I
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, rated fuse.
the DC power cable from the
transceiver when changing a fuse.
The IC-706MKIIG has 2 types of fuses installed for
transceiver protection.
• DC power cable fuses .................................... 30 A
• Circuitry fuse ............................ F.G.M.B. 125 V 4 A
The 13.8 V DC from the DC power cable is applied to
all units in the IC-706MKIIG, except for the power
amplifier, through the circuitry fuse. This fuse is
installed in the PA unit.
I
All of the CPU's memory is backed up by an EEP-
ROM (Electronically-Erasable Programmable Read-
Only Memory). All data you set, such as VFO, memo-
ry, set mode contents, etc. is stored in this EEPROM.
There is no internal lithium battery.
I
If the transceiver becomes dusty or dirty,
wipe it clean with a dry, soft cloth.
30 A fuse
4 A Fuse
the use of strong chemical solvents
such as thinner, benzine or alcohol to clean
the transceiver. These may damage the
transceiver's surfaces.
