2. Precaution And Notices
2.1 Assembly Precaution
(1) Please do not press or scratch LCD panel surface with anything hard. And do not soil LCD panel surface by
touching with bare hands (Polarize film, surface of LCD panel is easy to be flawed)
In the LCD panel, the gap between two glass plates is kept perfectly even to maintain display characteristic
and reliability. If this panel is subject to hard pressing, the following occurs:
(a) Uniform color
(b) Orientation of liquid crystal becomes disorder
(2) Please wipe out LCD panel surface with absorbent cotton or soft cloth in case of it being soiled.
(3) Please wipe out drops of adhesive like saliva and water in LCD panel surface immediately.
They might damage to cause panel surface variation and color change.
(4) Do not apply any strong mechanical shock to the LCD panel.
2.2 Operating Precaution
(1) Please be sure to unplug the power cord before remove the back-cover. (Be sure the power is turn-off)
(2) Please do not change variable resistance settings in MAIN-BOARD; they are adjusted to the most suitable
value. If they are changed, it might happen LUMINANCE does not satisfy the white balance spec.
(3) Please consider that LCD backlight takes longer time to become stable of radiation characteristic in low
temperature than in room temperature.
(4) Please pay attention to displaying the same pattern for very long-time. Image might stick on LCD.
2.3 Storage Precaution
(1) When you store LCD for a long time, it is recommended to keep the temperature between 0°C -40°C without
the exposure of sunlight and to keep the humidity less than 85% RH.
(2) Please do not leave the LCD in the environment of high humidity and high temperature such as 60°C,
85%RH.
(3) Please do not leave the LCD in the environment of low temperature; below -25°C.
2.4 High Voltage Warning
The high voltage was only generated by INVERTER module on Power Board, if carelessly contacted the
transformer on this module, can cause a serious shock. (The lamp voltage after stable around 600V, with lamp
current around 8mA, and the lamp starting voltage was around 1500V, at Ta=25°C)
