(without ejecting the disc).
Next time you select "DISC" for the playback
source, disc play starts from where it has been
stopped previously.
Ejecting a disc
• If the ejected disc is not removed within
15 seconds, the disc is automatically inserted
again into the loading slot to protect it from
dust. (Disc will not play this time.)
