The SERVICE PERSONNEL should have the appropriate technical training, knowledge and experience necessary to:

• Be familiar with specialized test equipment, and

• Be careful to follow all safety procedures to minimize danger to themselves and their coworkers.

To avoid electrical shocks, this equipment should be used with an appropriate power cord. This equipment utilized a micro-gap power switch. Turn off the set by first pushing power switch. Next,

remove the power cord from the AC outlet. To prevent fire or shock hazards, do not expose this unit to rain or moisture. This symbol warns the personnel that un-insulated voltage within the unit may have sufficient magnitude to cause electric shock.

This symbol alerts the personnel that important literature concerning the operation and maintenance of this unit has been included. Therefore, it should be read carefully in order to avoid any problems.

WARNING

PRODUCT SAFETY CAUTION

1. When parts replacement is required for servicing, always use the manufacturer's specified replacement.

2. When replacing the component, always be certain that all the components are put back in the place.

3. As for a connector, pick and extract housing with fingers properly since a disconnection and improper contacts may occur, when wires of the connector are led.

4. Use a proper screwdriver. If you use screwdriver that does not fit, you may damage the screws.

Image Persistenc

Image persistence is when a residual or “ghost” image of a previous image remains visible on th screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant image being displayed for a long period of time should be avoided

alleviate image persistence, turn off the monitor for as long as the previous image was displayed For example, if an image was on the monitor for one hour and a residual image remains, the monito should be turned off for one hour to erase the image

moving screen saver at regular intervals whenever the screen is idle or turning off the monitor whe not in use

Congratulations! You have just purchased a TCO’99 approved an

abelled product! Your choice has provided you with a product develope

or professional use. Your purchase has also contributed to reducing th burden on the environment and also to the further development o environmentally adapted electronics products

Why do we have environmentally labelled computers

In many countries, environmental labelling has become an established method for encourag ing the adaptation of goods and services to the environment. The main problem, as far a computers and other electronics equipment are concerned, is that environmentally harmfu substances are used both in the products and during the manufacturing. Since it has not bee possible for the majority of electronics equipment to be recycled in a satisfactory way, mos of these potentially damaging substances sooner or later enter Nature

There are also other characteristics of a computer, such as energy consumption levels, that ar 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 th environment (acidic and climate-influencing emissions, radioactive waste, etc.), it is vital t conserve energy. Electronics equipment in offices consume an enormous amount of energ 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 an environmental labelling of personal computers. The labelling scheme was developed as a join effort by the TCO (The Swedish Confederation of Professional Employees), Svensk Naturskyddsforeningen (The Swedish Society for Nature Conservation) and Statens Energimyndighe (The Swedish National Energy Administration)

The requirements cover a wide range of issues: environment, ergonomics, usability, emission o 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 othe things. The product must be prepared for recycling and the manufacturer is obliged to have a environmental plan which must be adhered to in each country where the company implements it 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 o 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 reductio of electric and magnetic fields, physical and visual ergonomics and good usability

Environmental Requirement

Flame retardant

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 o

lame retardant substances. Most flame retardants contain bromine or chloride and these ar related to another group of environmental toxins, PCBs, which are suspected to give rise to sever health effects, including reproductive damage in fisheating birds and mammals, due to the bio

accumulative* processes. Flame retardants have been found in human blood and researchers fea that disturbances in foetus development may occur

TCO’99 demand requires that plastic components weighing more than 25 grams must not contai

lame retardants with organically bound chlorine and bromine. Flame retardants are allowed i the printed circuit boards since no substitutes are available

–continue

Lead*

Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages th 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 color generating layers of certain compute

isplays. Cadmium damages the nervous system and is toxic in high doses

TCO’99 requirement states that batteries, the color generating layers of display screens and th electrical or electronics components must not contain any cadmium

ercury**

Mercury is sometimes found in batteries, relays and switches, Mercury damages the nervous syste and is toxic in high doses

TCO’99 requirement states that batteries may not contain any Mercury. It also demands that n mercury is present in any of the electrical or electronics components associated with the display unit

(freons)

CFCs (freons) are sometimes used for washing printed circuit boards. CFCs break down ozone an thereby damage the ozone layer in the stratosphere, causing increased reception on Earth o 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 manufacturin 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

Safety Precautions and Maintenance

FOR OPTIMUM PERFORMANCE, PLEASE NOTE

THE FOLLOWING WHEN SETTING UP AND

USING THE ACCUSYNC LCD COLOUR MONITOR:

• 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.

• When operating the LCD monitor with its AC 125-240V power supply, use a power supply aord 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 in Europe).

• In U.K, 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.

• Do not place any objects onto the monitor and do not use the monitor outdoors.

• The inside of the fluorescent tube located within the LCD monitor contains mercury. Please follow the bylaws or rules of

your municipality to dispose of the tube properly.

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.

• Do not bend power cord.

• Do not use monitor in high temperature, humid, dusty, or oily areas.

