How to Replace the Fuse

The 5 A fuse (Type: FGBO-A 125V 5A PBF, Code No. 000-155-853-10) in the snap-
in fuse holder on the power cable protects the equipment from equipment fault and
reverse polarity of the power supply. If the equipment cannot be powered, the fuse
may have blown. Find out the cause for the blown fuse before replacing the fuse. If the
fuse blows again after replacement, contact a FURUNO agent or dealer for instruc-
tions.

2. Open the outer cover and shield cover. Turn on the #3 or #4 switch of DIP Switch
S2 as applicable.
#3: Restore default settings (IP address, etc.) except LAN related.
#4: Restore all default settings. Use this when changing transducers.
3. Connect the power cable to the DFF-3D, then turn on the power at the ship's
switchboard.
If #4 of DIP Switch S2 is set to ON, the LED blinks every 0.4 seconds.
4. Set up the transducer at the NavNet equipment, referring to chapter 3.
