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).

Carefully lift the monitor out of the packaging and make sure that all components are
