Then, while pressing the three lower left buttons in the RHYTHM
GROUP section (SOUL & DISCO, GOSPEL & BLUES,
COUNTRY & WESTERN) at the same time, turn the POWER
button on again. (Note that, in this case, all programmable
settings, functions and memories return to their factory-preset
status.)
No sound is produced when the keys are pressed.

The MAIN VOLUME is at the minimum setting. Adjust the
volume with the MAIN VOLUME control.

The volumes for the selected parts are set to the minimum
levels. Use the balance buttons to set the volumes of the
relevant parts to appropriate levels.

The LOCAL CONTROL for a part performed on the keyboard
is set to OFF. Set the LOCAL CONTROL to ON.
Only percussive instrument sounds are produced when
the keyboard is played.

The sound you hear is different from the sound you
selected.

This sometimes occurs when you play back SEQUENCER or
COMPOSER data which was created on a different model, or
when MIDI data is received from a connected instrument. Select
the desired sounds again.
The sustain does not work even when the sustain pedal
is depressed.
•
The sustain pedal is not connected. Connect the pedal cord
firmly to the PEDAL IN terminal on the back of the instrument.
The sostenuto pedal and soft pedal do not operate
properly. For example, when the soft pedal is
depressed, the rhythm starts or a fill-in is played.

Different functions can be programmed in these pedals. You
can return the pedals to their original functions by turning off
the instrument once, or by using the PEDAL SETTING mode.

the RHYTHM part.
