XV (Main Board)
ESP4 (Main Board)
PPC (Main Board)
BA (Main Board)
DIMM (Main Board)
WAV BUS (Main Board)
HDD (Main Board)
CD-RW (Main Board)
MV8-VGA (Panel Board)
PS-2 (Panel Board)
DIMM (DIMM check) indicates the DIMM capacity (in MB units) and SPD
information.
HDD (hard disk check) and CD-RW (CD-RW drive check) will indicate the
model name of each drive.
MIDI CHECK
This checks the MIDI connectors.
* You will need one MIDI cable for this test.
Devices related to this test: (Main) IC35, IC37, IC38
1.
Use the MIDI cable to connect the MIDI OUT A connector to the MIDI IN
connector.
When MIDI messages sent from MIDI OUT A are correctly received at
MIDI IN, the indication at the right of "MIDI OUT A -> MIDI IN" will
change from "–" to "OK."
2.
Use the MIDI cable to connect the MIDI OUT B connector to the MIDI IN
connector.
When MIDI messages sent from MIDI OUT B are correctly received at
MIDI IN, the indication at the right of "MIDI OUT B -> MIDI IN" will
change from "–" to "OK."
LCD CHECK
This checks the LCD contrast adjustment, and the on/off operation of each
pixel.
Devices related to this test: (Main) IC17, IC23, LCD
The contrast adjustment screen will appear.
1.
Turn the CONTRAST knob and verify that you can distinguish the
gradations.
2.
Press [F5](NEXT).
All pixels will turn black.
3.
Press a button other than VELOCITY PADS.
All pixels will turn gray.
When you press a button other than VELOCITY PADS, you will proceed
to the next test item.

ENCODER CHECK
This checks whether the encoders are operating correctly.
Devices related to this test: (Panel) IC1
1.
Turn the VALUE dial 24 clicks toward the left.
The indication below "-" will change from "--" to "OK."
2.
Turn the VALUE dial 24 clicks toward the right.
The indication below "+" will change from "--" to "OK."
LED CHECK
This checks whether the LEDs are operating correctly.
Devices related to this test: (Panel) IC1
When you enter the LED CHECK screen, all LEDs will light.
1.
Press [PLAY].
All LEDs will go dark.
2.
Press [PLAY], and verify that the LEDs light consecutively one by one.
If you press [STOP], the LEDs will light consecutively one by one in the
opposite order as when you press [PLAY].
3.
With the LED above [REC] lit, press [PLAY] and verify that all LEDs
light.
SWITCH CHECK
This checks whether the switches are operating correctly.
Devices related to this test: (Panel) IC1
* Checking the operation of the VELOCITY PADS is done in the VELOCITY
PAD CHECK screen.
When you press a button on the panel, the switch you pressed will be shown
as a "black square" in the screen; switches you have not yet pressed are shown
as "white squares."
Press each switch one by one.
When you have finished pressing all switches, you will automatically proceed
to the next test item.
* If you press two or more switches at the same time, the screen will indicate
"More than one Sw pressed!."
If you want to abort SWITCH CHECK before completing it, turn the VALUE
dial more than one and a half rotations toward the left or right. If you turn it
toward the left, you will return to the previous test item. If you turn it toward
the right, you will proceed to the next test item.
A/D CHECK
This checks whether the volume controls are operating correctly.
Devices related to this test: (Panel) IC1
1.
Move the eight sliders "down" (minimum value)→"center"→"top"
(maximum value). When the minimum value and maximum value are
detected, the indications above and below the slider will change from "--"
to "OK."
2.
Turn the four volume knobs from "left" (minimum
value)→"center"→"right" (maximum value). When the minimum value
and maximum value are detected, the indications at the left and right of
the volume will change from "--" to "OK."
