Cleaning

DO NOT use harsh solvents such as
benzine or alcohol when cleaning,
because they will damage the transceiver
surfaces.

Replacing fuse

If a fuse blows, or the transceiver stops functioning,
find and repair the cause of the problem. Then replace
the damaged fuse with a new, adequately rated fuse.
The fuses are installed in the DC power cable and the
circuitry in the body, to protect the transceiver.
