Troubleshooting
Problem Possible Cause and Solution
When the instrument is turned on after pressing the
[ ] (Standby/On) switch, a popping sound is tempo-
rarily produced.
This is normal and indicates that the instrument is receiving elec-
trical power. When turning on the power, turn the [MASTER VOL-
UME] all the way down.
When the instrument is turned on after pressing the
[ ] (Standby/On) switch, power is turned off suddenly
and unexpectedly.
If an AC adaptor other than the one specified is used, power might
be turned off suddenly and unexpectedly. Use only the specified
AC adaptor (page 72).
When using a mobile phone, noise is produced in the
instrument’s speakers and/or headphones.
Using a mobile phone in close proximity to the instrument might
produce interference. To prevent this, turn off the mobile phone or
use it further away from the instrument.
The instrument automatically turns off even when no
operation is performed.
This is normal. This occurs due to the Auto Power Off function
(page 18).
• The volume is too low.
• The sound quality is poor.
• The Style/Groove/Song/Arpeggio stops unexpect-
edly or will not play.
• The recorded data of the song, etc. does not play cor-
rectly.
• The LCD display suddenly goes dark, and all panel
settings are reset.
• The instrument turns off when a USB flash drive is
connected.
The battery power is low or empty. Replace all the batteries with
completely new ones or completely recharged ones, or use the
AC adaptor.
No sound is produced even when the keyboard is
played, or when a Song, Style, or Groove is played
back.
Check if a set of headphones is connected to the [PHONES] jack.
Either unplug the headphones, or set Function 079 “Speakers”
(page 66) to “2 (SP On).”
Function 079 “Speakers” (page 66) is set to “3 (SP Off).” Set it to
either “1 (HPSwitch)” or “2 (SP On).”
Function 062 “Local Control” (page 65) is set to OFF. Normally,
this parameter should be set to ON.
The footswitch (for sustain) seems to produce the oppo-
site effect.
For example, pressing the footswitch cuts off the sound
and releasing it sustains the sounds.
This happens either because you were stepping on the footswitch
while turning the power on, or the footswitch was connected/dis-
connected while the power is on. Turn off the power, and then turn
it on again while being careful not to step on the footswitch.
Not all of the Voices seem to sound when playing the
keyboard, or the sound seems to be cut off when play-
ing Arpeggio, Style, Song, Groove Creator or the
QUICK SAMPLING pads.
You have exceeded 64 simultaneous notes, which is the maxi-
mum polyphony (the maximum amount of notes that can be
played simultaneously) of this instrument. If the Main, Dual, and
Split Voices are being used along with playback of Arpeggio,
Style, Groove or Song, some notes/sounds may be omitted (or
“stolen”).
The sound of the Voice changes from note to note. This is normal. The tone generation method uses multiple record-
ings (samples) of an instrument across the range of the keyboard;
thus, the actual sound of the Voice may be slightly different from
note to note.
The keyboard performance and playback of Style/Song/
Groove Creator produces an unexpected or inappropri-
ate sound, and cannot be restored to the normal status.
An unintended setting was made due to operation of the LIVE
CONTROL knob. To undo this, reset the panel settings by turning
off DSP2, changing the Voice, Style, Song or Groove Creator, or
pressing the [PORTABLE GRAND] button.
The Style, Song or Groove Creator does not start even
when the [START/STOP] button is pressed. The Arpeg-
gio does not start even when the note is pressed with
the Arpeggio turned on.
Function 063 “External Clock” (page 65) is set to ON. Normally,
this parameter should be set to OFF.
The volume of the Style, Song or Groove Creator is too
low.
Check the volume setting for each function (page 63).
The chords played in the left-hand area cannot be rec-
ognized even when ACMP is turned on.
The setting for Function 004 “Split Point” (page 62) is not correct.
Set it to an appropriate value.
