Possible cause

• CD-R/RW written format is out of specification

• MP3/WMA and other format data are in the CD-R/RW

• File extension for MP3/WMA-formatted file is incorrect (Correct. “.mp3”/“.wma”, incorrect: e.g., RIFF)

• Defective CD-R/RW (e.g. dirty CD, scratch)

• Audio unit malfunction

NOTE:

• The free-software for the MP3/WMA-formatted file in the field may cause the deterioration of sound quality, noise, or defective play, so that the CD player won’t play the customer made MP3/WMA-formatted file.

• The CD player may not play the CD-R/RW properly due to the disc condition.

• If there are MP3/WMA-formatted file and other file in the same disc, the CD player may not play the disc.

• If there are MP3/WMA-formatted file and audio data in the same disc, the CD player loads and plays the first session of the data only.
