20.2 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, and rerun self test.
3) Unplug all microphones (REM & HIT). 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.
