Some of the information in this guide may not apply to your computer.
Computer users may complain of eyestrain and headaches after
prolonged use. Users are also at risk of physical injury after long
hours of working in front of a computer. Long work periods, bad
posture, poor work habits, stress, inadequate working conditions,
personal health and other factors greatly increase the risk of physical
injury.
Incorrect computer usage may lead to carpal tunnel syndrome,
tendonitis, tenosynovitis or other musculoskeletal disorders. The
following symptoms may appear in the hands, wrists, arms, shoulders,
neck or back:
• Numbness, or a burning or tingling sensation.
• Aching, soreness or tenderness.
• Pain, swelling or throbbing.
• Stiffness or tightness.
• Coldness or weakness.
If you have these symptoms, or any other recurring or persistent
discomfort and/or pain related to computer use, consult a physician
immediately and inform your company's health and safety
department.
The following section provides tips for more comfortable computer
use.
Finding your comfort zone
Find your comfort zone by adjusting the viewing angle of the monitor,
using a footrest, or raising your sitting height to achieve maximum
comfort. Observe the following tips:
• Refrain from staying too long in one fixed posture.
• Stand up and walk around regularly to remove the strain on your leg
muscles.
• Take short rests to relax your neck and shoulders.
• Avoid tensing your muscles or shrugging your shoulders.
• Install the external display, keyboard and mouse properly and within
comfortable reach.
• If you view your monitor more than your documents, place the
display at the center of your desk to minimize neck strain.
Taking care of your vision
Long viewing hours, wearing incorrect glasses or contact lenses,
glare, excessive room lighting, poorly focused screens, very small
typefaces and low-contrast displays could stress your eyes. The
following sections provide suggestions on how to reduce eyestrain.
Eyes
• Rest your eyes frequently.
• Give your eyes regular breaks by looking away from the monitor and
focusing on a distant point.
• Blink frequently to keep your eyes from drying out.
Display
• Keep your display clean.
• Keep your head at a higher level than the top edge of the display so
your eyes point downward when looking at the middle of the display.
• Adjust the display brightness and/or contrast to a comfortable level
for enhanced text readability and graphics clarity.
• Eliminate glare and reflections by:
• placing your display in such a way that the side faces the window
or any light source,
• minimizing room light by using drapes, shades or blinds,
• using a task light,
• changing the display's viewing angle,
• using a glare-reduction filter,

Warning
Warning
• using a display visor, such as a piece of cardboard extended from
the display's top front edge.
• Avoid adjusting your display to an awkward viewing angle.
• Avoid looking at bright light sources for extended periods of time.
Developing good work habits
The following work habits make computer use more relaxing and
productive:
• Take short breaks regularly and often.
• Perform some stretching exercises.
• Breathe fresh air as often as possible.
• Exercise regularly and maintain a healthy body.
We do not recommend using the computer on a couch or bed. If this is
unavoidable, work for only short periods, take breaks regularly, and do
some stretching exercises.
Protecting your hearing
Permanent hearing loss may occur if earphones or
headphones are used at high volume for prolonged periods of
time.
To protect your hearing, follow these instructions.
• Increase the volume gradually until you can hear clearly and
comfortably.
• Do not increase the volume level after your ears have adjusted.
• Do not listen to music at high volumes for extended periods.
• Do not increase the volume to block out noisy surroundings.
• Decrease the volume if you can't hear people speaking near you.
