Marine life (barnacles, etc.) adhering to the transducer face will reduce sensitivity. Periodically remove any marine life from the transducer face with fine sandpaper or a piece of wood.

Painting will affect performance.

3.1.3 Fuse replacement

Fuses in the units of the system protect the electrical circuitry from burning by overcurrent. If the equipment cannot be energized check the fuse in the power cable connected to the display unit. Locate the cause before replacing the fuse.
