Precautions

• The monitor may be damaged if placed too near a source of heat. Be aware of the location of radiators, cookers, open fires etc.
• 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 will be permanently scratched.
• When cleaning this monitor, disconnect it from the electric socket to avoid any danger of electrocution. A soft, lint-free cloth should be used to clean the outside of the monitor. A cloth very slightly moistened with a mild detergent solution will clean stubborn stains. Keep liquids away from the display screen, including sprays. Do not spray liquid directly - it is best to lightly spray on to a cloth and wipe. 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 among other hazards. Please contact a qualified engineer if you find the troubleshooting section does not help.
