Handling the power cord.
Handle the power cord with care. Damaging the cord could lead to fire or electric shock.
• When connecting the power cord to the monitor’s AC IN terminal, make sure the connector is fully and
firmly inserted.
• Do not connect or disconnect the power cord with wet hands.
• When connecting or disconnecting the power cord, pull the power cord out by holding onto its plug.
• When cleaning the monitor, for safety purposes unplug the power cord from the power outlet
beforehand. Regularly dust off the power cord by using a soft dry cloth.
• Before moving the monitor, make sure the monitor power is off, then unplug the power cord from the
power outlet and check that all cables connecting the monitor to other devices are disconnected.
• When you are not planning to use the monitor for an extended period of time, always unplug the
power cord from the power outlet.
To ensure the monitor’s reliability, please clean the ventilation holes at the rear side of the cabinet at least
once a year to remove dirt and dust.
Handle with care during installation and adjustment to prevent personal injury and damage to the monitor.
English
The monitor must be mounted to a flexible arm or stand that supports the weight of the monitor to prevent
damage and personal injury that could result from the monitor tipping over or falling.
• Please tighten all screws when installing the monitor to a flexible arm or stand. A loose screw may
cause the monitor to fall, causing damage to the monitor or personal injury.
Do not connect headphones to the monitor while you are wearing them. Depending on the volume level, it
may damage your ears and cause loss of hearing.
CAUTION
Please install the monitor in accordance with the following information.
Improper installation of the monitor may result in damage to the monitor, an electric shock or fire.
• Allow adequate ventilation around the monitor, so that heat can properly dissipate.
• Do not cover the vent on the monitor.
Clean the monitor’s LCD screen surface with a lint-free, non-abrasive cloth.
Avoid using any cleaning solutions! DO NOT clean with benzene thinner, alkaline detergent, alcoholic
system detergent, glass cleaner, wax, polish cleaner, soap powder, or insecticide. Rubber or vinyl should
not be in contact with the cabinet for an extended period of time. These types of fluids and materials can
cause the paint to deteriorate, crack or peel.
English−5
Image Persistence
Image persistence occurs 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 a still image 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 DISPLAY SOLUTIONS recommends using a moving screen saver at regular
intervals whenever the screen is idle, or turn off the monitor when not in use.
English−6
Ergonomics
CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR CAN
REDUCE EYE, SHOULDER, AND NECK FATIGUE. CHECK THE
FOLLOWING WHEN YOU POSITION THE MONITOR:
To realize the maximum ergonomics benefits, we recommend the following:
• For optimum performance of the monitor, allow 20 minutes for warming up. Avoid
reproduction of still patterns on the monitor for long periods of time to avoid image
persistence (after image effects).
• 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 (15.75 inches) and no further away than
70 cm (27.56 inches) from your eyes. The optimal distance is 50 cm (19.69 inches).
• Rest your eyes periodically for 5 to 10 minutes for every 1 hour by focusing on an object
at least 20 feet away.
• 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.
• 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.
• Blink often. Eye exercise helps to reduce eye strain. Please contact your ophthalmologist. Get regular eye checkups.
• To avoid eye fatigue, adjust the brightness to a moderate setting. Place a sheet of white paper next to the LCD screen for
luminance reference.
• 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.
• 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.
• Suitable for entertainment purposes at controlled luminous environments, to avoid disturbing reflections from the screen.

• Environmental Impact (AS221F/AS241F)
Annual typical maximum operating carbon footprint of this monitor (world-wide average) is approximately 23.6 kg (AS221F)/
25.5 kg (AS241F) (calculated by: rated wattage x 8 hours per day x 5 days a week x 45 weeks per year x Power-to-Carbon
conversion factor - conversion factor is based on OECD publication of global CO2 emissions 2008 Edition).
This monitor has a manufacturing carbon footprint of approximately 28.6 kg (AS221F)/30.8 kg (AS241F).
Note: The manufacturing and operating carbon footprints are calculated by a unique algorithm developed exclusively by NEC
for its monitors and are accurate at the time of printing. NEC reserves the right to publish updated carbon footprint values.
• Low Blue Light
Low Blue Light function substantially reduces blue light and helps to alleviate eye strain (see page 27).
• Flicker Free
Special backlight system reduces flicker for less eye strain.
