Safety and warranty guide

Inspect your desktop computer for dust accumulation at least once every three

months. Before inspecting your computer, turn off the power and unplug the

computer’s power cord from the electrical outlet; then remove any dust from

vents and perforations in the bezel. If you notice external dust accumulation, then

examine and remove dust from the inside of the computer including heat sink

inlet ﬁns, power supply vents, and fans. Always turn off and unplug the computer

before opening the cover. If possible, avoid operating your computer within 2 feet

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.

• Airowtemperaturesintothecomputershouldnotexceed35°C(95°F).

• Donotusenon-desktopairltration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.
