Disc drive problems

If the disc tray fails to open normally, follow these steps:

2.Press in gently on the paper clip until the tray is released, and then pull out the tray (2) until it stops.

3.Remove the disc (3) from the tray by gently pressing down on the spindle while lifting the outer edges of the disc. Hold the disc by the edges and avoid touching the flat surfaces.

NOTE: If the tray is not fully accessible, tilt the disc carefully as you remove it.

4.Close the disc tray and place the disc in a protective case.
