WARNING: To reduce the risk of electric shock or damage to your
equipment: Do not disable the power cord grounding plug. The
grounding plug is an important safety feature.
Plug the power cord into a grounded (earthed) electrical outlet that is
easily accessible at all times.
Disconnect power from the monitor by unplugging the power cord
from the electrical outlet.
Do not place anything on power cords or cables. Arrange them so
that no one may accidentally step on or trip over them. Do not pull on
a cord or cable. When unplugging from the electrical outlet, grasp
the cord by the plug.
CAUTION: Burn-in image damage may occur on monitors that
display the same static image on screen for a prolonged period of
time. To avoid burn-in image damage on your monitor screen, you
should always activate a screen saver application or turn off the
monitor when it is not in use for a prolonged period of time.
Selecting the Signal Connectors and Cables
There are two signal input connectors: one VGA connector and
one DVI-I connector. The monitor will automatically determine
which inputs have valid video signals. The inputs can be selected
via the On-Screen Display (OSD) feature or by pressing the
Signal Input Selection control on the monitor front bezel.
The video mode supported by the DVI-I connector is
determined by the video cable used. For digital operation, use
the DVI-D to DVI-D signal cable provided. For analog operation,
a DVI-I to VGA signal cable must be attached to the DVI-I input
(not provided with the monitor).

Energy Saver Feature
When the monitor is in its normal operating mode, the monitor
uses less than 60 watts of power and the Power light is green.
The monitor also supports a reduced power state. The reduced
power state will be entered into if the monitor detects the absence
of either the horizontal sync signal and/or the vertical sync signal.
Upon detecting the absence of these signals, the monitor screen is
blanked, the backlight is turned off, and the Power light is turned
amber. When the monitor is in the reduced power state, the
monitor will utilize less than 5 watts of power. There is a brief
warm up period before the monitor will return to its normal
operating mode.

saver features (sometimes called power management features).

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

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

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.

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 bioaccumulative*
processes. Flame retardants have been found in human blood and
researchers fear that disturbances in foetus development may
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
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 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 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. There is however one exception. Mercury is, for the
time being, permitted in the back light system of flat panel
monitors as there today is no commercially available alternative.
TCO aims on removing this exception when a mercury free
alternative is available.
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 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

cross-sectional area of the wire must be a minimum of 0.75 mm²
or 18AWG, and the length of the cord must be between 6 feet
(1.8 m) and 12 feet (3.6 m). If you have questions about the type
of power cord to use, contact your Compaq authorized service
A power cord should be routed so that it is not likely to be walked
on or pinched by items placed upon it or against it. Particular
attention should be paid to the plug, electrical outlet, and the
point where the cord exits from the product.
