cotton swab before wiping the ball.

Caring for Your
Computer
Follow these suggestions to protect your computer and monitor:
■
Operate the computer on a sturdy, level surface such as
a desk or table. Leave a three-inch (7.6-cm) clearance at
the back of the system unit and above the monitor to
permit required airflow.
■
Never restrict the airflow into the computer by blocking the
front vents or air intake. Do not place the keyboard, with the
keyboard feet down, directly against the front of the unit as
this will restrict the airflow.
■
Keep the computer away from excessive moisture, direct
sunlight, and extremes of heat and cold. For information
about the recommended temperature and humidity ranges
for your computer, refer to Appendix B, “Specifications.”
■
Keep liquids away from the computer and keyboard.
■
Never cover the ventilation slots on the monitor with any
type of material.
