■ 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
power.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the instrument may pro-
duce 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
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 106.)
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 87), 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 106.
The style does not sound properly.
Make sure that the Style Volume (page 93) is set to an appropriate
level.
Is the split point set at an appropriate key for the chords you are play-
ing? Set the split point at an appropriate key (page 82).
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 number 131 or a style between 143–160
(Pianist).
This is not a malfunction. Style number 131 and style numbers 143–
160 (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 “sto-
len”) 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 foot-
switch 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 key-
board; thus, the actual sound of the voice may be slightly different
from note to note.
The Demo display is shown in Japanese, and/or
there are Japanese characters in the display mes-
sages.
Make sure the Language setting in the FUNCTION display is set to
English. (See page 18)
