SAFETY PRECAUTIONS

WARNING: The following precautions must be observed.

ALL PRODUCTS

Before any service is performed on the chassis an isolation transformer should be inserted between the power line and the product.

1. When replacing the chassis in the cabinet, ensure all the protective devices are put back in place.

2. When service is required, observe the original lead dressing. Extra precaution should be taken to ensure correct lead dressing in any high voltage circuitry area.

3. Many electrical and mechanical parts in HITACHI products have special safety related characteristics. These characteristics are often not evident from visual inspection, nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified by marking with a

! on the schematics and the replacement parts list. The use of a substitute replacement component that does not have the same safety characteristics as the HITACHI recommended replacement one, shown in the parts list, may create electrical shock, fire, X-radiation, or other hazards.

4. Always replace original spacers and maintain lead lengths. Furthermore, where a short circuit has occurred, replace those components that indicate evidence of overheating.

5. Insulation resistance should not be less than 2M ohms at 500V DC between the main poles and any accessible metal parts.

6. No flashover or breakdown should occur during the dielectric strength test, applying 3kV AC or

4.25kV DC for two seconds between the main poles and accessible metal parts.

7. Before returning a serviced product to the customer, the service technician must thoroughly test the unit to be certain that it is completely safe to operate without danger of electrical shock. The service technician must make sure that no protective device built into the instrument by the manufacturer has become defective, or inadvertently damaged during servicing.

CE MARK

1. HITACHI products may contain the CE mark on the rating plate indicating that the product contains parts that have been specifically approved to provide electromagnetic compatibility to designated levels.

2. When replacing any part in this product, please use only the correct part itemised in the parts list to ensure this standard is maintained, and take care to replace lead dressing to its original state, as this can have a bearing on the electromagnetic radiation/immunity.

PICTURE TUBE

1. The line output stage can develop voltages in excess of 25kV; if the E.H.T. cap is required to be removed, discharge the anode to chassis via a high value resistor, prior to its removal from the picture tube.

2. High voltage should always be kept at the rated value of the chassis and no higher. Operating at higher voltages may cause a failure of the picture tube or high voltage supply, and also, under certain circumstances could produce X-radiation levels moderately in excess of design levels. The high voltage must not, under any circumstances, exceed 29kV on the chassis (except for projection Televisions).

3. The primary source of X-radiation in the product is the picture tube. The picture tube utilised for the above mentioned function in this chassis is specially constructed to limit X-radiation. For continued X-radiation protection, replace tube with the same type as the original HITACHI approved type

4. Keep the picture tube away from the body while handling. Do not install, remove, or handle the picture tube in any manner unless shatterproof goggles are worn. People not so equipped should be kept away while picture tubes are handled

LASERS

If the product contains a laser avoid direct exposure to the beam when the cover is open or when interlocks are defeated or have failed.

Note 6

Note 1) Viewing Angle is the angle at which the contrast ratio is greater than 10. Viewing is

determined for the horizontal or 3 & 9 o’clock direction and the vertical or 6 & 12 o’clock direction with respect to the optical axis which is normal to the LCD surface.

Note 2) Contrast measurements shall be made at viewing angle of θ = 0° and at the centre of the

LCD surface. Luminance shall be measure with all pixels in the view field set first to white, then to the dark (black) state. Luminance Contrast Ratio (CR) is defined mathematically.

Luminance when displaying a white raster

CR=  Luminance when displaying a black raster

Note 3) Centre Luminance of white is defined as LCD surface. Luminance shall be measured

with all pixels in the view field set first to white. This measurement shall be taken at the locations shown in figure 2 for a total of the measurements per display.

Note 4) The White luminance uniformity on LCD surface is then expressed as: Y= maximum

Luminance of five points / Minimum Luminance of five points

Note 5) Colour chromaticity co-ordinate specified shall be calculated from the spectral data

measured with all pixels first in red, green, blue and white. Measurements shall be made at the centre of the panel.

Note 6) The electro-optical response time measurements shall be made as figure by switching the

“data” input signal ON and OFF. The times needs for the luminance to change from 10% to 90% is Td, and 90% to 10% is Tr.

Note 7) Cross-Talk of one area of the LCD surface by another shall be measured by comparing

the luminance (Y the luminance (Y

) of a 25 mm diameter area, with all display pixels set to a grey level to

) of that same area when any adjacent is driven dark.

If the input timing is not a timing listed above but within the supported frequency range (Horizontal: 80KHz,Vertical: 75Hz), this monitor will select a closest mode instead. But the display quality may not be optimised. If the input timing over the supported frequency range a message “Input Signal Out of Range” will be shown.

 Other Features:

 Intellectual-Auto unit can start the Auto-Adjustment automatically when input a new

display mode at first time. After the adjustment, the unit will remember this mode and switch to optimised condition automatically for this mode whenever encounter this mode again. Total 27 recent used modes are recorded into the unit.

 VESA DPMS Functionality When signaled by the host CPU, the unit shows a black

screen about 3 seconds. If no further signal, then it shows “No Signal” and enter power saving mode.

2.6 White Colour Temperature

White colour temperature is 4 preset as 9300, 7500, 6500 and User, Default value of user colour should be user which is maximum setting for panel.

2.7 POWER SUPPLY

2.7.1 Input Voltage Range

The monitor shall operate within specification over the range of 90 to 265VAC power supply.

2.7.2 Input Frequency Range

Input power frequency range shall be from 47.5 to 63Hz over the specified input voltage range.

2.7.3 Quick Specification Review

• Input Current

1.2A (max) at 90VAC input and full load

0.6A (max) at 264VAC input and full load.

• Inrush Current @ cold start

30A(0-peak) @ 110Vac, 50A (0-peak) @ 220Vac

(measured when switched off for at least 10 mins.)

• Output

Tolerance Output Current

+5Vdc ±5% 0A 1.0A

+5Vdc ±5% 0A 1.5A 4.8~5.2V dc

+12Vdc +25%/-5% 0A 2.2A 11.4~15Vdc

• Total Output Power: 48 Watt max.

• Withstanding Voltage: 1.5Kvac or 2.2KVdc for 1 minute.

• Leakage Current: < 0.25mA/100Vac, <3.5mA/230Vac

• Efficiency: 70% min. @15V/230VAC, maximum load.

2.7.4 Power Management

2.7.4.1 Meets VESA DPMS Proposal

The monitor must comply with the Microsoft On Now specification, with a minimum of three power management states, as defined by the VESA DPMS document. The front panel of the monitor must appropriately display the DPMS state, For example:

Volt Tolerance

4.8~5.2Vdc (for Audio)

DPMS ON : The power LED is Green DPMS OFF : The power LED is Amber

2.7.5 Power Consumption

On mode 48 Wmax Green Off mode 4 Wmax Amber

DC power off 4 Wmax Dark

Power SW off 1 Wmax Dark

Disconnection 4 Wmax

Dark (DC power off) Amber (DC power on)
