Please be sure to unplug the power cord before remove the back-cover. (be sure the power is turn-off)
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.
Please consider that LCD backlight takes longer time to become stable of radiation characteristic in low temperature
than in room temperature.
Please pay attention to displaying the same pattern for very long-time. Image might stick on LCD.
2-3 STORAGE PRECAUTION
When you store LCD for a long time, it is recommended to keep the temperature between 0°C -40°C without the

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)
