•  This unit can play back MP3/WMA files meeting the 

conditions below:

  Bit rate of MP3/WMA: 5 kbps — 320 kbps
  Sampling frequency of MP3:
  –  48 kHz, 44.1 kHz, 32 kHz (for MPEG-1)
  –  24 kHz, 22.05 kHz, 16 kHz (for MPEG-2)
  Sampling frequency of WMA: 8 kHz — 48 kHz
•  The maximum number of characters for file/folder 

names is 25 characters (including <.mp3>, 
<.wma>); 128 characters for MP3/WMA Tag.

•  This unit can recognize a total of 20 000 files and 

2 000 folders (999 files per folder). However, the 
display can show until 999 folders/files.

•  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.
•  The search function works but search speed is not 

constant.

Playing MP3/WMA/WAV tracks from a USB 
device

•  Connecting a USB device automatically changes the 

source to “

USB FRONT/USB REAR

.”

•  While playing from a USB device, the playback order 

may differ from the one from other players.

•  This unit may be unable to play back some USB 

devices or some files due to their characteristics or 
recording conditions.

Playing a CD-R or CD-RW

•  Use only “finalized” CD-Rs or CD-RWs.
•  This unit can only play back files of the same type as 

those which are detected first 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 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 show WMA Tag.
