Troubleshooting
Notes don’t sound right
Pitch of the keyboard or
song is incorrect
Could you have made Key Control settings?
Keyboard volume is too low
Could the [BALANCE] knob be all the way toward “SONG”?
The wrong instrument is se-
lected when you press the
[SCAT], [CHOIR], or [VIBRA-
PHONE] button
The [SCAT], [CHOIR], and [VIBRAPHONE] buttons also function as buttons that
select “Recommended tones”.
If the Setup Menu item
appropriate for the song will automatically be assigned to these buttons, and can
be selected by pressing the corresponding button.
High-pitched ringing is heard
If you hear this in headphones:
Piano sounds that have a brilliant and crisp character contain substantial high-
frequency components that may sound as though a metallic ringing has been
added. This is because the character of an actual piano is being faithfully
reproduced, and is not a malfunction.
If you don’t hear this in headphones:
It is likely that there is some other reason (such as resonances within the unit).
Please contact your dealer or a nearby Roland service center.

The sounds of multiple in-
struments are heard when
you play the keyboard
Could you have pressed the [DRUMS] button so the keyboard is set to play drum
sounds?
If the [DRUMS] button is lit, the white keys C2--B3 will play drum sounds. The black
keys C#2--Bb3 will play sound effects, and keys C4--C7 will play the sound they
were playing before you pressed the [DRUMS] button.

Low notes sound wrong, or
are buzzy
If you don’t hear this in headphones:
Performing at high volumes may cause the speakers or objects near the piano to
resonate. Fluorescent lights or glass doors may also resonate sympathetically. In
particular, this is more likely to occur for lower notes and higher volumes. You can
take the following measures to minimize resonances.
• Locate the speakers 10--15 cm away from walls or other surfaces.
• Keep the volume down.
• Move away from the objects that are resonating.
If you hear this in headphones:
It is likely that there is some other reason. Please contact your dealer or a nearby
Roland service center.
