3.2 Replacing the Fuse
The fuse (2A) inside the FA-30 protects it from overcurrent and equipment fault. If the
unit cannot be powered, that is, the PWR (power) LED is off, the fuse may have blown.
If this happens, turn off the power to the FA-30, open the cover and check the fuse. If
the fuse has blown, find out the reason before replacing it. If it blows again after re-
placement, contact a FURUNO agent or dealer for advice.
