61 MP3MP3 and WMA files have an "ID3tag/WMAtag" that allows input of text information so thatdata such as song title and artist can be saved.This unit supports ID3v.1.0 and ID3v.1.1 tags. Use only ASCII code to record tags, since onlyASCII code is supported by this equipment. Recording of characters not included in ASCIIcode will result in display of garbled characters.This unit supports the WMA tag (v1.20.02). Since the WMA tag supports unicode only,please input the information with unicode characters.Media capable of playing MP3/WMA includes CD-ROM, CD-R and CD-RW discs.Compared to CD-ROM media commonly used for music discs, CD-R and CD-RW discs arefragile in high temperature/high humidity environments and one section of the CD-R/CD-RWmay become incapable of playback. Fingerprints or scratches on the disc may preventplayback or cause skipping during playback.Sections of CD-R/CD-RW may deteriorate if left inside a vehicle for long periods of time.It is also recommended that CD-R/CD-RW discs be kept in a light-blocking case because thediscs are vulnerable to ultra-violet light.ID3tag/WMAtagMedia
