Troubleshooting
Problem Possible Cause and Solution
When the instrument is turned on or off, a popping
sound is temporarily produced.
This is normal and indicates that the instrument is receiving electrical power.
When using a mobile phone, noise is produced. Using a mobile phone in close proximity to the instrument may produce inter-
ference. To prevent this, turn off the mobile phone or use it further away from
the instrument.
There is no sound even when the keyboard is played or
when a song or style is being played back.
Check that nothing is connected to the PHONES/OUTPUT jack on the rear
panel. When a set of headphones is plugged into this jack, no sound is output.
Check the Local Control on/off. (See page 29 Function 015.)
Not all of the voices seem to sound, or the sound seems
to be cut off.
The instrument is polyphonic up to a maximum of 32 notes. If a style or Song
is playing back at the same time, some notes/sounds may be omitted (or “sto-
len”) from the accompaniment or Song.
Playing keys in the right hand area of the keyboard does
not produce any sound.
When using the Dictionary function (page 20), the keys in the right hand area
are used only for entering the chord root and type.
The Style or Song does not play back when the [START/
STOP] button is pressed.
Is External Clock set to ON? Make sure External Clock is set to OFF; refer to
“Function Settings” on page 29 (Function 016).
The ACMP ON indicator does not appear when the
[ACMP ON/OFF] button is pressed.
Always press the [STYLE] button first when you are going to use any style-
related function.
The Style does not sound properly.
Make sure that the Style Volume (page 29 Function 001) is set to an appropri-
ate level.
Is the Split Point set at an appropriate key for the cords you are playing? Set
the Split Point at an appropriate key (page 29 Function 005).
Is the “ACMP ON” indicator showing in the display? If it is not showing press
the [ACMP ON/OFF] button so that it does show.
• The auto accompaniment will sometimes not change when related chords
are played in sequence (e.g. some minor chords followed by the minor sev-
enth).
• Two-note fingerings will produce a chord based on the previously played
chord.
• Playing two same root keys in the adjacent octaves produces accompani-
ment based only on the root.
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.
The polarity of the footswitch is reversed. Make sure that the footswitch plug is
properly connected to the SUSTAIN jack before turning on the power.
Regardless of how strongly play the keys, the level of
the sound does not change.
Since this keyboard does not have touch response, the level of the sound
does not change in response to your playing strength.
• The volume is too soft.
• The sound quality is poor.
• The rhythm stops unexpectedly or will not play.
• The Song, etc. does not play correctly.
The batteries are low or dead. Replace all six batteries with completely new
ones, or use the optional AC adaptor.
Power suddenly and unexpectedly turns off. This is normal and the Auto Power Off function may have been activated
(page 9). If you need to disable the Auto Power Off function, select “Off” in the
Function settings (page 30 Function 024).
