5Precautions for useThe liquid crystal parts are fabricated using high-precision technology. The screen has effective pixelsthat cover more than 99.99% of its area, but pixels may be missing or remain permanently lighted (red,blue and/or green) in less than 0.01% of the area. This is not indicative of malfunctioning.The panel which protects the liquid crystal display has been specially treated.Do not wipe it with hard cloths or rub it heavily as this will damage the surface of the panel.If a still image is displayed continuously for a long period of time, the image may be burnt onto thescreen for some time.(The shadow of the image will usually disappear after moving images are displayed for while.)The response speed and brightness of the liquid crystals will vary with the surrounding temperature.Do not expose the liquid crystal display to strong light, as it could cause a deterioration in the displaycharacteristics and reduce the display quality.Do not keep in an environment where the temperature changes suddenly, because condensation couldform on the surface of the liquid crystal or in the internal parts and cause a reduction in the displayquality or a malfunction.Screen irregularities may be generated when certain images are displayed.If the unit is left for a long time in a location with a high temperature or humidity, it could change thecharacteristics of the liquid crystal panel and cause irregularities.This product has been specially designed for commercial use. As such, it should be used and operatedonly by persons with related expertise.
