12. MAINTENANCE (ADVANCED) Cleaning D O NOT use harsh solvents such as benzine or alcohol when cleaning, because they will damage the transceiver surfaces. If the transceiver becomes dusty or dirty, wipe it clean with a dry, soft cloth. 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. L Spare fuses are supplied with the transceiver. The fuses are installed in the DC power cable and in the inside circuitry, to protect the transceiver. ••DC power cable fuses ATC 30 A ••Circuitry fuse ATC 5 A RWARNING! ••Disconnect the DC power cable from the transceiver before replacing the fuse. ••NEVER use fuses that are not specified. DDDC power cable fuses See the following illustration to replace the DC power cable fuses. ATC 30 A fuse 85
