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.

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.
