ENGLISH
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 be played
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 (72) characters
– Joliet*: up to 64 (36) characters
– Windows long file name*: up to 128 (72)
characters
* The parenthetic figure is the maximum
number of characters for file/folder names in
case the total number of files and folders is
313 or more.
• 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 WAVE,
ATRAC3, etc.
• The search function works but search speed is
not constant.
