PRECAUTIONS
zThe monitor may be damaged if placed too near a source of heat.
Be aware of the location of radiators, cookers, open fires etc.
zDo 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.
zDo 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.
zWhen 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.
zIf 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.

CARING FOR YOUR LCD MONITOR
zFirst, unplug the power cord from the wall socket
zIf the LCD screen is extremely dirty, clean it with a moist cloth. Use only warm
water and then wipe the monitor dry. Solvents or harsh cleaners can damage the
housing. Clean the display surface only with a soft cloth, otherwise you may
damage the display’s coating
zIf the monitor is only slightly dirty, clean it using a soft, dry and antistatic
cloth.
zThe LCD monitor’s screen surface is very sensitive. Please avoid any
contact with the surface (finger, pencil, etc.) and be especially
cautious during transportation since jolts and shocks can cause the
screen to become scratched (always use the original packaging).
