8.4 Fuse Replacement
The fuses in the processor and transceiver units protect them from overvoltage, equip-
ment fault and reverse polarity of the ship's mains. If the power cannot be applied, first
check the fuse for the processor unit. The fuse for the transceiver unit is inside the unit;
have a qualified technician check the fuse. If a fuse blows after replacement, or the
power cannot be turned in spite of normal fuse, contact your dealer for advice.
8.5 Fan Replacement
The processor unit has a fan, and its life is about 25,000 hours, in ambient tempera-
ture of 50°C.
If the fan stops, because the area around the power supply is too hot, the power volt-
age may fluctuate. Contact a FURUNO agent or dealer to request replacement of the
fan.
