TCO’95
Congratulations! You have just purchased a
TCO’95 approved and labelled 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.
English-4
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 is as yet not possible to satisfactorily recycle the majority of
electronics equipment, most of these potentially damaging substances
will eventually enter the environment.
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’95 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),
Naturskyddsforeningen (The Swedish Society for Nature Conservation)
and NUTEK (The National Board for Industrial and Technical
Development in Sweden).
English
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 directive that the computer and/or
display, after a certain period of inactivity, shall reduce its power
consumption to a lower level. The length of time to reactivate the
computer shall be reasonable for the user.
English-5
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.
On the back page of this folder, you will find a brief summary of the
environmental requirements met by this product. The complete
environmental criteria document may be ordered from:

TCO’95 is a co-operative project between TCO (The Swedish
Confederation of Professional Employees), Naturskyddsforeningen
(The Swedish Society for Nature Conservation) and NUTEK (The
National Board for Industrial and Technical Development in Sweden).
Environmental Requirements
Brominated flame retardants
Brominated 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. These are related to another group of
environmental toxins, PCBs, which are suspected to give rise to similar
harm, including reproductive damage in fisheating birds and mammals,
due to the bio-accumulative* processes. Flame retardants have been
found in human blood and researchers fear that disturbances in foetus
development may occur.
TCO’95 directive requires that plastic components weighing more than
25 grams must not contain organically bound chlorine and bromine.
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.
English-6
TCO’95 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’95 requirement states that batteries may not contain more than
25 ppm (parts per million) of cadmium. The colourgenerating layers of
display screens must not contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays and switches and backlight system. Mercury damages the nervous system and is toxic in high
doses.
TCO’95 requirement states that batteries must not contain more than
25 ppm (parts per million) of mercury. It also demands that no mercury
is present in any of the electrical or electronics components concerned
with the display unit except the back-light system.
CFCs (freons)
CFCs (freons) are sometimes used for washing printed circuit boards
and in the manufacturing of expanded foam for packaging. CFCs break
down ozone and thereby damagethe ozone layer in the stratosphere,
causing increased ultraviolet light to enter the earth‘s atmosphere with
consequent increased risks of skin cancer (malignant melanoma).
English
The relevant TCO’95 requirement: Neither CFCs nor HCFCs may be
used during the manufacturing 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.

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 their manufacture.
Since it is not so far possible to satisfactorily recycle the majority of
electronics equipment, 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
electricity generation have a negative effect on the environment (e.g.
acidic and climate-influencing emissions, radioactive waste), it is vital to
save energy. Electronics equipment in offices is often left running
continuously and thereby consumes a lot of energy.
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).
Approval requirements cover a wide range of issues: environment,
ergonomics, usability, emission of electric and magnetic fields, energy
consumption and electrical and fire safety.
English-8
The environmental demands impose 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 policy 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

Environmental requirements
Flame retardants
Flame retardants are present in printed circuit boards, cables, wires,
casings and housings. Their purpose is to prevent, or at least to delay
the spread of fire. Up to 30% of the plastic in a computer casing can
consist of flame retardant substances. Most flame retardants contain
bromine or chloride, and those flame retardants are chemically related
to another group of environmental toxins, PCBs. Both the flame
retardants containing bromine or chloride and the PCBs are suspected
of giving rise to severe health effects, including reproductive damage in
fish-eating birds and mammals, due to the bio-accumulative* processes.
Flame retardants have been found in human blood and researchers fear
that disturbances in foetus development may occur.
English-9
The relevant TCO’99 demand requires that plastic components weighing
more than 25 grams must not contain flame retardants with organically
bound bromine or chlorine. Flame retardants are allowed in the printed
circuit boards since no substitutes are available.
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. The relevant TCO’99 requirement states that batteries, the colour-generating 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. It
damages the nervous system and is toxic in high doses. The relevant
TCO’99 requirement states that batteries may not contain any mercury.
It also demands that mercury is not present in any of the electrical or
electronics components associated with the labelled unit.
CFCs (freons)
The relevant TCO’99 requirement states that neither CFCs nor HCFCs
may be used during the manufacture and assembly of the product.
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 e.g. increased risks of skin cancer (malignant melanoma) as a
consequence.
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. The relevant TCO’99 requirement permits the inclusion
of lead since no replacement has yet been developed.
* Bio-accumulative is defined as substances which accumulate within living organisms

