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
