14 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-7000 has three of fuses (DC power cable fuses

⋅2, circuitry fuse⋅ 1) installed for transceiver protection.

•DC power cable fuses	ATC20 30 A
•Circuitry fuse	ATC20 5 A

CIRCUITRY FUSE REPLACEMENT

The 13.8 V DC from the DC power cable is applied to all units in the IC-7000, except for the power ampli- fier, through the circuitry fuse. This fuse is installed in the FRONT unit.

R WARNING: NEVER attempt to remove fuse

coverusing your finger nails, this may result in in- jury.

■Memory backup

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, memory, set mode contents, etc. is stored in this EEPROM. There is no internal lithium battery.

■Cleaning

If the transceiver becomes dusty or dirty, wipe it clean with a dry, soft cloth.

AVOID the use of strong chemical solvents such as thinner, benzine or alcohol to clean the transceiver. These may damage the transceiver’s surfaces.