Introduction to the NEC MultiSync LCD1525X
Congratulations on your purchase of the NEC MultiSync LCD1525X true
colour monitor!
ambix Technology: Dual input technology allowing both analog and
digital inputs through one connector (DVI-I) as well as additional legacy
analog support through a traditional 15-pin VGA connector. Provides
traditional MultiSync technology compatibility for analog as well as
TMDS (Transition Minimized Differential Signal) based digital
compatibility for digital inputs. TMDS-based digital interfaces include
DVI-D, DFP and P&D.
DVI-I: The integrated interface ratified by the Digital Display Working
Group (DDWG) that allows both digital and analog connectors through
one port. The ”I” stands for integration for both digital and analog. The
digital portion is TMDS based.
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 for
through 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.
English
DFP: Digital Flat Panel - An all digital interface for flat panel monitors
signal compatible with DVI. As TMDS based digital only connection, only
a simple adapter is necessary for compatibility between DFP and other
TMDS based 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
through a single connector (options like USB, analog video and
IEEE-1394-995). The VESA committee 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 connectors such as DVI and DFP.
English-11

top of monitor.
• Do not spill any liquids into the cabinet or use your monitor near
water.
• 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.
• Do not place any heavy objects 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.
• 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 that is easily accessible.
• When operating the MultiSync LCD monitor with its AC100-240V
power supply, use a power supply cord that matches the power
supply voltage of the AC power outlet being used. The power supply
cord you use must have been approved by and comply with the safety
standards of your country.
• Handle with care when transporting. Save packaging for trans-
porting.
• The inside of the fluorescent tube located within the LCD monitor
contains mercury. Please follow the bylaws or rules of your local
municipality to dispose of this tube properly.
• Do not bend power cord.
• Do not use monitor in high temperatured, humid, dusty, or oily areas.
• Do not cover vent on monitor.
English-14
• If monitor is broken, do not come in contact with the liquid crystal.
• If glass is broken. Handle with care.
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.

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 53 cm for the
MultiSync LCD1525X monitor.
• 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 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.

VIDEO DETECT
Selects the method of video detection when two
computers are connected.
NONE
The Monitor will never switch ports automatically, only
by user control.
FIRST DETECT
The video input has to be switched to “FIRST DETECT”
mode. When current video input signal is not present,
then the monitor searches for a video signal from the
other video input port. If the video signal is present in
the other port, then the monitor switches the video
source input port to the new found video source
automatically. The monitor will not look for other video
signals while the current video source is present.
LAST DETECT
The video input has to be switched to the “LAST
DETECT” mode. When the monitor is displaying a signal
from the current source and a new secondary source is
supplied to the monitor, then the monitor will automatically switch to the new video source. When current
video input signal is not present, then the monitor
searches for a video signal from the other video input
port. If the video signal is present in the other port, then
the monitor switches the video source input port to the
new found video source automatically.

Environmental Considerations
* Interpolated Resolutions: When resolutions are shown that are lower than the pixel count of the LCD
module, text may appear different. This is normal and necessary for all current flat panel technologies
when displaying non-native resolutions full screen. In flat panel technolo-gies, each dot on the screen is
actually one pixel, so to expand resolutions to full screen, an interpolation of the resolution must be done.
** Active display area is dependent upon the signal timing.

Troubleshooting/Support
No picture
• 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 switch 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 recommends
using a screen saver at regular intervals whenever the
screen is idle.
English-28
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 Control.
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 60 Hz refresh rate.
LED on monitor is not lit (no green or amber colour
can be seen)
• 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).
Display image is not sized properly
• Use the OSM Image Adjust controls to increase or decrease the
H. Size.
• 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.)
English
USB Hub does not operate
• Check to make sure the USB cord is properly connected. Refer to
your USB device User’s Manual.
• Check the OSM INPUT SELECT and the USB input connector on the
back of the monitor.
