8.4 Fuse Replacement
Use the proper fuse.
Use of a wrong fuse can result in damage
to the equipment.
WARNING
The fuses in the processor and transceiver units protect them from overvoltage,
equipment 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.
Unit Fuse Type Code No.

8.5 Fan Replacement
The processor unit has a fan, and its life is about 25,000 hours, in ambient
temperature of 50°C.
If the fan stops, because the area around the power supply is too hot, the power
voltage may fluctuate. Contact a FURUNO agent or dealer to request
replacement of the fan.
