Troubleshooting

Problem
When the instrument is turned on or off, a
popping sound is temporarily produced.
When using a mobile phone, noise is pro-
duced.
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.
• 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.
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 Style number 098–106 (Pianist).
Not all of the voices seem to sound, or the
sound seems to be cut off.
The footswitch (for sustain) seems to pro-
duce the opposite effect. For example, press-
ing the footswitch cuts off the sound and
releasing it sustains the sounds.
The sound of the voice changes from note to
note.
The ACMP ON indicator does not appear
when the [ACMP ON/OFF] button is pressed.
The harmony doesn't sound.
The part indications, such as Right, Left and
Both Hands, do not appear—even when
pressing the [R] or [L] buttons for the Lesson.
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
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 output.
Check the Local Control on/off. (See page 62.)
When using the Dictionary function (page 57), the keys in the right hand
area are used only for entering the chord root and type.
The batteries are low or dead. Replace all six batteries with completely
new ones, or use the optional AC adaptor.
Is External Clock set to ON? Make sure External Clock is set to OFF;
refer to "External Clock Settings" on page 63.
Make sure that the Style Volume (page 53) is set to an appropriate level.
Is the Split Point set at an appropriate key for the cords you are playing?
Set the Split Point at an appropriate key (page 46).
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.
This is not a malfunction. Style number 098–106 (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
auto accompaniment is turned on.
The instrument is polyphonic up to a maximum of 32 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 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 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.
Always press the [STYLE] button first when you are going to use any
style-related function.
The method of sounding the harmony effect (01–26) differs depending
on the selected type. For Types 01–05, turn the Auto Accompaniment on
and play it by pressing a chord in the auto accompaniment section of the
keyboard, then play some keys in the right-hand side to get the harmony
effect. For Types 06–26, turning the Auto Accompaniment on or off has
no effect. However, it is necessary to play two notes simultaneously for
Types 06–12.
Make sure that you are not pressing the [R] or [L] buttons while the Song
is playing. If you press one of the part buttons while playing the Song
and before starting the Lesson, these buttons serve to mute the corre-
sponding Song tracks. Stop the Song first, then select the desired part
and start the Lesson.
