[. . . ] Do not cover the slots and openings on the back or top of the cabinet, as the monitor requires ventilation. The monitor should be located in a well-ventilated room to prevent the possibility of overheating. Do not allow sharp objects such as knives, pens, or pencils near the screen. If such objects touch the screen, the LCD panel may be permanently scratched. [. . . ] A soft, lint-free cloth should be used to clean the outside of the monitor. A cloth slightly moistened with a mild detergent solution will clean stubborn stains. Do not spray liquid directly on the monitor -- it is best to lightly spray on to a cloth and then gently wipe the monitor. If liquid gets inside the monitor it can cause electrical shock and/or damage to the unit. If you encounter a problem, please check the "Troubleshooting" section first. If this does not resolve the problem, do not attempt to repair the monitor by yourself. Opening or removing covers can lead to injury or death through electrocution or other hazards. Please contact a qualified engineer if the troubleshooting section does not solve your problem.
