Operating your computer
To eject the drawer manually (for example, during a power
failure) you must first ensure that the computer is turned off.
Then insert a thin metal rod (such as an unwound paper clip)
into the emergency eject hole and push (see below).
Keep CDs well away from dust and moisture, and avoid
touching the surface of the CD. Also, avoid extremes of
temperature and exposure to direct sunlight.
CD caddy drives
A few CD-ROM drives need a CD caddy in order to play CDs.
To identify one of these drives compare your drive to the
illustration below.
