Troubleshooting

Appendix

Problem

When the instrument is turned on or off, a popping

sound is temporarily produced.

When using a mobile phone, noise is produced.

Noise is heard from the instrument's speakers or

headphones when using the instrument with the

application on iPhone/iPad/iPod touch.

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.

Not all of the voices seem to sound, or the sound

seems to be cut off.

Regardless of how strongly play the keys, the level

of the sound does not change.

The ACMP ON indicator does not appear when the

[ACMP ON/OFF] button is pressed.

The Style does not sound properly.

The Style does not sound as you play a chord.

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 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.

Power suddenly and unexpectedly turns off.

When the instrument is turned on, power is turned

off suddenly and unexpectedly.

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 interfer-

ence. To prevent this, turn off the mobile phone or use it further away from the

instrument.

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.

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.

When using the Dictionary function (page 21), the keys in the right hand area are

used only for entering the chord root and type.

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 "stolen")

from the accompaniment or Song.

Since this keyboard does not have touch response, the level of the sound does

not change in response to your playing strength.

• 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.

Make sure that the Style Volume (page 31 Function 001) is set to an appropriate

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 31 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 auto accompaniment will sometimes not change when related chords are

played in sequence (e.g., some minor chords followed by the minor seventh).

• Two-note fingerings will produce a chord based on the previously played chord.

• Playing two same root keys in the adjacent octaves produces accompaniment

based only on the root.

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 (sam-

ples) 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 batteries are low or dead. Replace all six batteries with completely new ones,

or use the included AC adaptor.

This is normal and the Auto Power Off function may have been activated (page

13). If you need to disable the Auto Power Off function, select "Off" in the Function

settings (Function 021; page 32).

This is normal. If an AC adaptor other than the one specified is used, power may

be turned off suddenly and unexpectedly.
