MAINTENANCE
■ Fuse replacement
If a fuse blows or the transceiver stops functioning, try
to find the source of the problem, and replace the dam-
aged fuse with a new, rated fuse.
CAUTION:DISCONNECT the DC power cable
from the transceiver when changing a fuse.
The IC-756PROIII has 2 types of fuses installed for
transceiver protection.
• DC power cable fuses ................................ FGB 30 A
• Circuitry fuse ................................................FGB 5 A
DC POWER CABLE FUSE REPLACEMENT
30 A
fuse
■ Clock backup battery replacement
The transceiver has a lithium backup battery
(CR2032) inside for clock and timer functions. The
usual life of the backup battery is approximately 2
years.
When the backup battery is exhausted, the trans-
ceiver transmits and receives normally but cannot re-
tain the current time.
See p. 106 for battery location.
CIRCUITRY FUSE REPLACEMENT
The 13.8 V DC from the DC power cable is conver
ted to 5 V or 8 V and applied to all units in the IC-
756PROIII, except for the power amplifier, through
the circuitry fuse. This fuse is installed in the PA unit.
q Remove the top cover as shown on p. 105.
w Remove 11 screws from the PA shielding plate,
then remove the plate.
e Replace the circuitry fuse as shown in the diagram
below.
r Replace the PA shielding plate and top cover.
Circuitry fuse (FGB 5 A)
PROBLEM POSSIBLE CAUSE SOLUTION REF.
DISPLAY

- Split frequency operation 76
- Split frequency operation allows you to transmit and receive in the same mode on two different frequencies the split frequency operation is basically performed using 2 frequencies on the main and sub readouts 76
- Split lock function accidentally releasing the xfc switch while rotating the tuning dial changes the receive frequency to pre vent this use both the split lock and dial lock func tions to change the transmit frequency only the split lock function cancels the dial lock function while push ing xfc during split frequency operation 76
- The dial lock s effectiveness during split frequency op eration can be selected in the set mode for both re ceive and transmit frequencies or only the receive frequency p 100 76
