TCO’95  
Congratulations! You have just purchased a  
TCO95 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.

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 TCO95 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).  
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

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 back-  
light 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 earths atmosphere with  
consequent increased risks of skin cancer (malignant melanoma).  
The relevant TCO95 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.

Congratulations! You have just purchased a TCO99  
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

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 electron-  
ics 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

sumption to a lower level in one or more stages. The length of time to  
reactivate the computer shall be reasonable for the user.

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 TCO99 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 colour-  
generating layers of certain computer displays. Cadmium damages the  
nervous system and is toxic in high doses. The relevant TCO99 require-  
ment 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  
TCO99 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 TCO99 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 capaci-  
tors. Lead damages the nervous system and in higher doses, causes  
lead poisoning. The relevant TCO99 requirement permits the inclusion  
of lead since no replacement has yet been developed.

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 Istands 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.  
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

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.  
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.  
If the monitor has been dropped or the cabinet is damaged.  
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 monitors 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  
DETECTmode. 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 automati-  
cally 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.

* 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.

Technical specifications are subject to change without notice.

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 ghostof an image remains on the screen  
even after the monitor has been turned off. Unlike CRT monitors, LCD  
monitorsimage 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 ghostof 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.)  
USB Hub does not operate  
Check to make sure the USB cord is properly connected. Refer to  
your USB device Users Manual.  
Check the OSM INPUT SELECT and the USB input connector on the  
back of the monitor.  
No Video  
If no video is present on the screen, turn the Power button off and on  
again.
