Troubleshooting

Problem
Power suddenly and unexpectedly turns off.
When the instrument is turned on or off, a pop-
ping sound is temporarily produced.
When using a mobile phone, noise is produced.
There is no sound even when the keyboard is
played or when a song or style is being played
back.
The style or song does not play back when the
[START/STOP] button is pressed.
The style does not sound properly.
No rhythm accompaniment plays when the
[START/STOP] button is pressed after selecting
the BaroqueAir Style in the MOVIE & SHOW
category.
Not all of the voices seem to sound, or the
sound seems to be cut off.
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 Demo display is shown in Japanese, and/or
there are Japanese characters in the display
messages.
The ACMP indicator does not appear when the
[ACMP] button is pressed.
There is no harmony sound.
The "OVER CURRENT" message is shown and
the USB device does not respond.

Owner's Manual
Possible Cause and Solution
This is normal and the Auto Power Off function may have been activated
(page 10). If desired, disable the Auto Power Off function.
This is normal and indicates that the instrument is receiving electrical
power.
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.
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 out-
put.
Is "Local Control" set to ON? Make sure "Local Control" is set to ON in the
Function display.
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.
Is "External Clock" set to OFF? Make sure "External Clock" is set to OFF in
the Function display.
Make sure that the "Style Volume" is set to an appropriate level in the Func-
tion display.
Is the split point set at an appropriate key for the chords you are playing?
Set the split point at an appropriate key in the Function display.
Is the [ACMP] button lit? If it is not lit, press the [ACMP] button so it lights.
This is not a malfunction. The BaroqueAir Style does not have a Rhythm
part, so there is no rhythm sound for this Style. Also, this Style does not
have a Fill-In section. The other parts will begin playing when you play a
chord in the accompaniment.
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 accompani-
ment or Song.
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
(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.
Make sure the Language setting in the Function display is set to English.
(See page 12)
Always press the desired style category button first when you are going to
use any Style-related function.
The Harmony effects (01–26) behave differently according to their type.
Types 01–10 and 13 function when Style playback is on, chords are played
in the accompaniment range of the keyboard, and a melody is played in the
right-hand range. Types 15–26 will function whether Style playback is on or
off. For types 23–26 you need to play two notes at the same time.
Communication with the USB device has been shut down because of over-
current to the USB device. Disconnect the device from the USB TO DEVICE
terminal, then turn the power of the instrument off and on again.
