ENGLISH
• 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 has occurred on the
lens inside the unit.
– The pickup lens inside the unit is dirty.
– The files on the CD-R/CD-RW are written
using the “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 temperature
or high humidity 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:
MP3: 32 kbps — 320 kbps
WMA: 32 kbps — 192 kbps
– Sampling frequency of MP3:
32 kHz, 44.1 kHz, 48 kHz (for MPEG-1)
16 kHz, 22.05 kHz, 24 kHz (for MPEG-2)
– Sampling frequency of WMA:

etc.).
• This unit can recognize a total of 512 files, 255
folders, and 8 hierarchical levels.
• This unit can play back files recorded in VBR
(variable bit rate).
Files recorded in VBR have a discrepancy
in the elapsed time display, and do not
show the actual elapsed time. In particular,
this difference becomes noticeable after
performing the search function.
• This unit cannot play back the following files:
– MP3 files encoded in MP3i and MP3 PRO
format.
– MP3 files encoded in an inappropriate
format.
– MP3 files encoded with Layer 1/2.
– WMA files encoded in lossless, professional,
and voice format.
– WMA files which are not based upon
Windows Media ® Audio.
– WMA files copy-protected with DRM.
– Files which have data such as AIFF, ATRAC3,
etc.
