SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem.

NOTES

Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the Power Switch and then turn it on again to make sure the flicker disappears.

You may find slightly uneven brightness on the screen depending on the desktop pattern you use.

The LCD screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less such as a missing pixel or a pixel lit all of the time.

Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switching the image, when the same image is displayed for hours. In this case, the screen is recovered slowly by changing the image or turning off the Power Switch for hours.

3D Experience:

3D visual effects require 3D compatible software, nVidia® 3D Visionglasses and a compatible 3D graphics card.

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

EN-3

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 comfort able 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-contrastdisplays 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-reductionfilter

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 product on a couch or bed. If this is unavoidable, work for only short periods, take breaks regularly, and do some stretching exercises.

Plug one end of the power cord to the AC Inlet, plug another end to a proper 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-Fcord 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.
