Recommended use
Caution
•Allow adequate ventilation around the monitor so that heat can properly dissipate. Do not
block ventilated openings or place the monitor near a radiator or other heat sources. Do not
put anything on top of monitor.
•The power cable connector is the primary means of detaching the system from the power
supply. The monitor should be installed close to a power outlet, which is easily accessible.
•Handle with care when transporting. Save packaging for transporting.
•Image persistence is when a residual or “ghost” image of a previous image remains visible on
the screen. LCD monitors’ image persistence is not permanent, but constant images being
displayed for a long period of time should be avoided. To alleviate image persistence, turn off
the monitor for as long as the previous image was displayed. For example, if an image was on
the monitor for one hour and a residual image remains, the monitor should be turned off for
one hour to erase the image.
Corrective 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 30 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 40 cm and no further away than 70 cm from your eyes.
The optimal distance is 50 cm.
•Rest your eyes periodically by focusing on an object at least 50 cm away.
•If reflected light makes it hard for you to see your screen, use an anti-glare filter.
•Adjust the monitor’s brightness and contrast controls to enhance readability.
•Use a document holder placed close to the screen.
•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 backlight to best state.
•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.
•Do not use primary color blue on a dark background, as it is difficult to see and may produce
eye fatigue to insufficient contrast.
