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
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 important 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
- Use 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.
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.
Unpacking
Please check that the following items are present when you unpack the box, and
save the packing materials in case you need to ship or transport the monitor
in the future.
SCREEN POSITION ADJUSTMENT
To optimize the best viewing position, you can adjust the tilt of the monitor.
Attaching 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.
Tilt
Please see the illustration below for an example of the tilt range. Only at
the highest point can 20 degrees of recline be offered for the angle of
elevation.
- 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 areas. No user adjustment is required.
- Plug one end of the AC power cord into 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 an 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 driven into “Power Saving” mode by the control signal from
the display controller, as indicated by the amber-color power LED. The power
saving states will be kept until a control signal has been detected or the
keyboard
or mouse is activated
State | LED Light |
---|---|
ON | Blue |
Power Saving Mode | Amber |
Display Data Channel (DDC)
To make installation easier, so long as your system supports the DDC protocol,
the monitor can 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.
