Troubleshooting hints
•  CD-R/RW written format is out of specification
•  MP3 and other format data are in the CD-R/RW
•  File extension for MP3-formatted file is incorrect (Correct. “.mp3”, incorrect: e.g., RIFF)
•  Defective CD-R/RW (e.g. dirty CD, scratch)
•  MP3 applicable CD player/changer is malfunctioning
Note
•  The free-software for the MP3-formatted file in the field may cause the deterioration of sound quality, noise, or defective play, so that the CD player/changer won’t play the customer made MP3-formatted file.
•  The CD player may not play the CD-R/RW properly due to the disc condition.
•  If there are MP-3-formatted file and other file in the same disc, the CD player/changer may not play the disc.
•  If there are MP-3-formatted file and audio data in the same disc, the CD player/changer loads and plays the first session of the data only.
