Computer operating guidelines and routine care
Follow these guidelines to properly set up and care for the computer and monitor:
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
Operate the computer on a sturdy, level surface. Leave a 10.2 cm (4 in) clearance on all vented sides of
the computer and above the monitor to permit the required airflow.
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
Never operate the computer with any of the access panels or any of the expansion card slot covers
Do not stack computers or place computers so near each other that they are subject to each other's
recirculated or preheated air.
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be
provided on the enclosure, and the same operating guidelines listed above will still apply.
Keep liquids away from the computer and keyboard.
Never cover the ventilation slots with any type of material.
Install or enable power management functions of the operating system or other software, including
Turn off the computer before you do any of the following:
Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products may
discolor or damage the finish.
Wipe the screen with a soft, clean antistatic cloth. For more difficult cleaning situations, use a
50/50 mix of water and Isopropyl alcohol. Spray the cleaner onto a cloth and use the damp cloth to
gently wipe the screen surface. Never spray the cleaner directly on the screen surface. It may run
behind the bezel and damage the electronics.
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign
matter can block the vents and limit the airflow.
Do not use cleaners that contain any petroleum based materials such as benzene, thinner, or any
volatile substance to clean the screen or cabinet. These chemicals may damage the computer.
Follow these suggestions when preparing to ship the computer:
Back up the hard drive files to an external storage device. Be sure that the backup media is not exposed
to electrical or magnetic impulses while stored or in transit.
