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

– 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 WAVE, 

ATRAC3, etc.

•  The search function works but search speed is 

not constant.
