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

Half Sine Wave Shock: 120G peak, half sine pulse, 2ms pulse duration. Testing shall
consist of one shock in each direction in each axis, for a total of 6 shock inputs.
Square Wave Shock: 40G peak acceleration, 160 inches / second velocity change. There
shall be one shock in each direction in each axis, for a total of 6 shock inputs.

Transients/Burst)
TEST CONDITIONS & PROCEDURE: (Follow IEC 61000-4-4)
Test Condition :
The condition is base on operating with 50Ω load.
8.1 Peak Voltage:
2 KV (applies the Level 3 typical Industrial Environment” of IEC 61000-4-4)
8.2 Polarity : + / -
8.3 Repetition Frequency of the impulse: 5 KHz.
±±±±
8.4 Rise-Time: 5ns
8.5 Impulse Duration: 50 nS
8.6 Relation to Power Supply: Asynchronous

8.7 Burst Duration: 15 ms
8.8 Burst Period: 300 ms
8.9 Climatic Conditions:
- Ambient Temperature: 15°C to 35°C
- Relative Humidity: 45% to 75%
- Atmospheric Pressure: 86KPa to 106KPa
8.10 Test Procedure:
The monitor Display set high-resolution mode, AC input is AC 240V.
Note :
8.10.1
IEC 61000-4-4 defines that power supply, I/O line and control line all shall perform the
transient test. The I/O line and control line is applied with only half of peak voltage (1
KV).
8.10.2
For the comparison of wave-shape generated by different generator, so the test must uses a
scope with at least 400 MHz bandwidth, and coupled to 50Ω to monitor the rise-time,
impulse, duration and repetition rate of the impulses within one burst.

9.3
The surge will be applied between lines and between lines and ground.
9.4
If not otherwise specified, the surge to power supply circuits shall be applied synchronised to
the voltage phase at the zero crossing and the peak value of the AC voltage wave. (Positive
and negative)
9.5
The surge voltage for test is from 1KV and increases 1KV for each step.
9.6
The recommended severity levels for the surge voltage test is 2.0KV and without any
degradation or loss of function that is not recoverable due to damage of component or
software allowed.
9.7 Display set high-resolution mode, AC input is AC 240V.
