RADIO FREQUENCY INTERFERENCE STATEMENT
INFORMATION TO THE USER
NOTE : This equipment has been tested and found to comply with the limits for a
Class B digital device pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet of a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for assistance.
Changes or modification not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
Connecting of peripherals requires the use of grounded, shielded signal cables.
TCO 99
Congratulations ! 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.
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
has not been possible for the majority of electronics 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 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 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), 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 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.
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 99 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 wiring 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, PWBs, which are suspected to give rise to similar harm,
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.
TCO 99 demand 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.
TCO 99 requirement permits the inclusion of lead since no replacement has yet been developed.
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.
TCO 99 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**
Mercury is sometimes found in batteries, relays and switches. Mercury damages the
nervous system and is toxic in high doses.
TCO 99 requirement states that batteries may 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.
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
damage the ozone layer in the stratosphere, causing increased reception on Earth of
ultraviolet light with consequent increased risks of skin cancer (malignant melanoma).
The relevant TCO 99 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.

Overloaded AC outlets and extension cords are
dangerous, as are frayed power cords and broken plugs,
which may cause electric shock or fire. Call your service
technician for replacement.
Do not use sharp tools such as a pin or a pencil near
the monitor, as they may scratch the LCD surface.
Do not use a solvent, such as benzene,
to clean the monitor, as it will damage the LCD surface.
Cleaning and maintenance
• To avoid risk of electric shock, do not disassemble the display unit cabinet. The
unit is not user-serviceable. Remember to unplug the display unit from the power
outlet before cleaning.
• Do not use alcohol (methyl, ethyl or isopropyl) or any strong dissolvent. Do not use
thinner or benzene, abrasive cleaners or compressed air.
• Do not wipe the screen with a cloth or sponge that could scratch the surface.
• To clean your antistatic screen, use water and a special microfiber screen cleaning
tissue used in optical lens cleaning, or lightly dampen a soft, clean cloth with water
or a mild detergent.
• If the instructions above do not help in removing stains, contact an authorized
service agent.

such as a window.
• Position the monitor so that the top of the screen is no higher than eye level.
• Position the monitor directly in front of you at a comfortable reading distance
(around 45 to 90cm)
Connecting the monitor
Before you start cabling your monitor, check that the
power is off on all units. To avoid any possibility of
electric shock, always connect your equipment to
properly earthed outlets.
