For the Instrument
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
When using a mobile phone, noise is produced. Using a mobile phone in close proximity to the instrument may produce
interference. 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
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 98.)
Is the FILE CONTROL display showing? The instrument’s keyboard,
etc., will not produce any sound while the FILE CONTROL display is
showing. Press the [EXIT] button to return to the MAIN display.
Playing keys in the right hand area of the keyboard
does not produce any sound.
When using the Dictionary function (page 82), 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 “External Clock” on page 98.
The style does not sound properly. Make sure that the Style Volume (page 79) is set to an appropriate level.
Is the split point set at an appropriate key for the chords you are playing?
Set the split point at an appropriate key (page 80).
Is the “ACMP” indicator showing in the display? If it is not showing press
the [ACMP ON/OFF] button so that it does show.
No rhythm accompaniment plays when the [START/
STOP] button is pressed after selecting style num-
ber 136 or a style between 148–165 (Pianist).
This is not a malfunction. Style number 136 and style numbers 148–165
(Pianist) have no rhythm parts, so no rhythm will play. The other parts
will begin playing when you play a chord in the accompaniment range of
the keyboard if style playback is turned on.
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 64 notes. If the Dual
voice or Split voice is being used and a style or song is playing back at
the same time, some notes/sounds may be omitted (or “stolen”) from the
accompaniment or song.
The footswitch (for sustain) seems to produce the
opposite effect. For example, pressing the foot-
switch 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
The sound of the voice changes from note to note. This is normal. The AWM 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.
There are Japanese characters in the display mes-
Make sure the Language setting in the FUNCTION display is set to Eng-
lish. (See page 71)
The appropriate display does not appear when the
[VOICE] button is pressed.

the MAIN display, and then pressing one of the mentioned buttons.

Perhaps the performance assistant technology is turned on.
Press the [P.A.T. ON/OFF] button to turn it off.
The ACMP 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 “OverCurrent” message is shown in the upper
area of the MAIN display and the USB device does
not respond.
Communication with the USB device has been shut down because of
the overcurrent to the USB device. Disconnect the device from the USB
TO DEVICE terminal, then turn on the power of the instrument.
