NOTE:
You must perform the PFN V DC adjustment described in part B
whenever the transceiver assembly A2 or the power supply card A1A1
is replaced.
Signal names and test point nomenclature are given in all capital

As you read earlier, this lesson includes only the test sequences and
troubleshooting tables for the low voltage power test and the receiver test
(see appendix B). The TM uses the same format and organization for each of
the 12 tests.
Below is a brief description of the format and procedures
used throughout TM 9-1260-477-34-2. For each test procedure, you will note
the following columnar format.
