Caution: Use of controls, adjustments, or procedures other than those specified in this
document may result in exposure to shock, electrical hazards, and/ or mechanical
hazard.
Read and follow these instructions when connecting and using the LCD monitor:
To help avoid damaging your computer, be sure that the voltage selection switch on
the power supply for the computer is set to match the alternating current (AC) power
available at your location:
§ 110 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries
such as Japan (100 volts), South Korea (220 volts (V)/60 hertz (Hz)), and Taiwan.
§ 230 volts (V)/50 hertz (Hz) in most of Europe, the Middle East, and the Far East.
§ Always be sure that you are operating within the valid electrical rating in your location
§ Never insert anything metallic into the LCD monitor openings. Doing so may create the danger
of electric shock
§ Never touch the inside of the LCD monitor. Only a qualified technician should open the case.
§ Never use the LCD monitor if the power cable has been damaged. Do not allow anything to rest
on the power cable.
§ Keep the power cable away from where people could trip over it.
§ Be sure to grasp the plug, not the cable, when disconnecting the LCD monitor from an electric
socket.
§ Do not remove the ground pin. By doing so, you will defeat the safety. A polarized plug has two
blades wider than the other. A grounding type plug has two blades and third grounding prong.
The wide blade or third prong is provided for your safety.
§ When the provided plug does not fit into your electrical outlet, consult an electrician for the
replacement of the plug.
§ To prevent overheating, do not block or covered openings of the LCD monitor.
§ Avoid using the LCD Monitor on a bed, sofa, rug, or other soft surface, as doing so may block
ventilation openings in the bottom of the cabinet. If you place the LCD monitor in a bookcase or
an enclosed space, make sure to provide adequate ventilation and air flow.
§ Place the LCD monitor in a location with low humidity and minimum dust.
§ Avoid places such as a damp base and a dusty hallway.
§ Do not expose the LCD monitor to rain or use it near water (in kitchens, next to swimming pools,
etc.). If the LCD monitor accidentally gets wet, unplug it and contact your dealer immediately.
You can clean the LCD monitor with a damp cloth if necessary, being sure to unplug the LCD
monitor first.
§ Place the LCD monitor on a solid surface and treat it carefully. The LCD monitor is fragile and
cannot be damaged, dropped or hit sharply. When use with a cart, stand, tripod, bracket, or table,
being sure that the LCD monitor is adequately supported.
§ Unplug the LCD monitor during lightning storms or when unused for long periods of time.
§ Locate the LCD monitor near an easily accessible electric outlet.
§ If the LCD monitor does not operate normally - in particular, if there are any unusual sounds or
smells arising from the LCD monitor unplug it immediately and contact your local dealer.
