Fuse replacement

If a fuse blows or the transceiver stops functioning,
try to find the source of the problem, and replace the
damaged fuse with a new, adequately rated fuse.

CAUTION:

Disconnect

the DC power cable

from the transceiver when changing a fuse.

The IC-7200 has two fuses (DC power cable fuses)
installed for transceiver protection.
• DC power cable fuses .............................. ATC 30 A
• Circuitry fuse .............................................. ATC 5 A

D

DC power cable fuse replacement

Refer the figure illustrated at right for the DC power
cable fuse replacement.

D

Circuitry fuse replacement

The 13.8 V DC from the DC power cable is applied to
all units in the IC-7200, except for the power amplifier,
through the circuitry fuse. This fuse is installed in the
PA unit.

q

Remove the 11 screws, then remode the bottom

cover and the PA shielding plate as shown below.

ATC 30 A fuse

e

Replace the circuitry fuse as shown in the diagram

as below.

Front panel

ATC 5 A fuse

r

Replace the PA shielding plate, bottom cover and

screws to their original position.

Be sure

the gasket is seated correctly, and do not

protrude from the transceiver when the PA shield-
ing plate is replaced.
