Playing a CD (Single CD Player)
Insert a CD partway into the slot, label side up. The
player pulls it in and the CD should begin playing.
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 playing where it
stopped, if it was the last selected audio source.
When a CD is inserted, CD and the CD symbol
appears on the display. As each new track starts to
play the track number appears on the display.
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 (and playback
performance) may be reduced due to the CD-R
quality, method of recording, the quality of
the music that has been recorded, and the way
the CD-R has been handled. For better playback
performance when home burning audio discs,
use brand named CD media showing the Compact
Disc™, and a burn rate no faster than 12X.
