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 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.
UNPACKING
Please check the following items are present when you unpack the box, and save the packing materials in case you will need to ship or transport the monitor in future.

SCREEN POSITION ADJUSTMENT
In order to optimize the best viewing position, you can adjust the tilt of the monitor.
- Tilt
Please see the illustration below for an example of the tilt range.
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 into an AC outlet.
- For unit using at 120 V AC: Use a UL Listed Cord Set, Type SVT wire and plug rated 10 A/125 V.
- For unit using at 220/240 V AC (outside of 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.
- Please confirm the distribution system in building installation shall provide the circuit breaker rated 120/240 V, 20 A (maximum).
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 sun-light 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.
- In order to prevent damage to the monitor, do not lift the monitor by its base.
CLEANING YOUR MONITOR
Please carefully follow the below guidelines when cleaning the monitor.
