10. TIPS FOR OPERATING REAR SEAT ENTERTAINMENT SYSTEM
■ FILE NAMES
The only files that can be recognized as MP3/WMA/AAC and played are those with
the extension .mp3, .wma or .m4a.
■ MULTI-SESSIONS
As the audio system is compatible with multi-sessions, it is possible to play discs that
contain MP3, WMA and AAC files.
■ MP3, WMA AND AAC PLAYBACK
 When a disc containing MP3, WMA or AAC files is inserted, all files on the disc are first
checked. Once the file check is finished, the first MP3, WMA or AAC file is played. To
make the file check finish more quickly, we recommend you do not write inany files
other than MP3, WMA or AAC files or create any unnecessary folders.If the discs con-
tain a mixture of music data and MP3, WMA or AAC format data, only music data can
be played.
 To play MP3 files with steady sound quality, we recommend a fixed bit rate of 128 kbps
and a sampling frequency of 44.1 kHz.
 Playback may not be possible in some instances, depending on the characteristics of
the disc.
 There is a wide variety of freeware and other encoding software for MP3, WMA or
AAC files on the market, and depending on the status of the encoding and the file for-
mat, poor sound quality or noise at the start of playback may result. In some cases, play-
back may not be possible at all.
 When files other than MP3, WMA or AAC files are recorded on a disc, it may take
more time to recognize the disc and in some cases, playback may not be possible at all.

EXTENSIONS
If the file extensions .mp3, .wma and .m4a are used for files other than MP3, WMA and
AAC files, they will be mistakenly recognized and played as MP3, WMA and AAC
files. This may result in large amounts of interference and damage to the speakers.
