Additional Information
• If you insert a CD-RW disc into this unit, time to playback will be longer than when
you insert a conventional CD or CD-R disc.
• Read the precautions with CD-R/CD-RW discs before using them.
MP3, WMA and WAV files
• MP3 is short for MPEG Audio Layer 3 and refers to an audio compression
technology standard.
• WMA is short for Windows Media™ Audio and refers to an audio compression
technology that is developed by Microsoft Corporation. WMA data can be encoded
by using Windows Media Player version 7 or later.
• WAV is short for waveform. It is a standard audio file format for Windows
• This unit may not operate correctly depending on the application used to encode
WMA files.
• Depending on the version of Windows Media Player used to encode WMA files,
album names and other text information may not be correctly displayed.
• There may be a slight delay when starting playback of WMA files encoded with
image data.
• This unit allows playback of MP3/WMA/WAV files on CD-ROM, CD-R and CD-RW
discs. Disc recordings compatible with level 1 and level 2 of ISO9660 and with the
Romeo and Joliet file system can be played back.
• It is possible to play back multi-session compatible recorded discs.
• MP3/WMA/WAV files are not compatible with packet write data transfer.
• The maximum number of characters which can be displayed for a file name,
including the extension (.mp3, .wma or .wav), is 64, from the first character.
• The maximum number of characters which can be displayed for a folder name is 64.
• In case of files recorded according to the Romeo file system, only the first 64
characters can be displayed.
• When playing discs with MP3/WMA/WAV files and audio data (CD-DA) such as CD-
EXTRA and MIXED-MODE CDs, both types can be played only by switching mode
between MP3/WMA/WAV and CD-DA.
• The folder selection sequence for playback and other operations becomes the
writing sequence used by the writing software. For this reason, the expected
sequence at the time of playback may not coincide with the actual playback
sequence. However, there also is some writing software which permits setting of the
playback order.
• Some audio CDs contain tracks that merge into one another without a pause. When
these discs are converted to MP3/WMA/WAV files and burned to a CD-R/CD-RW/
CD-ROM, the files will be played back on this player with a short pause between
each one, regardless of the length of the pause between tracks on the original audio
CD.
Important
• When naming an MP3/WMA/WAV file, add the corresponding filename extension
(.mp3, .wma or .wav).
• This unit plays back files with the filename extension (.mp3, .wma or .wav) as an
MP3/WMA/WAV file. To prevent noise and malfunctions, do not use these
extensions for files other than MP3/WMA/WAV files.
