Test and Troubleshooting Procedures.
Perform the procedures in table 4-7 to test and
troubleshoot a suspected faulty rf low power alarm
assembly. Always perform the procedures from the
beginning. When the steps of table 4-7 have been
performed with no abnormal indications, the rf low
power alarm can be returned to stock or normal
operation in the terminal. If an abnormal indication is
obtained during performance of the procedures, in-
structions to correct the problem are given in the
remarks column of table 4-7.
When the fault is
repaired, retest the rf low power alarm to confirm that it
is normal. See figure 4-8 for rf low power alarm
assembly component location and figure FO-3 for
schematic diagram. Refer to figure FO-3 for voltage
measurements.
