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 the display to 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 (15.75 inches) and no further away than 70 cm (27.56 inches) from your eyes. The optimal distance is 50 cm (19.69 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 refl ections. Adjust the monitor tilt so that ceiling lights do not refl ect on your screen.

If refl ected light makes it hard for you to see your screen, use an anti-glare fi lter.

• 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 fi xed 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 benefi ts, we recommend the following:

To avoid eye fatigue, adjust the brightness to a moderate setting. Place a sheet of white paper next to the LCD screen for luminance reference.

Do not position the Contrast control to its maximum setting.

Use the preset Size and Position controls with standard signals.

Use the preset Color Setting.

Use non-interlaced signals with a vertical refresh rate of more than 60 Hz.

Do not use primary color blue on a dark background, as it is diffi cult to see and may produce eye fatigue due to insuffi cient contrast.

Cleaning the LCD Panel

When the LCD is dirty, please wipe gently with soft cloth.

Please do not rub the LCD panel with hard or coarse material.

Please do not apply pressure to the LCD surface.

Please do not use OA cleaner as it will cause deterioration or discoloration on the LCD surface.

Cleaning the Cabinet

Unplug the power supply

Gently wipe the cabinet with a soft cloth

To clean the cabinet, dampen the cloth with a neutral detergent and water, wipe the cabinet and follow with a dry 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 time. These types of fl uids and fabrics can cause the paint to deteriorate, crack or peel.
