4 LEDs, Check Pins, and Switches by PCB
Among the LEDs, check pins, and switches that are mounted on this ADF, only those that
are required for surviving it in the field are mentioned below.
Check pins that are not mentioned on the list are intended for factory use
only. Special tooling and instrumentation are required to make adjustments
and checks using these check pins. These pins require critical accuracy and
must not be touched in the field.
4.1 ADF Controller PCB
Some LEDs illuminate slightly even when off, because they carry leak current under nor-
mal conditions of operation. These LEDs should not be recognized as signifying faults.
