10-5. GENERAL.
This section provides the troubleshooting procedures used to isolate a defective antenna base.
10-6. OPERATIONAL CHECK.
The operational check provides a step-by-step procedure for evaluating an antenna base. If the operational
check is passed, the antenna base can be returned to service. If it does not pass the test, dispose of the
defective antenna base. The troubleshooting procedures are in paragraph 10-7.
The operational check is divided into steps. Each step verifies a particular function. Follow the instruction in the
“Action” column. Check the response. If the response is correct, proceed with the next lettered step. When a
STEP has been completed, proceed with the next STEP. A "No response" in the “Response’’ column means that
any response is not of interest.
The switch settings for the test equipment are given in the ’’EQUIPMENT PRESETS” section of each test setup
figure.
Connect the test setups only when directed, and with the power supply set to OFF. The large
current capacity of the test power supply can cause personal injury. Verify the test setup before
turning the power supply ON.
