Introduction
Thank you for purchasing a high resolution monitor. It will give you
high rwolution performance and convenient reliable operation in a
variety of video operating mods.
. The monitor is a 21 inches (20 inches viewable ) intelligent.
microprocessor based monitor compatible with most analog RGB (Red,
Green, Blue) display standards, including IBM P0. PS/Z'. Apple‘,
Macintosh‘, Centris‘, Ouadra', and Macintosh II family.
. USB (Universal Serial Busl ports at the back of the monitor are prepared
for the USB cable and hub. You can easily and flexibly connect USB-
designed devices-such as a mouse, keyboard or printer- to the monitor
for true Plug and Play function.
. The monitor provides crisp text and vivid color graphics with VGA,
SVGA, XGA, and VESA Ergonomic modes (non—interlaced), and most
Macintosh compatible color video cards when used with the appropriate
adaptor. The monitor's wide compatibility makes it possible to upgrade
video cards or software without purchasing a new monitor.
. Digitally controlled autoscanning is done with the microprocessor for
horizontal scan frequencies between 30 and 1 15kHz, and vertical scan
frequencies between 50200HZ. The microprocessorbased intelligence
allows the monitor to operate in each frequency mode with the
precision of a fixed frequency monitor.
. We managed to adapt the advanced design and technology to the
monitor. Soft touch buttons on the front panel are simple and allow you
to conveniently adjust a variety of image controls. The absolutely flat
screen and special screen treatment virtually eliminate distracting glares,
. This monitor is capable of producing a maximum horizontal resolution of
1600 dots and a maximum vertical resolution of 1200 lines. It is well
suited for CAD work and sophisticated windowing environments.
. For low cost of monitor operation, this monitor is certified as meeting
the EPA Energy Star requirements, and utilizes the VESA Display Power
Management Signalling lDPMSl protocol for power saving during now
use periods.

Energy Saving Design
This monitor complies with the EPA's Energy Star program, which is a
program designed to have manufacturers of computer equipment build
circuitry into their products to reduce power consumption during time of
nonuse.
This monitor also goes into its energy saving mode if you exceed the
monitor's operating limits, such as the maximum resolution of 1600x1200
or the frequency refresh rates of30-115kHz horizontal or 50-200Hz
vertical, When this monitor is used with a Green or EPA Energy Star PC,
or a PC with a screen blanking software following the VESA Display
Power Management Signalling lDPMSl protocol, this monitor can
conserve significant energy by reducing power consumption during
periods of nonuse. When the PC goes into the energy saving mode, the
monitor will go into a suspended operation state, indicated by the Power
LED light changing from a green color to an amber color. After an
extended period in the suspended mode, the monitor will then enter a
semi—OFF mode to conserve more energy. In the semiOFF mode or
DPMS OFF mode as we call it in our specifications, the Power LED will
still show an amber color. When you awaken your PC by hitting a key or
moving the mouse, the monitor will also awaken to its normal operating
mode, indimted by the green Power LED light. By following these
conventions, the power consumption can be reduced to the following
levels:

What does labelllng
Involve?
Environmental Labelling of Personal Computers
You have just purchased a TCO'99 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,
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 ooncemed, is that environmentally hamtful
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 lextemall environments. Since all methods ol
electricity generation have a negative effect on the environment (eg.
acidic and climateinfluencing 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.
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 cl Professional Employees), Svenska
Naturskyddsforeningen (The Swedish Society for Nature Conservation)
and Statens Energimyndighet (The Swedish National Energy
Administration).
Appendix
Environmental Labelling of Personal Computers
Approval remiren'ients cover a wide range of issues: environment,
ergonomics, usability, emission of electric and magnetic fields, energy
consumption and electrical and fire safety.
The environmental demands in‘pose 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 poliw 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,
