Beware of the following:
❑ Do not strike or shake the computer while writing data to a disc.
❑ Memory-resident disc utilities, such as the screen saver and virus checker,
may cause unstable operation or data loss. Deactivate these utilities (if
they are active) before writing data to a disc.
❑ Always use the AC adapter as the power source for your computer when
you are writing data to a CD-RW or CD-R. Using battery power may result
in data transfer failure.
