The instrument does not turn on.

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 10).

The instrument is automatically turned off even if 
no operation is done.

This is normal. This occurs due to the Auto Power Off function (page 10).

Noise is heard from the speakers or head-
phones.

The noise may be due to interference caused by the use of a mobile phone in close proxim-
ity to the instrument. Turn off the mobile phone, or use it further away from the instrument.

Noise can be heard coming from the digital 
piano’s built-in speakers and/or headphones 
when using it with an iPhone/iPad/iPod touch app.

In order to eliminate the risk of noise from other communication when using the instru-
ment with an iPad, iPhone, or iPod touch, we recommend turning on the device’s Air-
plane Mode.

The overall volume is low, or no sound is heard.

The Master Volume is set too low; set it to an appropriate level using the [MASTER 
VOLUME] (page 11).

The digital piano’s speakers are turned off. Turn them back on (page 23).

Make sure a pair of headphones or conversion adaptor is not connected to the head-
phones jack (page 11).

Make sure that Local Control is ON. For details, refer to “MIDI Reference” (page 8) on 
the website. 

Moving the [MASTER VOLUME] slider does not 
change the volume of the headphones.

Have you set the external speaker volume to “Fixed”?
Change the external speaker volume to “Variable.” (page 23)

The pedal has no effect.

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 12).

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 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.
