Using CD-ROM Discs

and Trays

YOUR TASK:

Learn how to handle, load, and care for your discs.

YOUR OBJECTIVE:

Protect your discs. Insert and eject discs properly so
your drive operates without interruption.

YOUR METHOD:

Practice loading discs into trays.

Tray Loading and Operating

1)  While the drive is powered up, push the Eject button. The tray drawer will

slide out in 2--3 seconds.

2)  Press the Eject button again and the tray will slide shut within 2--3 seconds.

Note:

 We recommend you use the Eject button to close the tray in a smooth

and secure manner. Closing the tray by pressing the front of the drawer by
hand is not recommended.

Cleaning the Disc

If the disc is merely dusty, you may use a commercially available dust removal spray
such as Dust-Off or Vari-Air to blow dust particles off the disc.

After removing the dust particles, you may wipe the disc using a clean, soft cotton
cloth. Use a straight-line motion, wiping 

from the center out.

 Do 

not 

wipe the disc

in a circular motion.
