Tips and information for comfortable use
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.
•Avoid slouching forward and/or leaning backward.
•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.

viii
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.
•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, such as open windows, for extended
periods of time.
Developing good work habits
Develop the following work habits to make your 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.
Warning! 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.

Frequently asked questions
The following questions are possible situations that may arise during
the use of your computer and each is followed by easy answers and
solutions to the situation.
Q: I pressed the power switch but the system did not boot up.
A: Check the LED located above the power switch.
If the LED is not lit, no power is being applied to the system. Do any of
the following:
• Check if the voltage selector switch located on the rear panel of
the computer is set to the correct voltage.
• Check if you plugged the power cable properly into an electrical
outlet.
• If you are using a power strip or AVR, make sure that it is plugged
in and turned on.
If the LED is lit, check the following:
• Is a non-bootable (non-system) diskette in the floppy drive? If yes,
remove or replace it with a system diskette and press Ctrl + Alt +
Del to restart your computer.
•The operating system files may be damaged or missing. Insert the
start-up disk you created during Windows setup into the floppy
drive and press Ctrl + Alt + Del to restart your computer. This will
automatically diagnose your system and make necessary fixes.
However, if the diagnostic utility still reports a problem, then you
may have to perform the recovery process to restore your system
to its original default factory settings.
Note: For more information about recovering your system,
refers to the RCD instruction sheet.
Q: Nothing appears on the screen.
A: Your computer's power management function automatically blanks
the screen to save power. Just press any key to turn the display back
on.
If pressing a key does not work, you can restart your computer. If
restarting your computer does not work, contact your dealer or the
technical support center for assistance.
