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.

) E-25

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.
