When the CD is inserted, the CD symbol displays.
As each new track starts to play, the track number
also displays.
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 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. 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 302for
more information.
If there is no apparent damage, try a known
good CD.
Do not add any label to a CD, it could get
caught in the CD player. If a CD is recorded
on a personal computer and a description label
is needed, try labeling the top of the recorded
CD with a marking pen.
Notice:If a label is added to a CD, or more
than one CD is inserted into the slot at a time,
or an attempt is made to play scratched or
damaged CDs, the CD player could be
damaged. While using the CD player, use
only CDs in good condition without any label,
load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.
If an error displays, see “CD Messages” later
in this section.
