Appendix

The instrument does not turn on.
The instrument is automatically turned off even if
no operation is done.
Noise is heard from the speakers or head-
phones.
The overall volume is low, or no sound is heard.
The pedal has no effect.
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.

Problem
The instrument has not been plugged in properly. Securely insert the female plug into
the jack on the instrument, and the male plug into a proper AC outlet (page 7).
This is normal. This occurs due to the Auto Power Off function (page 19).
The noise may be due to interference caused by the use of a mobile phone in close
proximity to the instrument. Turn off the mobile phone, or use it further away from the
instrument.
The Master Volume is set too low; set it to an appropriate level using the [MASTER
VOLUME] slider (page 7).
Make sure a pair of headphones is not connected to the headphones jack (page 7).
Make sure that Local Control is ON. For details, refer to "MIDI Reference" (page 4) on
the website.
The pedal cable/plug may not be properly connected. Make sure to securely insert the
pedal plug into the [SUSTAIN] or [PEDAL UNIT] jack (page 8).
The polarity of the footswitch is reversed because the footswitch was pressed when the
power was turned on. Turn off the power and turn it on again to reset the function. Make
sure to not press the footswitch when turning the power on.
