is not loaded
correctly in the
Digital Piano’s
memory card slot.

MUSICDAT
folder (page E-23)
on the memory
card.
2. There is no
loadable or
playable file in the
MUSICDAT
folder.
You are attempting
to save data to a
memory card when
there is no data to
save. The memory card is
write-protected. A read-only file
with the same name
you are trying to
use is already stored
on the memory
card. 1. There is not
enough room
available on the
memory card.
2. There is not
enough room
available in
Digital Piano
memory.
Action
1. Correctly load the
memory card into
the memory card
slot.
2. Do not remove
the memory card
while any
operation is in
progress.
1. Create a
MUSICDAT
folder on the
memory card or
format the
memory card on
the Digital Piano
(page E-22).
2. Move the file you
want to load or
play into the
memory card’s
MUSICDAT
folder.
Record something
before performing a
save operation. Use the memory
card’s write protect
switch to enable
writing. • Use a different
name to save the
new file.
• Remove the read-
only attribute
from the existing
file and overwrite
it with the new
file.
• Use a different
memory card.
1. Delete some of the
files on the
memory card to
make room for
new data (page
E-24), or use a
different card.
2. Delete some or all
user data from
Digital Piano
memory to make
room for new
data.
