Troubleshooting

Appendix

Problem
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.
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.
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.

P-45 Owner's Manual
Possible Cause and Solution
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).
This is normal. This occurs due to the Auto Power Off function (page 10).
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.
In order to eliminate the risk of noise from other communication when using the instru-
ment with an iPhone, iPad, or iPod touch, we recommend turning on the device's Air-
plane Mode.
The Master Volume is set too low; set it to an appropriate level using the [MASTER
VOLUME] slider (page 11).
Make sure a pair of headphones or conversion adaptor is not connected to the head-
phones jack (page 11).
The pedal cable/plug may not be properly connected. Make sure to securely insert the
pedal plug into the [SUSTAIN] jack (page 11).
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.
