of high-trafﬁc areas. If you must operate your computer in or near a high-trafﬁc

area, inspect and, if necessary, clean your computer more frequently.

For your safety and to maintain optimum computer performance, always follow

these basic precautions with your desktop computer:

• Keep the cover closed whenever the computer is plugged in.

• Regularly inspect the outside of the computer for dust accumulation.

• Remove dust from vents and any perforations in the bezel. More frequent

cleanings might be required for computers in dusty or high-trafﬁc areas.

• Do not restrict or block any ventilation openings.

• Do not store or operate your computer inside furniture, as this might increase

the risk of overheating.

• Airﬂow temperatures into the computer should not exceed 35° C (95° F).

• Do not use non-desktop air ﬁltration devices.

Operating environment

The optimal environment in which to use your computer is 10°C-35°C (50°F-95°F) with

humidity ranging between 35% and 80%. If your computer is stored or transported

in temperatures less than 10°C (50°F), allow the cold computer to rise slowly to an

optimal operating temperature of 10°C-35°C (50°F-95°F) before use. This process

could take two hours in extreme conditions. Failure to allow your computer to rise

to an optimal operating temperature before use could result in irreparable damage

to your computer.

If possible, place your computer in a well-ventilated and dry area without direct

exposure to sunshine.

Keep electrical appliances such as an electric fan, radio, high-powered speakers,

air conditioner, and microwave oven away from your computer because the strong

magnetic ﬁelds generated by these appliances can damage the monitor and data

on the hard disk drive.

Do not place any beverages on top of or beside the computer or other attached

devices. If liquid is spilled on or in the computer or an attached device, a short

circuit or other damage might occur.

Do not eat or smoke over your keyboard. Particles that fall into your keyboard can

cause damage.
