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.
7
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.
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
English
Finding your comfort zone
English

•
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.

Attaching / Removing the base
Note: Remove the monitor and monitor base from its packaging.
Carefully place the monitor face-down on a stable surface — use a
cloth to avoid scratching the screen.
To install, align the base with the stand and push the base towards the top of
the monitor. Tighten the screw clockwise.
Reverse the steps to remove.
Adjusting the screen position
15°
5°
In order to optimize the best viewing position,
you can adjust the tilt of the monitor by using
both of your hands to hold the edges of the
monitor as shown in the figure.
The monitor can be adjusted to 15 degrees up or
5 degrees down as indicated by the arrow.
Connecting the power cord
•
Check first to make sure that the power cord you use is the correct type
required for your area.
•
This monitor has a universal power supply that allows operation in either
100/120V AC or 220/240 V AC voltage area. No user-adjustment is required.
•
Plug one end of the power cord to the AC inlet and plug the other end to a
proper AC outlet.
11
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 (outside of the U.S.): 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.
Safety precaution
•
Avoid placing the monitor, or any other heavy object, on the power cord
to avoid damage to the cable.
•
Do not expose the monitor to rain, excessive moisture, or dust.
•
Do not cover the ventilation slots or openings of the monitor. Always put
the monitor in a place where there is adequate ventilation.
•
Avoid placing the monitor against a bright background or where sunlight
or other light sources may reflect on the face of the monitor. Place the
monitor just below eye level.
•
Handle with care when transporting the monitor.
•
Refrain from giving shock or scratch to the screen, as screen is fragile.
Cleaning your monitor
•
Always unplug the monitor before cleaning.
•
Use a soft cloth to wipe the screen and cabinet front and sides.
Power saving
The monitor will be switched into power saving mode by the control signal
from the display controller, as indicated by the amber-color power LED.

Display Data Channel (DDC)
To make your installation easier, the monitor is able to Plug and Play with your
system if your system supports DDC protocol — 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 DDC2B standard.
