This troubleshooting guide is written with the assumption that the user has read and understood the relevant sections in this manual.
It is possible in many cases to solve difficulties without having to send the display unit back to the manufacturer for repair. Please follow this troubleshooting section before contacting the nearest Navman dealer.
There are no user serviceable parts. Specialized methods and testing equipment are required to ensure that the display unit is reassembled correctly and is waterproof. Users who service the product themselves will void the warranty.
Repairs to the product may only be carried out by a service centre approved by Navman. If the product must be sent into a service centre for repair, it is essential to send in the transducer(s) at the same time.

1. The fishfinder won’t turn on:
a)The FISH 4432/4433 is designed to operate on a 12 volt battery system, where the voltage may vary from 10 to 16 volts. If an excessive voltage is supplied, the unit will turn off/not start.
b)Check that the power cable connector at the back of the display unit is securely plugged in and the collar is locked in place.
The collar must be secure for watertight connection.
c)Measure the battery voltage while the battery is under load - turn on some lights, radio or other electrical equipment connected to the battery. If the voltage is less than 10 volts:
-the battery terminals or wiring on the terminals may be corroded.
-the battery may not be charging correctly or may need replacing.
d)Inspect the power cable from end to end for damage such as cuts, breaks, squashed or trapped sections.
e)Ensure that the red wire is connected to the positive battery terminal and the black wire to the negative battery terminal. If wired for the Auto Power option, ensure the yellow wire is connected to the ignition circuit. Also check the boat’s main switch circuit (see section
f)Check for corrosion on the power cable connector and clean or replace if required.
g)Check fuses that are placed in line with the power cable. A fuse can be blown despite appearing to be good or the fuse may be corroded. Test the fuse or replace it with a fuse known to be good.
