Applying Power
Two key switches on the inner front panel control power to the ADFM. A
third momentary key switch provides a reset function. Ensure that both
power switches are in the "off" position, and the reset switch is not held in
the "reset" position. Connect the appropriate power supply cables to the
ADFM and the power source, if required. Ensure that the batteries are se-
curely mounted in the ADFM and that the battery supply wiring harness is
attached. Use the supplied switch-key to switch the appropriate power
source switch(es) to the On-position, indicated by "1"; this will power-up
the ADFM. If you intend to use both mains and battery power, ensure that
both switches are on.

Built In Tests (BITs)
When power is first applied to the ADFM, an internal self-test will auto-
matically be performed. Result messages will scroll on the LCD display,
culminating in a display showing the ADFM firmware version number on
the first line and a hexadecimal-coded error map on the second line. The
software used to operate the ADFM will periodically report and reset the
error code map, and to re-run selected tests. By interpretation and further
fault isolation, it is possible to isolate a hardware problem to a least re-
placeable assembly (LRA) level. For a list of LRAs refer to
Table 4-1, page 4-6: List of Least Replaceable
2-4.1
Testing Interval
Routine execution of the built-in tests is not required during normal system
operation. Execution of selected built-in tests from software is recom-
mended quarterly or at each battery change, whichever is more frequent.
The built-in tests should also be performed whenever a hardware problem
with the ADFM is suspected. See
further details.
2-4.2
Test Record
The WinADFM software by default will create a log containing details of
all ADFM operations, including the status of the error code map and the re-
sults of all built-in tests. No further test record is required unless specifi-
cally requested by Technical Support Personnel.
