Troubleshooting

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 produce inter-

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

the instrument.

Noise is heard from the instrument’s speakers or head-

phones when using the instrument with the application

on iPhone/iPad.

When you use the instrument along with the application on your iPhone/iPad,

we recommend that you set “Airplane Mode” to “ON” on your iPhone/iPad in

order to avoid noise caused by communication.

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 setting. (See page 25 Function 015.)

Playing keys in the right hand area of the keyboard does

not produce any sound.

When using the Dictionary function (page 19), the keys in the right hand area

are used only for entering the chord root and type.

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 32 notes. If 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 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

“Function Settings” on page 25 (Function 016).

The ACMP ON 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 Style does not sound properly. Make sure that the Style Volume (page 24 Function 001) is set to an appropri-

ate 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 24 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 Style does not sound as you play a chord. • The auto accompaniment will sometimes not change when related chords

are played in sequence (e.g., some minor chords followed by the minor sev-

enth).

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

chord.

• Playing two same root keys in the adjacent octaves produces accompani-

ment based only on the root.

The footswitch (for sustain) seems to produce the oppo-

site effect. For example, pressing the footswitch 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 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 keyboard; thus, the actual

sound of the voice may be slightly different 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 cor-

rectly.

• The LCD display suddenly goes dark, and all panel

settings are reset.

The batteries are low or dead. Replace all six batteries with completely new

ones, or use the optional AC adaptor.

Power suddenly and unexpectedly turns off. This is normal and the Auto Power Off function may have been activated

(page 12). If you need to disable the Auto Power Off function, select “Off” in

the Function settings (page 25 Function 024).
