correct this, turn the monitor off for 20 minutes before powering it back on.

• When operating the Diamond Plus 74

SB

with its AC 220-240V worldwide power supply, use a
power supply cord that matches the power supply voltage of the AC power outlet being used. The
power supply cord you use must have been approved by and comply with the safety standards of
your country. (Type H05VV-F should be used except in UK)

• In UK, use a BS-approved power cord with molded plug having a black (5A) fuse installed for use with
this monitor. If a power cord is not supplied with this monitor, please contact your supplier.

Cleaning Your Monitor

A special coating is provided on the glass (CRT) surface of this monitor to reduce a reflection and
static electricity on the glass surface. Due to the delicate coating on the glass surface, use a lint-free,
non-abrasive cloth (cotton or equivalent) and a non-alcohol, neutral, non-abrasive cleaning solution
to minimize dust. If the screen requires more than a light cleaning, apply a soft neutral detergent and
water directly to a soft cloth and use it upon wringing water, to clean the glass surface. Clean your
monitor regularly.

CAUTION:

The following agents will cause damage to the CRT when cleaning the glass surface:
Benzene, thinner, acid/alkaline detergent, alcohol detergent, detergent with abrasive powder,
detergent with anti-static agent, detergent for cleaning.

Immediately unplug your monitor from the wall outlet and refer servicing to qualified service personnel
under the following conditions:

• When the power supply cord or plug is damaged.

• If liquid has been spilled, or objects have fallen into the monitor.

• If the monitor has been exposed to rain or water.

• If the monitor has been dropped or the cabinet damaged.

• If the monitor does not operate normally by following operating instructions.

• Allow adequate ventilation around the monitor so that heat can properly

dissipate. Do not block ventilated openings or place the monitor near a
radiator or other heat sources. Do not put anything on top of monitor.

• The power cable connector is the primary means of detaching the system
from the power supply. The monitor should be installed close to a power
outlet which is easily accessible.

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR

CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE

FOLLOWING WHEN YOU POSITION THE MONITOR:

Recommended Use

–continued

• Adjust the monitor height so that the top of
the screen is at or slightly below eye level.
Your eyes should look slightly downward
when viewing the middle of the screen.

• Position your monitor no closer than 16 inches
and no further away than 24 inches from your
eyes. The optimal distance is 20 inches.

• Rest your eyes periodically by focusing on
an object at least 20 feet away. Blink often.

• Position the monitor at a 90° angle to
windows and other light sources to minimize
glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect
on your screen.

• If reflected light makes it hard for you to see your screen, use an anti-glare filter.

• Clean your monitor regularly. Use a lint-free, non-abrasive cloth and a

non-alcohol, neutral, non-abrasive cleaning solution or glass cleaner to
minimize dust.

• Adjust the monitor’s brightness and contrast controls to enhance readability.

• Use a document holder placed close to the screen.

• Position whatever you are looking at most of the time (the screen or

reference material) directly in front of you to minimize turning your head
while you are typing.

• Get regular eye checkups.

Ergonomics

To realize the maximum ergonomics benefits, we recommend the following:

• Adjust the Brightness until the background raster disappears

• Do not position the Contrast control to its maximum setting

• Use the preset Size and Position controls with standard signals

• Use the preset Color Setting and Sides Left/Right controls

• Use non-interlaced signals with a vertical refresh rate between 75-120Hz

• Do not use primary color blue on a dark background, as it is difficult to see
and may produce eye fatigue due to insufficient contrast

respect to recommended timings and pin assignments.

•

If the Macintosh cable adapter is used, check for proper connection or make sure the
display card is Macintosh compatible and that the card is properly seated in the computer

.

LED on monitor is not lit

(no green, orange color can be seen)

• Power Switch should be in the ON position and power cord should be connected.

LED on monitor is flashing and/or dissapears

• Contact Customer Service at [phone].

Picture is fuzzy or color looks blotchy

• Adjust Brightness and Contrast Controls or adjust the Moiré Canceler control.

• Access the Degauss Control through OSM™ controls. Activate the Degauss Control.

CAUTION: A minimum interval of 20 minutes should elapse before the Deguass
Control is used a second time when not switching between modes.

Picture bounces or a wavy pattern is present in the picture

•

Move electrical devices that may be causing electrical interference away from the monitor.

• See inside cover of User’s Manual for FCC information.

Edges of the display image are not square

• Use the OSM Geometry Controls to straighten the edges.

• If possible, position the front of the monitor facing east.

Display image is not centered, too small, or too large

• Use the OSM Size and Position Controls to adjust the image.

Thin lines appear on your screen

• Thin lines are normal for an aperture grille CRT and are not a malfunction.

These are shadows from the damper wires used to stabilize the aperture grille and
are most noticeable when the screen’s background is light (usually white).

Black vertical lines are visible on the screen

• Thin vertical black lines on one or both sides of the screen. This minor condition is

caused by grille element overlap which can occur during shipping.

• Position an open white window over the affected area of the screen and maximize

the brightness and contrast controls. This will cause localized heating of the overlap
which will clear in a few minutes. Be sure to readjust the brightness and contrast
controls back to the normal viewing level after this procedure.

