Appendix

Problem
When the instrument is turned on or off, a popping
sound is temporarily produced.
When using a mobile phone, noise is produced.
Noise is heard from the instrument's speakers or
headphones when using the instrument with the
application on iPhone/iPad/iPod touch.
There is no sound even when the keyboard is played
or when a song or style is being played back.
Playing keys in the right hand area of the keyboard
does not produce any sound.
Not all of the voices seem to sound, or the sound
seems to be cut off.
Regardless of how strongly play the keys, the level
of the sound does not change.
The ACMP ON indicator does not appear when the
[ACMP ON/OFF] button is pressed.
The Style does not sound properly.
The Style does not sound as you play a chord.
The footswitch (for sustain) seems to produce the
opposite effect. For example, pressing the footswitch
cuts off the sound and releasing it sustains the
sounds.
The sound of the voice changes from note to note.
• The volume is too soft.
• The sound quality is poor.
• The rhythm stops unexpectedly or will not play.
• The recorded data of the song, etc. does not play
correctly.
• The LCD display suddenly goes dark, and all
panel settings are reset.
Power suddenly and unexpectedly turns off.
When the instrument is turned on, power is turned
off suddenly and unexpectedly.

Possible Cause and Solution
This is normal and indicates that the instrument is receiving electrical power.
Using a mobile phone in close proximity to the instrument may produce interfer-
ence. To prevent this, turn off the mobile phone or use it further away from the
instrument.
When you use the instrument along with the application on your iPhone/iPad/iPod
touch, we recommend that you set "Airplane Mode" to "ON" on your iPhone/iPad/
iPod touch in order to avoid noise caused by communication.
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.
When using the Dictionary function (page 21), the keys in the right hand area are
used only for entering the chord root and type.
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 "stolen")
from the accompaniment or Song.
Since this keyboard does not have touch response, the level of the sound does
not change in response to your playing strength.
• Always press the [STYLE] button first when you are going to use any Style-
related function.
• The ACMP ON indicator does not appear when the Duo mode is on.
Make sure that the Style Volume (page 31 Function 001) is set to an appropriate
level.
Is the Split Point set to an appropriate key for the chords you are playing? Set the
Split Point to an appropriate key (page 31 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 seventh).
• Two-note fingerings will produce a chord based on the previously played chord.
• Playing two same root keys in the adjacent octaves produces accompaniment
based only on the root.
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.
This is normal. The AWM tone generation method uses multiple recordings (sam-
ples) 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 batteries are low or dead. Replace all six batteries with completely new ones,
or use the included AC adaptor.
This is normal and the Auto Power Off function may have been activated (page
13). If you need to disable the Auto Power Off function, select "Off" in the Function
settings (Function 021; page 32).
This is normal. If an AC adaptor other than the one specified is used, power may
be turned off suddenly and unexpectedly.
