CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR

CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE

FOLLOWING WHEN YOU POSITION THE MONITOR:

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 16 inches and no further away than 28 inches from your eyes. The optimal distance is 20 inches.

Rest your eyes periodically by focusing on an object at least 20 feet 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 refl ected light makes it hard for you to see your screen, use an antiglare filter.

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.

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 60-75Hz

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 sur- face.

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 type of fl uids and fanrics can cause the paint to deteriorate crack or peel.
