FDD Check
Display: OK/NG
Devices related to the test: Main:IC49,63,64, X5, FDD
* This test requires a formatted 2HD floppy disk.
Insert a formatted 2HD floppy disk beforehand, and a write/verify test will be
performed.
MV8-VGA Check
Display: OK/NG
Devices related to the test: Main:IC1, Panel:IC1, MV8-VGA
* This test requires the MV8-VGA.
If the MV8-VGA is correctly installed, the screen will indicate "OK".
If "NG" is shown even if the MV8-VGA is installed, check the MV8-VGA's
connector and wiring.
PS/2 Mouse Detect Check
Display: OK/NG
Devices related to the test: Panel:IC1, MV8-VGA
* This test requires the MV8-VGA and a PS/2 mouse.
The Device ID and Device Status of the PS/2 mouse will be obtained, and if
communication with the mouse could be established, a result of "OK" will
appear.
MIDI Connect Check
Display: OK/--
Devices related to the test: Main:IC35,37,38
* This test requires a MIDI cable.
1.
Use a MIDI cable to make a loop connection between MIDI OUT A <--->
MIDI IN.
If the messages sent from MIDI OUT A were correctly received at MIDI
IN, a result of "OK" will appear.
2.
Re-connect the MIDI cable to MIDI OUT B <---> MIDI IN.
If the messages sent from MIDI OUT B were correctly received at MIDI
IN, a result of "OK" will appear.
LCD Check
Display: OK/NG
Devices related to the test: Main:IC17,23, LCD
1.
A test pattern will be displayed. Turn the contrast adjustment knob, and
verify that the gradations can be distinguished.
2.
Press the [NEXT] (F5) button. All pixels of the LCD will turn "black."
3.
Next, press any button other than PAD. All pixels of the LCD will turn
"off."
4.
Press any button other than PAD to proceed to the next test.
Encoder Check
Display: OK/NG
Devices related to the test: Panel:IC1
Turn the rotary encoder to left and right. The "OK" result will appear when
you turn the encoder 24 clicks in each direction.
LED Check
Display: OK/NG
Devices related to the test: Panel:IC1
1.
Enter this screen and press the [PLAY] button. All LEDs will light. Press
the [PLAY] button once again, and they will all go dark.
2.
Press the [PLAY] button an additional time, and the LEDs will light one
by one in sequence.
3.
Press the [STOP] button, and the LEDs will light in the reverse order of
when you pressed the [PLAY] button.
4.
After the last LED has lit, press the [PLAY] button to return to the "all lit"
state.
Switch Check
Display: OK/NG
Devices related to the test: Panel:IC1
This checks the operation of all switches on the panel board.
1.
In the screen, switches that have not yet been pressed are shown as white
rectangles. When a switch has been pressed, its display will change to a
black rectangle.
2.
If you press two or more switches simultaneously, a warning of "More
than one Sw pressed!" will appear.
3.
When all switches have been checked, you will automatically proceed to
the next item.
4.
To execute this test and move to the next item, turn the encoder toward
the right for one and a half revolutions or more. To return to the
preceding item, turn the encoder toward the left for one and a half
revolutions or more.
A/D Check
Display: OK/NG
Devices related to the test: Panel:IC1
This tests the operation of the rotary volumes and sliders on the panel board.
1.
Move each knob or slider through the "MIN" --> "MAX" --> "MIN"
positions.
2.
If the movement was detected correctly, the display will indicate "OK."
