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 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 (The Swedish Society
for Nature Conservation) and Statens Energimyndighet (The Swedish National Energy Administration).
Approval requirements 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 impose 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 policy 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.
Below you will find a brief summary of the environmental requirements met by this product. The complete
environmental criteria document may be ordered from:

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.
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 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 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

**

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.

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

**

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 developed.

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

** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.

smoky areas as it may cause fire, electric shock or damage. You should also avoid areas where
the sun shines directly on the monitor.

DO NOT PLACE THE MONITOR IN A HAZARDOUS POSITION

The monitor may topple and cause injury if not suitably located. Please also ensure that you do not
place any heavy objects on the monitor, and that all cables are routed such that children may not
pull the cables and possibly cause injury.

FOR YOUR SAFETY 1

PROTECT THE CABLES

Do not pull or bend the power cable and signal cable. Do not place the monitor or any other heavy
objects on the cables. If damaged, the cables may cause fire or electric shock.

ADVERSE WEATHER CONDITIONS

It is advisable not to operate the monitor during a heavy thunder storm as the continual breaks in
power may cause malfunction. It is also advised not to touch the plug in these circumstances as
it may cause electric shock.

ENGLISH

CAUTION

MAINTAIN GOOD VENTILATION

Ventilation slots are provided to keep the monitor from overheating. Covering the slots may cause
fire. To allow adequate air circulation, place the monitor at least 10 cm (or 4 inches) from any walls.
Do not remove the tilt stand when operating the monitor. Ventilation slots on the cabinet bottom will
be blocked and the monitor may overheat if the stand is removed. This may cause fire or damage.
Operating the monitor on its back, side, upside down or on a carpet or any other soft material may
also cause damage.

DISCONNECT THE CABLES WHEN YOU MOVE THE MONITOR

When you move the monitor, turn off the power switch, unplug the monitor and be sure the signal
cables are disconnected. If you do not disconnect them, it may cause fire or electric shock.
It is recommended that two people are used when moving the monitor.

UNPLUG THE MONITOR

If the monitor is not in use for a long period of time it is recommended that it is left unplugged to avoid
accidents.

HOLD THE PLUG WHEN DISCONNECTING

To disconnect the power cable or signal cable, always pull it by the plug. Never pull on the cable
itself as this may cause fire or electric shock.

DO NOT TOUCH THE PLUG WITH WET HANDS

Pulling or inserting the plug with wet hands may cause electric shock.

DO NOT PUT FLOPPY DISKS NEAR THE MONITOR

Magnetic data recordings such as on a floppy disk may disappear if they are placed on or near the
monitor as the degauss circuit causes a strong momentary magnetic field.

WHEN YOU INSTALL THE MONITOR ON YOUR COMPUTER

Be sure the computer is strong enough to hold the weight of the monitor, otherwise, you may
damage your computer.

OTHERS

ERGONOMIC RECOMMENDATIONS

To eliminate eye fatigue, do not operate the monitor against a bright background or in a dark room.
For optimal viewing comfort, the monitor should be just below eye level and 40-60 cm (16-24
inches) away from your eyes. When using the monitor over a prolonged time, a ten minute break
every hour is recommended as looking at the screen continuously can cause eye strain.

12 OPERATING THE MONITOR

Even when using the power management mode, the monitor consumes electricity. Turn
off the Power Switch whenever the monitor is not used, during the night and weekends,
to avoid unnecessary power consumption.

NOTE

Stand-by Mode
When the H-sync signal from the computer is off, the monitor enters into Stand-by Mode which
reduces the power consumption to less than 15W. The screen becomes dark, and the power
indicator turns to orange. From Stand-by Mode, the screen reappears instantaneously when
the keyboard or the mouse is touched again.

Suspend Mode
When the V-sync signal from the computer is off, the monitor enters into Suspend Mode which
reduces the power consumption to less than 15W. The screen becomes dark, and the power
indicator turns to orange. From Suspend Mode, the screen reappears instantaneously when
the keyboard or the mouse is touched again.

Active-off Mode
When the H and V sync signals from the computer are off, the monitor enters into Active-off
Mode which reduces the power consumption to less than 3W. The screen becomes dark, and
the power indicator turns to orange. From Active-off Mode, the screen reappears in 10 seconds
when the keyboard or the mouse is touched again.

The power management feature of this product complies with every power saving requirement of
ENERGY STA R®, VESA DPMS and Nutek 803299. When activated, it automatically reduces
unnecessary power consumption of the monitor when your computer is not in use.
To use the feature, the monitor needs to be connected to a VESA DPMS compliant computer. These
are the three power management steps the monitor takes as described below. The required
settings, including the timer setting, should be made by the computer.

TROUBLE SHOOTING 13

ENGLISH

Normal phenomenon on ‘DiamondtronTM NF’ monitors

Misalignment of Aperture Grille

Due to the nature of the DiamondtronTM NF CRT, in rare cases, a misalignment of the aperture grille
may happen by the shock or vibration caused during transportation. If a black vertical line appears
on the screen, apply a light shock to the side of the monitor with your hand. If the problem persists,
follow the procedure below.

Display a full white picture and inspect the problem area.
Display a high-white picture that covers the problem area to shoot a strong electron beam.
Leave it for a while, until the problem disappears.

Damper Wires

The two faint horizontal lines that may be visible on the screen are actually the shadows of steel

wires called

Damper Wires. All DiamondtronTM NF CRT based monitors have these wires for

structural reasons.
