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.
Noise is heard from the instrument’s speakers or head-
phones when using the instrument with the application
on iPhone/iPad/iPod touch.
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.
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.
Playing keys in the right hand area of the keyboard does
not produce any sound.
When using the Dictionary function (page 21), the keys in the right hand area
are used only for entering the chord root and type.
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.
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 ACMP ON indicator does not appear when the Duo mode is on.
The Style does not sound properly. Make sure that the Style Volume (page 30 Function 001) is set to an appropri-
ate 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 30 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 Style does not sound as you play a chord. • 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.
The sound of the voice changes from note to note. This is normal. The AWM tone generation method uses multiple recordings
(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 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 cor-
rectly.
• The LCD display suddenly goes dark, and all panel
settings are reset.
The batteries are low or dead. Replace all six batteries with completely new
ones, or use the included AC adaptor.
Power suddenly and unexpectedly turns off. This is normal and the Auto Power Off function may have been activated
(page 14). If you need to disable the Auto Power Off function, select “Off” in
the Function settings (Function 022; page 31).
When the instrument is turned on, power is turned off
suddenly and unexpectedly.
This is normal. If an AC adaptor other than the one specified is used, power
may be turned off suddenly and unexpectedly.
