section for further detail.
Playing a CD
Insert a CD partway into the slot, label side up. The
player pulls it in and the CD should begin playing. If you
want to insert a CD with the ignition off, rst press the
Z(eject) button or the DISP knob.
If the ignition or radio is turned off with a CD in the
player it stays in the player. When the ignition or radio
is turned on, the CD starts to play where it stopped, if it
was the last selected audio source.When the CD is inserted, the CD symbol displays. As
each new track starts to play, the track number 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.
Care of Your CDs
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. Handle them carefully.
Store CD-R(s) in their original cases or other protective
cases and away from direct sunlight and dust. The
CD player scans the bottom surface of the disc. If the
surface of a CD is damaged, such as cracked, broken,
or scratched, the CD does not play properly or not
at all. Do not touch the bottom side of a CD while
handling it; this could damage the surface. Pick up CDs
by grasping the outer edges or the edge of the hole
and the outer edge.
If the surface of a CD is soiled, take a soft, lint free cloth
or dampen a clean, soft cloth in a mild, neutral detergent
solution mixed with water, and clean it. Make sure the
wiping process starts from the center to the edge.