• Do not cover vent on monitor.

• If monitor is broken, do not come in contact with the liquid crystal and handle with care.

• 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

CAUTION

• Image Persistence: Image persistence is when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.

NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display-Europe recommends using a moving

screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.

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.

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR CAN

REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE

FOLLOWING WHEN YOU POSITION THE MONITOR:

• For optimum performance, allow 20 minutes for warm-up.

• 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 70 cm from your eyes. The optimal distance is 58 cm.

• Rest your eyes periodically by focusing on an object at least 6 m 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 antiglare filter.

• Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner!

• 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.

• Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after-image effects).

• Get regular eye checkups.

Ergonomics

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

• Use the preset Size and Position controls with standard signals.

• Use the preset Colour Setting.

• Use non-interlaced signals with a vertical refresh rate between 60-75 Hz.

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

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), 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. 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. To obtain complete information on the environmental criteria document, order from:

4. Safety Test

• Destination : All over the world

• Applicable standards : UL60950/C-UL/EN60950

• Unit class : Class I units (the units protected against electric shocks by protective

earthing, or those equipped with 3-core power cords)

• Ratings : AC100 - 240V 50/60Hz 0.75A/0.4A

4.1 Input Current Measurements

Under the measuring conditions specified below, an input current should be measured while the 50Hz input

voltage is maintained at 220V AC (+0 to -5V). The input currents measured should all confirm so they satisfy

the judgment standard. (The rear rating plates are the same as those for North America and Europe.

Therefore, measurements should also be based on this setting.)

(1) Measuring conditions

• Condition of the set : ON mode

• Measuring conditions : The inspection signal is set at “17” and “white” is displayed throughout

the screen.

At that time, the brightness and contrast should be kept under the brightest condition.

(2) Judgment standard

• The input current should be kept below 0.35A +10%.

4.2 Power Source/Earth Connections

a. Checks on the power source/earth connections

The earth side of the cord or the earth wire of the inlet filter for the cord set should be visually checked to

see that it is connected to the chassis block of the unit as specified below.

1) The earth wire color should be spiral of green and yellow.

[Units applicable to UL60950 or IEC60950 (EN60950)]

2) The earth wire should be firmly connected to the chassis block by the use of a screw (See Note) of

3.5mm∅ in diameter.

Note: Spring washers or star washers should be used, without fail.

b. Earth resistance testing

This testing should be carried out prior to the dielectric strength test.

The earth resistance should be 0.1Ω or less when a current of 25A AC is carried between the earth side

of the cord (the plug block or the section closest to the plug where no plug is provided) and the metallic

block (the D-SUB connector) that is used as a safety earth for the unit.

Where the earth resistance exceeds 0.1Ω, the condition should be still acceptable if the earth resistance

is 0.1Ω or less when the resistance of the power cord is excepted.

5-13

4.3 Dielectric Strength Test

To confirm the freedom from insulation breakdown, testing should be carried out under the conditions

specified below.

1) Measuring conditions

• Measuring instrument: Dielectric strength tester (The specified voltage should be maintained in the

state that a current of 10mA is carried.)

• Testing point: Between the electrical circuit block and the exposed metallic block (D-SUB

connector)

Note: The electrical circuit block should mean the power input block (primary side). Testing should be

carried out under the condition that both poles of the power plug are short-circuited. (Where a

3-core cord is used, the two poles other than the earth terminal should be short-circuited.)

2) Judgment standard

The freedom from insulation breakdown should be confirmed under the condition that the applied

voltage is maintained at 1500V AC (+0 to 50V) for one minute.

Even though the result of this testing is OK, such a condition should be regarded as unacceptable if

there is a leakage (flashing) around the section where the test voltage has been applied.

If the result of insulation resistance test is found unacceptable, to be carried out after this testing, such

a condition should be regarded as that an insulation breakdown has occurred.

4.4 Leakage Current Test

A leakage current should be measured under the conditions specified below, in order to confirm that the

requirements of the judgment standard are met.

1) Measuring conditions

• Measuring instrument: Leakage current meter (A 1500Ω resistor should be incorporated,

together with a bypass capacitor of 0.15µF.)

• Testing point: Between the exposed metallic block (D-SUB connector) and Phases

A and B of the power source.

• Condition of the set: A power cable should be connected. The see-saw switch on the set side

should be turned ON and OFF.

2) Judgment standard

The leakage current measured should be 1.5mA or less with an input of 240V AC × 1.06 +5/-0V (60Hz).

5-14

4.5 Insulation Resistance Test

An insulation resistance should be measured under the conditions specified below, in order to confirm that

the requirements of the judgment standard are met.

1) Measuring conditions

• Measuring instrument: 500V DC MEGOHM Meter

• Testing point: Between the power circuit block and the exposed metallic block

(D-SUB connector)

• Measured value readout: A test voltage should be applied for one minute and the resistance

value should be read out thereafter.

2) Judgment standard: 10MΩ or more
