SELF TEST
Available from Software 1.20 and up.
Accessing Self test
• Press and hold the “BYPASS” key, while
powering up to access the self test.
• Press PRESET 8 to increase test number.
• Press PRESET 4 to decrease test number.
• Press LOCK to enter a test and acknowledge
OK result.
• Press BYPASS to acknowledge bad result.
• The test number is shown in the OPTIMIZE
display. The self tests are described below.
Test 0 - LED test
Turns all LEDs on.
Test 1 - Analog In/Out test
Connect a balanced cable between ONE
analog Output and ONE analog Input.
The Input meter for the used Input should show
-12dB.
The symbol “+” will indicate that the test for the
used I/O is okay.
The symbol ”-” will indicate that the Input or
Output is not okay. If so, try the test with the
other analog Input/Output to narrow down the
problem.
Connect the cable to the other Output and Input
in order to test these.
Test 2 - AES/EBU In/Out test
Connect a balanced cable between AES/EBU
Input and Output.
The INPUT meters should show 0dB. The
symbol “+” will indicate that the test is okay.
The symbol ”-” will indicate that the Input or
Output is not okay.
Test 3 - S/PDIF In/Out test
Connect a RCA cable between S/PDIF Output
and Input.
The Input meters will show 0dB.
The symbol “+” will indicate that the test is
okay.
The symbol “-” will indicate that the Input or
Output is not okay.
Test 4 - RS232 remote I/O test
Connect Rx and Tx on the RS-232 connector
(pin no. 2 to pin no. 3).
The symbol “+” will indicate that the test is
okay. The symbol “-” will indicate that the Input
or Output is not okay.
Test 5 - GPI Input test
Connect a switch between the Tip and Sleeve
of the GPI Input jack.
When the switch is closed (tip is connected to
ground) the symbol “+” is shown, otherwise the
symbol “-” is shown.
Test 6 - Battery test
The battery voltage is tested and if within limits
the symbol “+” is shown, otherwise the symbol
“-” is shown.
Test 7 - System test
The ASIC, DSP, DSP RAM and EEPROM are
tested while "7" is flashing. If OK the symbol “+”
is shown, otherwise the symbol “-” is shown.
Test 8 - Ex.RAM test
The Ex.RAM memory board is tested during 1
minute while "8" is flashing.
If OK the symbol “+” is shown, otherwise the
symbol “-” is shown.
NB! This test is NOT implemented in
application software v. 1.01
