Test
LCD display Test description, judging conditions, etc.
No.
011 011: SW, LED Chk Every time each switch is pressed, confirm the following test items.
• The corresponding pitch sound is output normally.
• “On” is displayed on the LCD.
• No key stick is existed.
• Confirm the LEDs light one by one.
When the test is finished, “End” is displayed on the LCD.
(OK: “[***] 0n” / NG: “NG:O=xxxx([***]) X=xxxx([***])”,
If multiple switches are pressed together: “Over Two Sw”)
(*** = Panel switch name)
If the [EXIT] switch is pressed twice, this inspection is cancelled
and return to the test item selection mode.
012 012: All LED On Checks all LEDs on the panel.
All the LEDs light together. Confirm all the panel LEDs light normally.
013 Red LED On Checks all the red LEDs on the panel.
All the red LEDs light together. Confirm all the lighting LEDs are red.
014 014: Green LED On Checks all the green LEDs on the panel.
All the green LEDs light together. Confirm all the lighting LEDs are green.
015 015: All LCD On Chk Checks all dots of LCD.
All dots of LCD are turned on.
Confirm the whole LCD screen becomes white.
016 016: All LCD Off Chk Checks all dots of LCD.
All dots of LCD are turned off.
Confirm the whole LCD screen becomes blue.
017 017: LCD Contrast Chk Checks LCD Contrast.
Adjust the contrast by pressing [DEC/NO] (to lighten) and [INC/YES] (to darken) buttons.
Confirm the contrast changes in 8 stages.
018 018: Encoder Chk Checks the encoders.
Turn the encoder clockwise, with increasing count number up to “+8”.
Then turn it counterclockwise, with decreasing count number down to “-8”.
Confirm the encoder moves smoothly.
Thereby “OK” is displayed for the encoder.
After executing the test, confirm that “OK” is displayed on the LCD.
(OK: “OK”)
019 019: Pitch Bend Chk Checks the pitch bend wheel.
Rotate the pitch bend wheel up to maximum, and the C3 note is output.
Then, rotate the wheel down to minimum, and the G3 note is output.
Finally, rotate the wheel to the center position, and the C4 note is output.
Confirm the wheel moves smoothly.
(“PitchBendUp:yy”, “PitchBendDown:yy”, “PitchBendCenter:yy”) / yy = Current value
After executing the test, confirm that “OK” is displayed on the LCD.
(OK: “OK”)
020 019: Pitch Bend Chk Checks the modulation wheel.
Rotate the modulation wheel up to maximum, and the C3 note is output.
Then, rotate the wheel down to minimum, and the G3 note is output.
Confirm the wheel moves smoothly.
After executing the test, confirm that “OK” is displayed on the LCD.
(“ModWheelUp:yy”, “ModWheelDown:yy”) / yy = Current value
(OK: “OK”)
021 021: Volume Chk Checks the volume knobs
Turn a volume counterclockwise, with decreasing count number down to “0”.
Then turn it clockwise, with increasing count number up to “127”.
Then turn it counterclockwise, with decreasing count number down to “64”.
Thereby “OK” is displayed for the volume.
Execute the above procedures for all the volumes one by one.
The order of inspection is not constrained.
Confirm each volume moves smoothly.
After executing the test, confirm that “OK” is displayed on the LCD.
(Indication for each volume: “<xx>yy”) / xx = Target value, yy = Current value
(OK: “OK”)
