Troubleshooting

Problem

When the instrument is turned on or off, a popping

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.

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

to be cut off.

Playing keys in the right hand area of the keyboard does

not produce any sound.

The Style or Song does not play back when the [START/

STOP] button is pressed.

The ACMP ON indicator does not appear when the

[ACMP ON/OFF] button is pressed.

The Style does not sound properly.

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.

Regardless of how strongly play the keys, the level of

the sound does not change.

• The volume is too soft.

• The sound quality is poor.

• The rhythm stops unexpectedly or will not play.

• The Song, etc. does not play correctly.

Power suddenly and unexpectedly turns off.

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 inter-

ference. 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 29 Function 015.)

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.

When using the Dictionary function (page 20), the keys in the right hand area

are used only for entering the chord root and type.

Is External Clock set to ON? Make sure External Clock is set to OFF; refer to

"Function Settings" on page 29 (Function 016).

Always press the [STYLE] button first when you are going to use any style-

related function.

Make sure that the Style Volume (page 29 Function 001) is set to an appropri-

ate 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 29 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 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 polarity of the footswitch is reversed. Make sure that the footswitch plug is

properly connected to the SUSTAIN jack before turning on the power.

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

does not change in response to your playing strength.

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

ones, or use the optional AC adaptor.

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

(page 9). If you need to disable the Auto Power Off function, select "Off" in the

Function settings (page 30 Function 024).
