In many countries, the reproduction of copyrighted materials is not permitted, even if only for personal use, without the express prior consent of the copyright holder. Please check the current copyright laws for your country and comply with them. These restrictions do not apply, for example, to your own compositions and recordings, or for recordings for which authorization has been obtained from the copyright holder. MP3 playback You can play an MP3 CD on the CD changer* as you would any standard audio CD. All of the functions described for the CD changer also apply for the playback of MP3 CDs. Keep in mind that the single CD player in the audio system unit is not able to read MP3 CDs. The first 99 tracks on the CD, including tracks in subdirectories, are recognized and played. Any additional tracks will not be played. i Due to the branched data structure, playback of the first track may be delayed slightly. i Only use MP3 tracks with a bit rate of 128 kBit/s or higher and with the specified sampling rates. The use of rates other than those specified may lead to noticeably inferior sound quality. 219
