CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR

CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE

FOLLOWING WHEN YOU POSITION THE MONITOR:

Recommended Use

–continued

• 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 24 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 anti-glare filter.

• Clean your monitor regularly. Use a lint-free, non-abrasive cloth and a

non-alcohol, neutral, non-abrasive cleaning solution or glass cleaner to

minimize dust.

• 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:

• 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 and Sides Left/Right controls

• Use non-interlaced signals with a vertical refresh rate between 75-120Hz

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

and may produce eye fatigue due to insufficient contrast