TCO’95

Diamond Plus 74SB Black Model

Congratulations! You have just purchased a TCO’95 approved and
labeled 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’95 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.
TCO’95 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 circuit 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

1-19

17

toxins, PCBs, which are suspected to give rise to similar harm, including reproductive damage in
fisheating 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’95 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’95 requirement permits the inclusion of lead since no replacement has yet been developed.

Cadmium**

Cadmium is present in rechargeable batteries and in the colourgenerating layers of certain
computer displays. Cadmium damages the nervous system and is toxic in high doses.
TCO’95 requirement states that batteries may not contain more than 25 ppm (parts per million) of
cadmium. The colourgenerating 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’95 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. 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)

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’95 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.

• DO NOT OPEN THE MONITOR. There are no user serviceable parts inside and opening or removing covers

may expose you to dangerous shock hazards or other risks. Refer all servicing to qualified service personnel.

• Do not spill any liquids into the cabinet or use your monitor near water.

• Do not insert objects of any kind into the cabinet slots, as they may touch dangerous voltage points, which

can be harmful or fatal or may cause electric shock, fire or equipment failure.

• Do not place any heavy objects on the power cord. Damage to the cord may cause shock or fire.

• Do not place this product on a sloping or unstable cart, stand or table, as the monitor may fall, causing

serious damage to the monitor.

• Keep the monitor away from high capacity transformers, electric motors and other devices such as external

speakers or fans, which may create strong magnetic fields.

• If possible, position the monitor so that it is facing the east to minimize the effects of the earth’s magnetic

field.

• Changing the direction of the monitor while it is powered on may cause image discolouration. To correct this,

turn the monitor off for 20 minutes before powering it back on.

• When operating the Diamond Plus 74

SB

with its AC 220 - 240 V worldwide power supply, use a power supply
cord that matches the power supply voltage of the AC power outlet being used. The power supply cord you
use must have been approved by and comply with the safety standards of your country. (Type H05VV-F
should be used except in UK)

• In UK, use a BS-approved power cord with molded plug having a black (5A) fuse installed for use with this

monitor. If a power cord is not supplied with this monitor, please contact your supplier.

Cleaning Your Monitor

A special coating is provided on the glass (CRT) surface of this monitor to reduce a reflection and static
electricity on the glass surface. Due to the delicate coating on the glass surface, use a lint-free, non-abrasive
cloth (cotton or equivalent) and a non-alcohol, neutral, non-abrasive cleaning solution to minimize dust. If the
screen requires more than a light cleaning, apply a soft neutral detergent and water directly to a soft cloth and
use it upon wringing water, to clean the glass surface. Clean your monitor regularly.

CAUTION:

The following agents will cause damage to the CRT when cleaning the glass surface:
Benzene, thinner, acid/alkaline detergent, alcohol detergent, detergent with abrasive powder, detergent with
anti-static agent, detergent for cleaning.

Immediately unplug your monitor from the wall outlet and refer servicing to qualified service personnel under
the following conditions:

• When the power supply cord or plug is damaged.

• If liquid has been spilled, or objects have fallen into the monitor.

• If the monitor has been exposed to rain or water.

• If the monitor has been dropped or the cabinet damaged.

• If the monitor does not operate normally by following operating instructions.

• Allow adequate ventilation around the monitor so that heat can properly
dissipate. Do not block ventilated openings or place the monitor near a radiator
or other heat sources. Do not put anything on top of monitor.

• The power cable connector is the primary means of detaching the system from
the power supply. The monitor should be installed close to a power outlet which
is easily accessible.

• Handle with care when transporting. Save packaging for transporting.

Recommended Use

– continued

• Adjust the monitor height so that the top of the screen is at or slightly

below eye level. Your eyes should look slightly downward when viewing the
middle of the screen.

• Position your monitor no closer than 40 cm and no further away than

60 cm from your eyes. The optimal distance is 50 cm.

• Rest your eyes periodically by focusing on an object at least 6 meter away.

Blink often.

• Position the monitor at a 90° angle to windows and other light sources to

minimize glare and reflections. Adjust the monitor tilt so that ceiling lights
do not reflect on your screen.

• If reflected light makes it hard for you to see your screen, use an anti-glare

filter.

• Clean your monitor regularly. Use a lint-free, non-abrasive cloth and a non-alcohol, neutral, non-abrasive

cleaning solution or glass cleaner to minimize dust.

• Adjust the monitor ’s brightness and contrast controls to enhance readability.

• Use a document holder placed close to the screen.

• Position whatever you are looking at most of the time (the screen or reference material) directly in front of

you to minimize turning your head while you are typing.

• Get regular eye checkups.

Ergonomics

To realize the maximum ergonomics benefits, we recommend the following:

• Adjust the Brightness until the background raster disappears

• Do not position the Contrast control to its maximum setting

• Use the preset Size and Position controls with standard signals

• Use the preset Colour Setting and Sides Left/Right controls

• Use non-interlaced signals with a vertical refresh rate between 75 - 120 Hz

• Do not use primary colour blue on a dark background, as it is difficult to see and may produce eye fatigue
due to insufficient contrast

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR

CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE

User’s Manual

No picture

• Display card should be completely seated in its slot.

