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 to the further
development of environmentally-adapted electronic 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 electronic equipment are concerned is that environmentally
harmful substances are used both in the products and during their manufacture. Since it
has not been possible so far for the majority of electronic 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 both the working and natural environment viewpoints. Since all
types 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. Electronic equipment in offices consumes an enormous amount of energy, since it
is often routinely left running continuously.

What does labelling involve?

This product meets the requirements for the TCO'95 scheme, which provides for
international 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 among other things restrictions on the presence
and use of heavy metals, brominated and chlorinated flame retardants, CFCs (freons),
and chlorinated solvents. 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, along with physical and visual ergonomics and
good usability.

Environmental Requirements

Brominated flame retardants are present in printed circuit boards, cabling, casings and
housings, and are added to delay the spread of fire. Up to 30 % of the plastic in a computer
casing can consist of flame-retardant substances. These are related to another group of
environmental toxins, PCB, and are suspected of giving rise to similar harm, including repro­ductive damage in fish-eating birds and mammals. Flame retardants have been found in
human blood and researchers fear that they can disturb foetus development.
Bio-accumulative* TCO'95 demands require that plastic components weighing more than 25
grammes must not contain frame retardants with organically bound chlorine or bromine.

Lead

can be found in picture tubes, display screens, solder and capacitors. Lead damages the
nervous system and in higher doses, causes lead poisoning.
The relevant bio-accumulative* TCO'95 requirement permits the inclusion of lead, as no
replacement has yet been developed.

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 bio-accumulative* TCO'95 requirement states that batteries may not contain
more than 25 ppm (parts per million) of cadmium. The colour-generating layers of display
screens must not contain any cadmium.

Mercury

is sometimes found in batteries, relays and switches. Mercury damages the nervous system
and is toxic in high doses. The relevant bio-accumulative* TCO'95 requirement states that
batteries may no contain more than 25 ppm (part per million) of mercury.

demands require that no mercury is present in any of the electrical or electronic components
concerned with the display unit.

CFCs (freons) are sometimes used for washing printed circuit boards and in the

manufacture of expanded foam for packaging. CFCs break down ozone and thereby
damage the ozone layer in the stratosphere, causing increased reception on Earth of
ultra-violet light with consequent increased risks of skin cancer (malignant melanoma).
The relevant TCO'95 requirement: Neither CFCs nor HCFCs may be used during
manufacture of the product or its packaging.

* Bio-accumulative is defined as substances which accumulate within living organisms.

1.2 Internal Preset Memory Capability

To minimize adjustment needs, the factory has preset popular display standards into the monitor,
as shown in Table 1. If any of these display standards are detected, the picture size and center­ing are automatically adjusted. All of the factory presets may be overwritten by adjusting the user
controls. The monitor is capable of automatically storing up to twelve additional display stan­dards. The new display information must differ from any of the existing display standards by at
least 1kHz for the horizontal scan frequency or 5Hz for the vertical scan frequency or the sync
signal polarities must be different.

1.3 Power Management Function

The monitor has the power management function which reduces the power consumption of the
monitor when not in use. There are two reduced power level modes.

Stand-by mode

When the horizontal sync signal is off, the monitor is switched to a stand-by mode. When the
monitor is in stand-by mode, the screen is off and the power indicator will blink for 0.5 second
intervals.
After the horizontal sync signal is restored, picture will be displayed immediately.

Suspend mode

When the vertical sync signal is off, after about 10 seconds the monitor is switched to a
suspend mode which reduces the monitor power consumption to less than 15W.
When the monitor is in suspend mode, the screen is off and the power indicator will blink for
two second intervals. After the vertical sync signal is restored, picture will be displayed within
a few seconds.

Power-off mode

When the horizontal sync signal and vertical sync signal are off, after about 10 seconds the
monitor is switched to a power-off mode, which reduces the monitor power consumption to
less than the power consumed at suspend mode above.
When the monitor is in power-off mode, the screen is off, and the power indicator will blink for
3 seconds of On-time and 1 second Off-time.
After both the sync signals are restored, picture will be displayed within several seconds.

1.4 DDC

The monitor includes the DDC1 and DDC2B feature. DDC (Display Data Channel) is a communi­cation channel over which the monitor automatically informs the host system about its capabilities
(e.g. each supported resolution with its corresponding timing).
DDC is routed through previously unused pins of the 15-pin VGA connector.
The system will perform "Plug and Play" feature if both, monitor and host, implement the DDC
protocol.

1.5 Location Considerations

When setting up and using the monitor, keep the following in mind:

* For optimum viewing, avoid placing the monitor against a bright background or where sunlight

or other light sources may reflect on the display area of the monitor; place the monitor just
below eye level.

* Place the monitor away from strong magnetic or electromagnetic fields, such as

high capacity transformers, electric motors, large current power lines, steel pillars,

etc.... Magnetism can cause distortion in the picture and/or color purity.

* Avoid covering the slots or openings of the monitor. Allow adequate ventilation

around the monitor so the heat from the monitor can properly dissipate. Avoid putting the
monitor into any enclosure that does not have adequate ventilation.

* Avoid exposing the monitor to rain, excessive moisture, or dust, as this can

cause a fire or shock hazard.

* Avoid placing the monitor, or any other heavy object, on the power cord.

Damage to the power cord can cause a fire or electrical shock.

* When transporting the monitor, handle it with care.

CAUTION

Keep your fingers away from the pivot area of the tilt/swivel base.

1.6 Cleaning Your Monitor

When cleaning the monitor, please follow these guidelines:

* Always unplug the monitor before cleaning.
* Wipe the screen and cabinet front and sides with a soft cloth.
* If the screen requires more than dusting, apply a household window cleaner to a soft cloth to

clean the monitor screen.

CAUTION

Do not use benzene, thinner or any volatile substances to clean the unit as the finish may be
permanently marked. Never leave the monitor in contact with rubber or vinyl for an extended time
period.
