CHAPTER 5
OPERATOR MAINTENANCE
5-1. GENERAL
Operator maintenance consists of routine tasks and specific checks and services that are needed to
keep equipment in a “ready to use” condition. Routine tasks such as cleaning, checking cables for
damage, stowing items not used and checking for loose bolts, nuts and screws must be performed
whenever the operator sees that they are necessary and are, therefore, not listed in the following tables.
Visually inspect the radio set often, especially for damaged antennas. Be sure that cables are positively
connected, and do not show breaks, cuts and other damage. Make sure that the radio set is assembled
properly and ready for operation. Perform these checks before starting any mission, and also after
every mission.
After the visual checks, perform a communication check by contacting another radio station.
If a radio set fails to operate, refer to para. 5-3 for instructions.
During transmission, high RF voltages may appear at the RF
connectors, the antenna cable, and on the antenna itself. Avoid
touching the antenna and RF connectors when the radio set operates.
Make sure that the antenna is not located near high-voltage lines.
