English
• 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 30 cm and no further away than
70 cm from your eyes. The optimal distance is 45 cm.
• Rest your eyes periodically by focusing on an object at least 6 m
away. Blink often.
• Position the monitor at a 90° Xangle 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 controls to its maximum setting.
• Use the preset size and position controls with standard signals.
• Use the preset colour setting and sides Left/Right controls.
• Use non-interlaced signals with a vertical refresh rate between
75-120Hz.
• Do not use primary colour blue on a dark background, as it is difficult
to see and may produce eye fatigue due to insufficient contrast.
