Notes on playing a CD-R or CD-RW: The built-in CD Recorder can play back both finalized and unfinalized CD-Rs/CD-RWs, however 3-CD Changer cannot play back unfinalized CD-RWs. Either on 3-CD Changer or on CD Recorder, you can play back CD-Rs or CD-RWs recorded on a personal computer only if they have been recorded in the CD audio format. Also 3-CD Changer can play back CD-Rs/CD-RWs (single session) including MP3 tracks (files). Some CD-Rs and CD-RWs may not be played back either on 3-CD Changer or on CD Recorder because of their disc characteristics, damage or stains. Important notice: Continuous use of irregularshaped discs (heart-shape, octagonal, etc.) can damage the disc rotating mechanism. CD-RWs may require a longer read-out time. This is caused by the fact that the reflectance of CD-RWs is lower than for regular CDs. MP3 discs require a longer read-out time. It differs depending on the complexity of the group/track configuration.
