FISH 4350 / 4380 Installation and Operation Manual26
NAVMAN
switching off other instruments, accessories
(e.g. bilge pump) and the motor until the
offending device is located. To stop
problems from electrical noise, try:
- re-routing the power and transducer
cable(s) away from the boat’s other
electrical wiring.
- routing the display unit’s power cable
directly to the battery with an in-line fuse.
4. Bottom is not displayed:
a) The Þ shÞ nder may have Manual Range
selected and the depth may be outside the
range value selected. Either change the
Þ shÞ nder to Auto Range or select another
depth range (see section 4-4 Range).
b) The depth may be outside the Þ shÞ nder’s
range. While in Auto Range, the display
unit will display “--.-” to indicate that there is
no bottom detected. A display of the bottom
should reappear when in shallower water.
5. The bottom is displayed too far up
the screen:
The Þ shÞ nder may have Manual Range
selected and the selected Range value is
too high for the depth. Either change the
Þ shÞ nder to Auto Range or select another
depth range (see section 4-4 Range).
6. Bottom echo disappears or erratic
digital reading while the boat is moving:
a) Ensure the back of the bottom surface
of the transducer is slightly lower than
the front and the front is as deep in the
water as possible in order to minimise the
generation of bubbles through cavitation.
(See the Transom Transducers Installation
Guide, for more information.)
b) The transducer may be in turbulent water.
Air bubbles in the water disrupt the echoes
returned, interfering with the Þ shÞ nder’s
ability to Þ nd the bottom or other targets.
This often happens when the boat is
reversed. The transducer must be mounted
in a smooth ß ow of water in order for the
Þ shÞ nder to work at all boat speeds.
c) Electrical noise from the boat’s motor
can interfere with the Þ shÞ nder. Try some
suppression spark plugs.
7. If the Þ shÞ nder beeps when turned on
but nothing is displayed:
The Þ shÞ nder may be operating, but the
backlight settings may have been set too
low. See section 2 Basic Operation, to adjust
the Þ shÞ nder backlight. (Press
twice)
8. The wrong language is displayed:
See section 3-1 Setup > System.
9. Fuel used or remaining seem inaccurate:
a) If the engine is run while the Þ shÞ nder is
powered off, the Þ shÞ nder does not record
the amount of fuel used during that engine
run. Consequently, the Fuel remaining
value will be higher than the actual amount
of fuel remaining in the tank.
To avoid this problem, use the Auto Power
Wiring option described in section 6-4 Wiring
options. This ensures that the fishfinder
powers on automatically whenever the
boat’s ignition is switched on.
b) In rough seas, fuel may surge back and
forth through the fuel transducer, resulting in
incorrect readings. Try installing a one-way
valve between the fuel transducer and the
fuel tank.
c) The Set remaining fuel value must be
reset after every refuelling (see section 3-3
Setup > Fuel).
d) The fuel tank may not reÞ ll to the same
capacity each time due to air pockets. This is
particularly noticable with underß oor tanks.
e) Fuel transducers wear out over time and
should be replaced after every 5000 litres
of fuel.
10. Flow indicates no fuel or low fuel:
a) Check that the number of engines is set
to 1. See section 3-3 Setup > Fuel.
b) Check that the fuel cable connectors are
securely plugged in and the collar is locked
in place. The collar must be locked in place
to give a watertight connection.
c) A fuel transducer may be clogged. If so,
remove the transducer from the fuel line
and gently blow through it in the opposite
direction to the fuel ß ow.
A fuel Þ lter between the fuel transducer
and the fuel tank must be installed as per
the fuel installation guide. Failure to do so
will void the warranty.
d) Inspect the fuel cable from end to end for
damage such as cuts, breaks, trapped or
squashed sections.
e) Check that the fuel Þ lter is clean.
11. A twin engine installation shows only
one ß ow rate:
a) Check that the number of engines is set
to 2. See section 3-3 Setup > Fuel.
