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
viii
English
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.

English
Screen position adjustment
To optimize the viewing position, you can adjust the
monitor tilt, using both of your hands to hold the edges
of the monitor. The monitor can be adjusted to 15
degrees up or 5 degrees down.
Connecting the adapter and AC Power cord
• Check first to make sure that the power cord you use is the correct type required for
your area.
• The monitor has a universal power supply that allows operation in either 100/120 V
AC or 220/240 V AC voltage area. No user-adjustment is required.
• Plug one end of the AC power cord to the Adapter, and plug the other end into an
AC outlet.
• For units using 120 V AC:
Use a UL-listed cord set, type SVT wire and plug rated 10 A/125 V.
• For units using 220/240 V AC:
Use a cord set consisting of H05VV-F cord and plug rated 10 A/250 V. The cord set
should have the appropriate safety approvals for the country in which the equipment
will be installed.
Power saving
The monitor will be switched to “power saving” mode by the control signal from the
display controller, as indicated by the blinking blue light.
Mode LED light

Standby/Power saving Blinking Blue
The power saving mode will be kept until a
control signal has been detected or the keyboard
or mouse is activated. The recovery time from
“power saving” mode back to “on” is around 3
seconds.

English
Display Data Channel (DDC)
To make installation easier, so long as your system supports the DDC protocol, the
monitor is able to plug-and-play. The DDC is a communication protocol through which
the monitor automatically informs the host system about its capabilities; for example,
supported resolutions and corresponding timing. The monitor supports the DDC2B
standard.
