The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs
and the smaller CDs are loaded in the same
manner.If playing a CD-R, the sound quality can be

recording, the quality of the music that has been
recorded, and the way the CD-R has been
handled. There can be an increase in skipping,
difficulty in nding tracks, and/or difficulty in loading
and ejecting. If these problems occur, check the
bottom surface of the CD. If the surface of the CD
is damaged, such as cracked, broken, or
scratched, the CD will not play properly. If the
surface of the CD is soiled, seeCare of Your CDs
and DVDs on page 370for more information.

or an attempt is made to play scratched or
damaged CDs, the CD player could be
damaged. While using the CD player, use only

load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.
