Ergonomics, English-8 | NEC LCD71VM, LCD51VM guide

• 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.

CAUTION	• 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: Image persistence is when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, 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.

NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display-Europe recommends using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.

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 40 cm and no further away than 70 cm from your eyes. The optimal distance is 58 cm.

•Rest your eyes periodically by focusing on an object at least 6 m 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. 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 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:

•Use the preset Size and Position controls with standard signals.

•Use the preset Colour Setting.

•Use non-interlaced signals with a vertical refresh rate between 60-75 Hz.

•Do not use primary colour blue on a dark background, as it is difficult to see and may produce eye fatigue to insufficient contrast.
