Playing a CD If playing a CD-R the sound quality may be reduced due to CD-R quality, the method of recording, the quality of the music that has been recorded and the way the CD-R has been handled. You may experience an increase in skipping, difficulty in finding tracks and/or difficulty in loading and ejecting. If these problems occur try a known good CD. Do not add paper labels to CDs, they could get caught in the CD player. Do not play 3 inch (8 cm) CDs without a standard adapter disc.
