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 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. Case of

persistent dirt, wipe with cloth permeated by water, ethanol, isopropyl-

alcohol completely. Avoid using any cleaning solution or glass cleaner (ex

Acid, Alkali and Acetone).

• 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:

•

Adjust the Brightness until the background raster disappears

•

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 moer than 60Hz

•

Do not use primary color blue on a dark background, as it is difficult to see and

may produce eye fatigue to insufficient contrast
