• Playing back these discs generates noise and
may damage the speakers.
• Damaged discs and discs with an unusual shape
(other than a disc of 12 cm or 8 cm in diameter)
cannot be played back.
• JVC does not guarantee the operation and
sound quality of discs not authorized by CD-DA,
which is a CD specification.
Before playback, confirm that the disc complies
with this CD specification by checking the sym-
bols and reading notes printed on the package.

• A disc may not be played back, or reading it may
take a long time depending on its recording con-
ditions or properties.
• The time needed for reading varies with the
number of groups or tracks (files) recorded on
the disc.
• If characters other than single-byte alphanu-
meric characters are used in the file name of an

file name is not displayed correctly.

MP3, WMA or WAV menu screen, and the order
of files/groups displayed on the JPEG menu
screen may be different from that of files/folders

time is not displayed until playback starts. This
elapsed time may not be displayed correctly.
• When playing back an MP3 or WMA file, a disc
