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.
