sound quality of discs not authorized by CD-DA,
which is CD specifications.
Before playback, confirm that the disc complies
with this CD specifications by checking the
marks and reading notes printed on the

• A disc may not be played back, or reading it may
take a long time depending on its recording
conditions 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
alphanumeric characters are used in the file
name of an MP3/WMA/WAV/JPEG/ASF file, the
track/file name is not displayed correctly.
• The order of tracks/groups displayed on the
MP3/WMA/WAV menu screen, and the order of
files/groups displayed on the JPEG menu screen
may be different from that of files/folders
displayed on a computer monitor screen.
• Playing back an MP3/WMA file that contains a
still image may take a long time. The elapsed
time is not displayed until playback starts. This
elapsed time may not be displayed correctly.

frequency of 44.1 kHz and transmission rate of
128 kbps is recommended.
