General

•  This unit has been designed to reproduce CDs/CD 

Texts, and CD-Rs (Recordable)/CD-RWs (Rewritable) 
in audio CD (CD-DA), MP3/WMA/AAC formats.

•  When a disc is inserted upside down, “Please Eject” 

appears on the display. Press 

0

 to eject the disc.

•  While fast-forwarding or reversing on an MP3/WMA/

AAC disc, you can only hear intermittent sounds.

•  In this manual, words “track” and “file” are 

interchangeably used.

•  File/folder list may not appear correctly if too many 

hierarchies and folders are used.

•  If the ejected disc is not removed within 15 seconds, 

the disc is automatically inserted again into the 
loading slot to protect it from dust. Playback starts 
automatically.

•  After ejecting a disc or removing a USB device, 

“No Disc” or “No USB” appears and you cannot 
operate some of the buttons. Insert another disc, 
reattach a USB device, or press SRC to select another 
playback source.

•  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

  –  AAC files created by any other application than 

iTunes.

  –  AAC files encoded with Apple lossless format.
  –  Files which have the data such as AIFF, ATRAC3, 

etc.

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/AAC 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.
