21.2 Self test failures
Any failure during power-on self test (P.O.S.T.) is indicated on-screen and further
use of the instrument is denied. Try the following steps to resolve the failure:
1) To access Self test, press <Setup>, then highlight and <PICK> [Self test].
2) If you received a Max out/in or a Routing failure, remove any hearing aids from
the test chamber, unplug the monitor headphones (if used) and rerun self test.
3) Check that the cables from the rear display unit to the test chamber and that
the HIT reference microphone are firmly plugged in. Rerun self test.
4) Unplug all microphones (REM & HIT) from the test chamber. Rerun self test. If
self test passes, reconnect the microphones, one by one, running self test
each time until a failure occurs. If the failure returns, display and print the test
results and contact Audioscan for help.