• Power Button and computer power switch should be in the ON position.

• Signal cable should be completely connected to display card/computer.

• Check connector for bent or pushed-in pins.

Image is scrolling or unstable

• Signal cable should be completely attached to the computer.

• Check pin assignments and signal timings of the monitor and your display card with respect to
recommended timings and pin assignments.

• If the Macintosh cable adapter is used, check for proper connection or make sure the display card is
Macintosh compatible and that the card is properly seated in the computer.

LED on monitor is not lit

(no green, orange colour can be seen)

• Power Switch should be in the ON position and power cord should be connected.

Picture is fuzzy or colour looks blotchy

• Adjust Brightness and Contrast Controls or adjust the Moiré Canceler control.

• Access the Degauss Control through OSM controls. Activate the Degauss Control.
CAUTION: A minimum interval of 20 minutes should elapse before the Deguass Control is used a second
time when not switching between modes.

Picture bounces or a wavy pattern is present in the picture

• Move electrical devices that may be causing electrical interference away from the monitor.

• See inside cover of User’s Manual for FCC information.

Edges of the display image are not square

• Use the OSM Geometry Controls to straighten the edges.

• If possible, position the front of the monitor facing east.

Display image is not centered, too small, or too large

• Use the OSM Size and Position Controls to adjust the image.

Thin lines appear on your screen

• Thin lines are normal for an aperture grille CRT and are not a malfunction.
These are shadows from the damper wires used to stabilize the aperture grille and are most noticeable when
the screen’s background is light (usually white).

Black vertical lines are visible on the screen

• Thin vertical black lines on one or both sides of the screen. This minor condition is caused by grille element
overlap which can occur during shipping.

• Position an open white window over the affected area of the screen and maximize the brightness and
contrast controls. This will cause localized heating of the overlap which will clear in a few minutes. Be sure
to readjust the brightness and contrast controls back to the normal viewing level after this procedure.

Congratulations! You have just purchased a TCO’99 approved and labeled 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), Svenska Naturskyddsforeningen (The Swedish Society for Nature
Conservation) and Statens Energimyndighet (The Swedish National Energy Administration).

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.

Environmental Requirements

Flame retardants

Flame retardants are present in printed circuit 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.
Most flame retardants contain bromine or chloride and these are related to another group of environmental toxins,
PCBs, which are suspected to give rise to severe health effects, including reproductive damage in fisheating 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 occur.

User’s Manual

TCO’99 demand requires that plastic components weighing more than 25 grams must not contain flame retar­dants with organically bound chlorine and bromine. Flame retardants are allowed in the printed circuit boards
since no substitutes are available.

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 colourgenerating layers of certain computer displays.
Cadmium damages the nervous system and is toxic in high doses.

TCO’99 requirement states that batteries, the colourgenerating 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, Mercury damages the nervous system and is toxic
in high doses.

TCO’99 requirement states that batteries may not contain any Mercury. It also demands that no mercury is
present in any of the electrical or electronics components associated with the display unit.

CFCs (freons)

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 conse­quent increased risks of skin cancer (malignant melanoma).

The relevant TCO’99 requirement; Neither CFCs nor HCFCs may be used during the manufacturing and assembly
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.

* Notes About Degaussing Method

Follow the degaussing procedure as below. (For prevent intertwinement of aperture grille.)

1) Use stick type degaussing probe at demagnetizing CRT.
Do not use ring type degaussing probe.

2) In order to remove a magnetization from front, top, bottom and side of CRT, and bottom chassis.
Do not switch off the degaussing probe abruptly. Move the degaussing probe slowly when degaussing.

Note: If switch off the degaussing probe near the set, the set will be magnetized.

3) Degaussing method

When switch on the degaussing probe, keep distance between panel surface and degaussing probe more than
50cm. Move the degaussing probe vertically facing to the panel surface.

Keep distance of panel surface and degaussing probe to more than 15mm.

Starting from edge of CRT, move the degaussing probe toward CRT center in circular motion, spending 6 to 7
seconds. (Rounding about 4 or 5 times.)

Ver ti cal

Horizontal

4) After sufficiently degaussing the CRT, move the degaussing probe slowly away from the panel surface

while rotating from corner to center, taking more than 3 seconds. Turn off SW more than 1m away from
the CRT. Degauss again if the unit is magnetized.

3.3 Video Performance

Video Clock Frequency 120MHz (Input signal)
Pulse Rise and Fall time 9.0nsec (typ.) 10 to 90% at 40Vp-p

The rise and fall time of the input video signal is 2.0nsec or less.

The pulse rise or fall time is determined using the formula :

)(

2222

TscTpTsTmTa ++−=

Where : Ta = Amplifier rise / fall time

Tm = Measured rise / fall time

Ts = Input signal rise / fall time

Tp = Probe effect on rise / fall time = 2.2 x Rl x Cp

Rl = Amplifier output resistance (ohm)

Cp = Total probe capacitance (F)

Tsc= Scope rise / fall time = 0.35 / Scope bandwidth (MHz)
