LOCATION OF CUSTOMER CONTROLS

1. Disc tray

This is the tray for the disc. Place the disc on the
ejected disc tray, then lightly push the tray (or
push the eject button) and the CD will be loaded.

NOTE: Don’t pull out or push in the disc tray
forcibly. This might cause damage to the loading
section of the drive.

2. Eject button

This button is pressed to open the CD tray.
This button works only when power is supplied to
the drive.

3. Emergency Eject Hole

Insert a paper clip here to eject the Disc tray
manually or when there is no power.

4. Drive activity indicator

Green colored LED is used to indicate the
operation of Super Multi DVD Drive.
