5.3 Operating Guidelines

To prevent overheating and to help prolong the life of the computer:

■ 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-inch) 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.

■ 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.

■ Never operate the computer with the cover or side panel removed.

■ Do not stack computers on top of each other or place computers so near each other that they

are subject to each other’s re-circulated 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.

■ The computer is designed to operate continuously (24x7), provided that the operating

guidelines listed above are met.

■ Install or enable power management functions of the operating system or other software,

including sleep states.

5.4 Routine Care

5.4.1 General Cleaning Safety Precautions

1. Never use solvents or flammable solutions to clean the computer.

2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth

3. Always unplug the computer when cleaning with liquids or damp cloths.

4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.

5. Disconnect the keyboard before cleaning it.

6. Wear safety glasses equipped with side shields when cleaning the keyboard.
