Troubleshooting
Problem | Cause | Action | See Page |
No sound is produced when I press a keyboard key. | 1. The VOLUME controller is set to “MIN”. 2. Headphones or an adaptor plug is plugged into one of the PHONES jacks. 3. MIDI Local control is turned off. |
1. Rotate the VOLUME controller more towards “MAX”. 2. Disconnect whatever is connected to the PHONES jacks. 3. Turn on the Local control setting. |

The pitch of the digital piano is off. | 1. The digital piano’s key setting is something other than “440.0Hz”. 2. Digital piano tuning is incorrect. 3. Octave shift is enabled. 4. A non-standard temperament setting is being used. |
1. Change the key setting to “440.0Hz”, or turn digital piano power off and then back on again. 2. Adjust digital piano tuning, or turn the digital piano off and then back on again. 3. Change the octave shift setting to 0. 4. Change the temperament setting to “00: Equal”, which is the standard modern tuning. |

Nothing happens when I press a pedal. | The pedal unit cable is not connected. | Connect the cable correctly. | E-41 |
Tones and/or effects sound strange. Turning power off and then back on again does not eliminate the problem. Example: Note intensity does not change even though I alter key pressure. |
The “Back up” feature is turned on. | Turn off “Back up”. Next, turn power off and then back on again. | E-25 |
I cannot transfer data after connecting the digital piano to a computer. | - | 1. Check to make sure that the USB cable is connected to the digital piano and computer, and that the correct device is selected with your computer’s music software. 2. Turn off the digital piano and then exit the music software on your computer. Next, turn the digital piano back on and then restart the music software on your computer. |

I cannot store data to a USB flash drive or load data from a USB flash drive. | - | See “Error Indicators”. | E-33 |
It takes a long time before I can use the Digital Piano after I turn it on. | Digital Piano memory data was corrupted because a data transfer operation with a computer was in progress the last time you turned off the piano. When this happens, the Digital Piano performs a memory format operation the next time you turn it on. You cannot perform any other operation while a format operation is in progress. | It takes about 20 seconds after you turn on power to perform the memory format operation. Wait until the format operation is complete. Note that you should take care to avoid turning off the Digital Piano while a data transfer operation with a computer is in progress. | E-36 |
A tone’s quality and volume sounds slightly different depending where it is played on the keyboard. | This is an unavoidable result of the digital sampling process,* and does not indicate malfunction. * Multiple digital samples are taken for the low range, middle range, and high range of the original musical instrument. Because of this, there may be very slight differences in tonal quality and volume between sample ranges. |

When I press a button, the note that is sounding cuts out momentarily or there is a slight change in how effects are applied. | This happens when the sounds of multiple parts are sounding at the same time while using layer, using the Duet Mode, playing back a built-in tune, recording, etc. Pressing a button when one of these conditions exists will cause the effect setting that is built into the tone to change automatically, which causes notes to cut out momentarily or causes a slight change in how effects are being applied. |
