Recommended Use cont.

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 16 inches and
no further away than 28 inches from your eyes. The
optimal distance is 21 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.

• If reflected light makes it hard for you to see your screen, use an anti-glare 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:

•

Adjust the Brightness until the background raster disappears

•

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 with a vertical refresh rate between 60-75Hz

•

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

Features

ambix™ Technology: Dual input technology allowing both analog and digital
inputs off of one connector (DVI-I) as well as additional legacy analog support off
of a traditional 15-pin VGA connector. Provides traditional MultiSync® technol­ogy compatibility for analog as well as TMDS™-based (Transition Minimized
Differential Signaling) digital compatibility for digital inputs. TMDS-based digital
interfaces include DVI-D, DFP and P&D.

DVI-I: The intergrated interface ratified by the Digital Display Working Group
(DDWG) that allows both digital and analog connectors off of one port. The “I”
stands for integration for both digital and analog, The digital portion is TMDS­based.

DVI-D: The digital-only subset of DVI ratified by the Digital Display Working
Group (DDWG) for digital connections between computers and displays. As a
digital-only connector, analog support is not provided off a DVI-D connector. As
a TMDS-based digital only connection, only a simple adapter is necessary for
compatibility between DVI-D and other TMDS-based digital connectors such as
DFP and P&D.

DFP (Digital Flat Panel): An all-digital interface for flat panel monitors which is
signal compatible with DVI. As a TMDS-based digital only connection, only a
simple adapter is necessary for compatibility between DFP and other TMDS­based digital connectors such as DVI and P&D.

P&D (Plug and Display): The VESA standard for digital flat panel monitor
interfaces. It is more robust than DFP since it allows for other options off a signal
connector (options like USB, analog video and IEEE-1394-995). The VESA
committe has recognized that DFP is a subset of P&D. As a TMDS-based connec­tor (for the digital input pins), only a simple adapter is necessary for compatibility
between P&D and other TMDS-based digital connector such as DVI and DFP.

NuCycle™ Plastic: A special silicone compound for PC resin, being extremely
flame retardant, safe and environmentally friendly.

Dual Inputs: Offers dual inputs, allowing you to connect the monitor to two
systems. You can easily switch between computers with a touch of a button on the
front control panel.

USB Hubs: There is a USB Hub, two upstream ports and four downstream ports.
You can use two sets of computers with one monitor.

Reduced Footprint: Provides the ideal solution for environments requiring
superior image quality but with size and weight limitations. The monitor’s small
footprint and low weight allow it to be moved or transported easily from one
location to another.

The signal cable should be completely connected to the display card/computer.

• The display card should be completely seated in its slot.

• Power button and computer Power button should be in the ON position.

• Check to make sure that a supported mode has been selected on the display
card or system being used. (Please consult display card or system manual to
change graphics mode.)

• Check the monitor and your display card with respect to compatibility and
recommended settings.

• Check the signal cable connector for bent or pushed-in pins.

• Check the cables of Video input 1 or Video input 2 to make sure they are
properly connected. Then make sure the input select is set to the proper Video
input.

• Check the DVI Selection in OSM.

Power Button does not respond

• Unplug the power cord of the monitor from the AC outlet to turn off and reset
the monitor, or simultaneously press the RESET and Power buttons.

Image persistence

• Image persistence is when a “ghost” of an image remains on the screen even
after the monitor has been turned off. Unlike CRT monitors, LCD monitors’
image persistence is not permanent. To alleviate image persistence, turn the
monitor off for as long as an image was displayed. If an image was on the
monitor for one hour and a ”ghost” of that image remains, the monitor
should be turned off for one hour to erase the image.

NOTE: As with all personal display devices, NEC Technologies recommends
using a screen saver at regular intervals whenever the screen is idle.

Image is unstable, unfocused or swimming is apparent

• Signal cable should be completely attached to the computer.

• Use the OSM™ Image Adjust controls to focus and adjust display by
increasing or decreasing the fine total. When the display mode is changed,
the OSM Image Adjust settings may need to be re-adjusted.

• Check the monitor and your display card with respect to compatibility and
recommended signal timings.

• If your text is garbled, change the video mode to non-interlace and use
60Hz refresh rate.

LED on monitor is not lit

• Power Switch should be in the ON position and power cord should be
connected.

