Closing the Drawer
Push in the drawer until it closes completely. Do not press the eject button.
Note
The EJECT function offered by various applications for opening the
CD-ROM drawer does not work with this drive.
After the drawer has been closed, the CD is tested and the access display light on
the drive starts to flash:
– If the display flashes continually, the CD is faulty but can still be read,
– If the display flashes several times and then remains lit, the CD you have
inserted is defective and cannot be read.
– the access indicator light is normally lit when the CD is being read.
