ENGLISH

•  Some CD-Rs or CD-RWs may not play 

back on this unit because of their disc 
characteristics, and for the following causes:

  – 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 
(stain, scratch, warp, 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 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 humidity may cause malfunctions or 
damages 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 ID3 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 (see page 11).

•  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)
    48 kHz, 44.1 kHz, 32 kHz (for WMA)
  – 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 recognize the total of 512 files, 

of 200 folders, and of 8 hierarchies.

•  This unit can play back the files recorded in 

VBR (variable bit rate).

  The files recorded in VBR have a discrepancy 

in elapsed time display, and do not show the 
actual elapsed time. This difference becomes 
noticeable especially after performing the 
search function.

•  This unit cannot play back the following files:
  – MP3 files encoded with MP3i and 

MP3 PRO format.

  – MP3 files encoded in an unappropriated 

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.
