Playing a CD-R or CD-RW
• Use only "finalized" CD-Rs or CD-RWs.
• This unit can play back only files of the same type
which are first detected if a disc includes both audio
CD (CD-DA) files and MP3/WMA files.
• This unit can play back multi-session discs; however,
unclosed sessions will be skipped while playing.
• Some CD-Rs or CD-RWs may not play back on this
unit because of their disc characteristics, or for the
following reasons:
– Discs are dirty or scratched.
– Moisture condensation occurs on the lens inside
the unit.
– The pickup lens inside the unit is dirty.
– CD-R/CD-RW on which the files are written with
"Packet Write" method.
– There are improper recording conditions (missing
data, etc.) or media conditions (stained, scratched,
warped, etc.).
• CD-RWs may require a longer readout time since the
reflectance of CD-RWs is lower than that of regular
CDs.
• Do not use the following CD-Rs or CD-RWs:
– Discs with stickers, labels, or a protective seal stuck
to the surface.
– Discs on which labels can be directly printed by an
ink jet printer.
Using these discs under high temperatures or high
humidities may cause malfunctions or damage to the
unit.
Playing an MP3/WMA disc
• This unit can play back MP3/WMA files with the
extension code <.mp3> or <.wma> (regardless of
the letter case—upper/lower).
• This unit can show the names of albums, artists
(performer), and Tag (Version 1.0, 1.1, 2.2, 2.3, or
2.4) for MP3 files and for WMA files.
• This unit can display only one-byte characters. No
other characters can be correctly displayed.
• This unit can play back MP3/WMA files meeting the
conditions below:
– Bit rate: 8 kbps — 320 kbps
– Sampling frequency:
48 kHz, 44.1 kHz, 32 kHz (for MPEG-1)
24 kHz, 22.05 kHz, 16 kHz (for MPEG-2)
– Disc format: ISO 9660 Level 1/Level 2, Romeo,
Joliet, Windows long file name
• The maximum number of characters for file/folder
names vary among the disc format used (includes 4
extension characters—<.mp3> or <.wma>).
– ISO 9660 Level 1: up to 12 characters
– ISO 9660 Level 2: up to 31 characters
– Romeo: up to 128 characters
– Joliet: up to 64 characters
– Windows long file name: up to 128 characters
• This unit can play back files recorded in VBR (variable
bit rate).
Files recorded in VBR have a discrepancy in elapsed
time display, and do not show the actual elapsed
time. Especially, after performing the search function,
this difference becomes noticeable.
• This unit can recognize a total of 512 files, of 200
folders, and of 8 hierarchies.
• This unit cannot play back the following files:
– MP3 files encoded with MP3i and MP3 PRO format.
– MP3 files encoded in an inappropriate format.
– MP3 files encoded with Layer 1/2.
– WMA files encoded with lossless, professional, and
voice format.
– WMA files which are not based upon Windows
Media® Audio.
– WMA files copy-protected with DRM.
– Files which have the data such as AIFF, ATRAC3,
etc.
• The search function works but search speed is not
constant.
Changing the source
• If you change the source, playback also stops.
Next time you select "CD" for the playback source,
disc play starts from where it has been stopped
previously.
