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.
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-26
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.
