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
restricts airflow.
Never operate the computer with any of the access panels or any of the expansion card slot covers
●
removed.
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
●
sleep states.
To clean the computer, first turn off the computer.
●
● Disconnect AC power.
● Disconnect all powered external devices.
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.
● In addition to the standard care guidelines, to clean the healthcare model, use any of the following
germicidal wipe formulations to clean all exposed surfaces of the computer. Start with the display
and finish with any flexible cables. Allow the computer to air-dry before use. (For more
information, see the directions provided by the manufacturer of the wipes.)
IMPORTANT:
thinner, or any volatile substance to clean the display screen or cabinet. These chemicals may
damage the display.
