Skipping Test Items
• SHIFT + CURSOR : This performs forced movement to the next
test item.
• SHIFT + CURSOR : This performs forced movement to the
previous test item.
• SHIFT + EXIT: This forces execution to return to 1. VERSION
CHECK.
* After one of the operations just described has been performed, the screen remains
unchanged for 1 to 2 seconds. Press only once, and not multiple times.

1. VERSION CHECK
This verifies the version of the main program.
fig.screen001.eps
Press CURSOR to advance to the next test item.
2. DEVICE 1
This automatically tests various devices.
fig.screen002.eps
Press ENTER to start the test.
If all results are OK (acceptable), execution automatically advances to the
next test item.
If a problem is found, NG (not OK) appears, and at the same time, the
location of the problem is displayed. (No automatic advance to the next
item occurs.)
3. DEVICE 2
This verifies audio input and output as well as USB and MIDI operation.

Verification of Audio Input and Output
(Sampling Rate: 44.1 kHz)
This verifies the signals output from the PHONES and A (MIX) L and R
(XLR) connectors.
1. Press PART .
The message Audio Routing : 1/2 is displayed.
2. Connect the oscilloscope to the PHONES connector.
3. Verify that signals like the following are output.
L: 1-kHz sine wave at 17.0 Vpp ±20%
R: 2-kHz sine wave at 17.0 Vpp ±20%
4. Turn the VOLUME control and verify that the signal level changes from
17.0 Vpp to 0 Vpp, and then to 17.0 Vpp.
5. Verify that the waveforms are muted (0 Vpp) while PART VIEW is
depressed.
6. Connect the oscilloscope to the A (MIX) L and R connectors (each XLR).
7. Verify that signals like the following are output.
L (HOT): 1-kHz sine wave at 7.7 Vpp ±10%
L (COLD): 1-kHz sine wave at 7.7 Vpp ±10%
R (HOT): 2-kHz sine wave at 7.7 Vpp ±10%
R (COLD): 2-kHz sine wave at 7.7 Vpp ±10%
8. Verify that the waveforms are muted (0 Vpp) while PART VIEW is
depressed.
