collar
to lock. Make sure that the collar is secure for a
watertight connection.
One end of the transducer cable has a blue
8 pin LT connector plug. Push this plug into
the upper socket, which has a blue nut and is
located on the rear of the display unit, then
turn the collar to lock. Make sure that the collar
is secure for a watertight connection.
If the transducer is not connected, the
message “NO TRANSDUCER DETECTED. ENTER
SIMULATION MODE?” will appear. Press
to switch between YES, NEVER or NO. (More
information on the simulation mode can be

confirm the selection and the startup sequence
will continue.
(
Note:
If the transducer was not intentionally dis-
connected, turn the display unit off and refer to the
section on Troubleshooting in Appendix B.)
