Looking at features
Your NEC C Series monitor includes a host of features that enhance
performance, ensure your comfort, save power, and let you maximize
your multimedia applications.
Just plug your monitor into a Plug and Play compatible system and
it’s automatically ready to provide optimal performance.
The unlimited color palette and non-glare screen provide a crisp,
detailed image.
Looking at features 9
Your color monitor has the following features:
Plug and Play capability
contemporary ergonomic design
optimized power management system
reduced magnetic field technology
multiple frequency technology
color management with the On-Screen Display (OSD).
Plug and Play
Plug and Play is the Microsoft solution with Windows 95 that
provides automatic peripheral connections without confusing and
time-consuming setup. When used with a Plug and Play compatible
system and display board, the NEC C Series monitor automatically
tells the system its identification and capabilities. The system then
selects its highest resolution and refresh rate to take advantage of the
capabilities of your monitor.
Ergonomic design
The NEC C Series monitor has been designed to enhance human
ergonomics (human and earth conditions), which improve the
working environment, protect the health of the user, and save money.
The color monitor has a tilt/swivel stand so you can adjust it fully for
maximum comfort. It has a high-resolution, flicker-free screen that
can be adjusted using an easy-to-use screen display.
The ergonomic principles used in the monitor design parallel the strict
European standards of power management and reduced emissions and
the requirements in the TCO (Swedish Confederation of Professional
Employees) Agreement on Environmental Labeling 1992.
10 Looking at features
Optimized power management
The NEC C Series monitor uses an optimized power management
system. This is an innovative power-saving feature that complies with
both the EPA’s Energy Star requirements and Europe’s
TCONUTEK’s power management requirements. Energy Star
products use less than 30 watts when in the main power-saving mode.
The NUTEK specification 803299 requires automatic power down to
less than 30 watts in the suspend mode and less than 8 watts in the off
mode.
When in the maximum power-down mode, the monitor consumes
approximately 10% of the total power drawn under normal operation.
This innovation adds up to 90% energy savings, longer monitor life,
environmental protection, reduced emissions, and reduced air
conditioning costs of the work environment.
Reduced emissions
The NEC C Series monitor incorporates reduced magnetic field
technology to reduce magnetic and alternating electric field emissions
and static electricity.
NEC monitors follow the strictest magnetic field, alternating electric
field, and electrostatic recommendations of the Swedish Board for
Technical accreditation.
SWEDAC (previously known as MPR, National Board for
Measurement and Testing) specifies maximum recommended values
of electric and magnetic fields. The NEC C Series monitor conforms
to SWEDAC’s MPR 1990:8 (MPR II) methods, which is one of the
most restrictive guidelines in the world.
Looking at features 11
Multiple frequency technology
Multiple frequency technology automatically adjusts the monitor to
the display card’s scanning frequency, displaying the resolution you
desire.
Increased refresh rates at all resolutions provide a flicker-free image
which is easier on your eyes and extends your viewing time.
Depending on the system used, a wide range of graphics standards is
supported by the monitor:
640 x 480 — 60 to 75 Hz vertical refresh
800 x 600 — 56 to 75 Hz vertical refresh
832 x 624 — 75 Hz vertical refresh
1024 x 768 — 60 to 75 Hz vertical refresh (recommended for
optimal display performance)
1280 x 1024 — 60 Hz (maximum resolution based on
horizontal and vertical frequencies only).
12 Looking at features
Adjusting the monitor
Your NEC C Series monitor features On-Screen Display (OSD)
controls for adjusting monitor settings.
On-Screen Display controls make the monitor easier to use by
providing an on-screen control menu. A touch of the front controls
turns on the OSD, allowing you to move through a menu and adjust
settings.
Adjusting the monitor 13
OSD controls let you adjust the following settings:
horizontal and vertical position
horizontal and vertical size
a convex or concave screen
trapezoid screen shape
color saturation and balance.
You can also use OSD controls to:
return to factory-state settings
degauss (demagnetize) the monitor.
In addition, two manual controls on the front of the monitor allow
you to adjust the brightness and contrast of your monitor screen.
See the following sections for information about using the OSD
controls and the brightness and contrast controls.
Access the On-Screen Display
You can adjust your monitor using a combination of the following
features:
On-Screen Display (OSD) control menu

Working safely 35
Safety precautions
For safety and optimum performance, please note the
following when setting up and using the NEC C Series
monitor.
!
WARNING
DO NOT OPEN THE MONITOR
. There are no user
serviceable parts inside and opening or removing covers may
expose you to dangerous shock hazards or other risks. Refer
all servicing to qualified service personnel.
Do not insert objects of any kind into the cabinet slots, as they
may touch dangerous voltage points, which can be harmful or
fatal or may cause electric shock, fire or equipment failure.
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 the monitor.
To prevent fire or shock hazards, do not expose this unit to
rain or moisture. Do not spill any liquids into the cabinet or
use your monitor near water.
Do not use this unit’s polarized plug with an extension cord
receptacle or other outlets unless the prongs can be fully
inserted.
36 Working safely
Do not place any heavy object on the power cord. Damage to
the cord may cause shock or fire.
Do not place this product on a sloping or unstable cart, stand,
or table, as the monitor may fall, causing serious damage to
the monitor.
Keep the monitor away from high capacity transformers,
electric motors and other devices such as external speakers or
fans, which may create strong magnetic fields.
If possible, position the monitor so that it is facing the east to
minimize the effects of the earth’s magnetic field.
Changing the direction of the monitor while it is powered on
may cause image discoloration. To correct this, turn the
monitor off for 20 minutes before powering it back on.
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.
Immediately unplug your monitor from the wall outlet and refer
servicing to qualified service personnel under the following
conditions:
When the power supply cord or plug is damaged.
If liquid has been spilled, or objects have fallen into the
monitor.
If the monitor has been exposed to rain or water.
If the monitor has been dropped or the cabinet damaged.
If the monitor does not operate normally by following
operating instructions.
Working safely 37
Setting up a healthy work environment
Correct placement and adjustment of the monitor can reduce eye,
shoulder and neck fatigue. Check the following when you position the
monitor:
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 12 inches and no further
away than 28 inches from your eyes. The optimal distance is
18 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.
For more information on setting up a healthy work environment, see
the documentation that comes with your computer.
38 Working safely
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.
