General conditions
In general, if you are comfortable, so is your computer, but read the
following to make sure your work site provides a proper environment.
■ Make sure there is adequate space around the computer for proper
ventilation.
■ Make sure the AC power cord connects to an outlet that is close to the
computer and easily accessible.
■ The temperature should be 5 to 35 degrees Centigrade (41 to
95 degrees Fahrenheit) and the relative humidity should be 20 to
80 percent.
■ Avoid areas where rapid or extreme changes in temperature or humidity
may occur.
■ Keep the computer free of dust, moisture, and exposure to direct
sunlight.
■ Keep the computer away from heat sources, such as electric heaters.
■ Do not use the computer near liquids or corrosive chemicals.
■ Do not place the computer near objects that create strong magnetic
fields (e.g., stereo speakers).
■ Do not operate the computer in close proximity to a mobile phone.
■ Leave ample ventilation room for the fan. Do not block the vents.
Placement of computer
Position the computer and peripheral devices to provide comfort and safety.
■ Set the computer on a flat surface at a comfortable height and distance.
The display should be no higher than eye level to avoid eye strain.
■ Place the computer so that it is directly in front of you when you work
and make sure you have adequate space to easily operate other
devices.
■ Allow adequate space behind the computer to let you freely adjust the
display. The display should be angled to reduce glare and maximize
visibility.
■ If you use a paper holder, set it at about the same height and distance
as the computer.