• Make certain the computer is not in a power-saving mode (touch the
keyboard or mouse).

TCO’99

Congratulations! You have just purchased a TCO’99 approved and
labeled product! Your choice has provided you with a product devel­oped for professional use. Your purchase has also contributed to
reducing the burden on the environment and also to the further
development of environmentally adapted electronics products.

Why do we have environmentally labelled computers?

In many countries, environmental labelling has become an established method for encourag­ing the adaptation of goods and services to the environment. The main problem, as far as
computers and other electronics equipment are concerned, is that environmentally harmful
substances are used both in the products and during the manufacturing. Since it has not been
possible for the majority of electronics equipment to be recycled in a satisfactory way, most
of these potentially damaging substances sooner or later enter Nature.

There are also other characteristics of a computer, such as energy consumption levels, that are
important from the viewpoints of both the work (Internal) and natural (external) environments.
Since all methods of conventional electricity generation have a negative effect on the
environment (acidic and climate-influencing emissions, radioactive waste, etc.), it is vital to
conserve energy. Electronics equipment in offices consume an enormous amount of energy
since they are often left running continuously.

What does labelling involve?

This product meets the requirements for the TCO’99 scheme which provides for international and
environmental labelling of personal computers. The labelling scheme was developed as a joint
effort by the TCO (The Swedish Confederation of Professional Employees), Svenska
Naturskyddsforeningen (The Swedish Society for Nature Conservation) and Statens Energimyndighet
(The Swedish National Energy Administration).

The requirements cover a wide range of issues: environment, ergonomics, usability, emission of
electrical and magnetic fields, energy consumption and electrical and fire safety.

The environmental demands concern restrictions on the presence and use of heavy metals,
brominated and chlorinated flame retardants, CFCs (freons) and chlorinated solvents, among other
things. The product must be prepared for recycling and the manufacturer is obliged to have an
environmental plan which must be adhered to in each country where the company implements its
operational policy. The energy requirements include a demand that the computer and/or display,
after a certain period of inactivity, shall reduce its power consumption to a lower level in one or
more stages. The length of time to reactivate the computer shall be reasonable for the user.

Labelled products must meet strict environmental demands, for example, in respect of the reduction
of electric and magnetic fields, physical and visual ergonomics and good usability.

Environmental Requirements

Flame retardants
Flame retardants are present in printed circuit boards, cables, wires, casings and housings. In turn,
they delay the spread of fire. Up to thirty percent of the plastic in a computer casing can consist of
flame retardant substances. Most flame retardants contain bromine or chloride and these are
related to another group of environmental toxins, PCBs, which are suspected to give rise to severe
health effects, including reproductive damage in fisheating birds and mammals, due to the bio-

TCO’99 cont.

accumulative* processes. Flame retardants have been found in human blood and researchers fear
that disturbances in foetus development may occur.

TCO’99 demand requires that plastic components weighing more than 25 grams must not contain
flame retardants with organically bound chlorine and bromine. Flame retardants are allowed in
the printed circuit boards since no substitutes are available.

Lead**

Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the
nervous system and in higher doses, causes lead poisoning.

TCO’99 requirement permits the inclusion of lead since no replacement has yet been developed.

Cadmium**

Cadmium is present in rechargeable batteries and in the colourgenerating layers of certain
computer displays. Cadmium damages the nervous system and is toxic in high doses.

TCO’99 requirement states that batteries, the colourgenerating layers of display screens and the
electrical or electronics components must not contain any cadmium.

Mercury**

Mercury is sometimes found in batteries, relays and switches, Mercury damages the nervous system
and is toxic in high doses.

TCO’99 requirement states that batteries may not contain any Mercury. It also demands that no
mercury is present in any of the electrical or electronics components associated with the display unit.

CFCs (freons)

CFCs (freons) are sometimes used for washing printed circuit boards. CFCs break down ozone and
thereby damage the ozone layer in the stratosphere, causing increased reception on Earth of
ultraviolet light with consequent increased risks of skin cancer (malignant melanoma).

The relevant TCO’99 requirement; Neither CFCs nor HCFCs may be used during the manufacturing
and assembly of the product or its packaging.

*Bio-accumulative is defined as substances which accumulate within living organisms.
**Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
