For optimum performance, allow 20 minutes for warm-up.
Adjust the monitor height so that the top of the screen is at or slightly below eye level.
Your eyes should look slightly downward when viewing the middle of the screen.
Position your monitor no closer than 40 cm and no further away than 70 cm from your
eyes. The optimal distance is 50 cm.
Rest your eyes periodically by focusing on an object at least 6 m away. Blink often.
Position the monitor at a 90° angle to windows and other light sources to minimize glare
and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen.
If reflected light makes it hard for you to see your screen, use an antiglare filter.
Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any
cleaning solution or glass cleaner!
Adjust the monitor's brightness and contrast controls to enhance readability.
Use a document holder placed close to the screen.
Position whatever you are looking at most of the time (the screen or reference material) directly in front of you to minimize
turning your head while you are typing.
Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after-image effects).
Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefits, we recommend the following:
Use the preset size and position controls with standard signals.
Use the preset color setting.
Use non-interlaced signals with a vertical refresh rate between 60-75 Hz.
Do not use primary color blue on a dark background, as it is difficult to see and may produce eye fatigue to insufficient
contrast.
Cleaning the LCD Panel
When the liquid crystal panel becomes dusty or dirty, wipe gently with a soft cloth.
Do not rub the LCD panel with coarse or hard material.
Do not apply pressure to the LCD surface.
Do not use OA cleaner as it will cause deterioration or discoloration to the LCD surface.
Cleaning the Cabinet
Unplug the power supply.
Dampen a soft cloth with water and a neutral detergent. Gently wipe the cabinet then dry gently with a soft cloth.
NOTE:
Many plastics are used on the surface of the cabinet. DO NOT clean with benzene, thinner, alkaline detergent,
alcoholic system detergent, glass cleaner, wax, polish cleaner, soap powder or insecticide. Do not touch rubber or
vinyl to the cabinet for a long period of time. These types of fluids and fabrics can cause the paint to deteriorate,
crack or peel.
