Safety InstructionsSafety Instructions
Please read and follow these instructions when connecting and using your computer monitor:
To help avoid damaging your computer, be sure the voltage selection switch on the power supply is set to
match the alternating current (AC) power available at your location:
• 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as
Japan, South Korea, and Taiwan.
• 230 V/50 Hz in most of Europe, the Middle East, and the Far East. Also be sure your monitor is electrically
rated to operate with the AC power available in your location.
Never insert anything metallic into the monitor openings. Doing so may create the danger of electric shock.
To avoid electric shock, never touch the inside of the monitor. Only a qualified technician should open the
monitor's case.
Never use your monitor if the power cord has been damaged. Do not allow anything to rest on the power
cord, and keep the cord away from where people could trip over it.
Be sure to hold the plug, not the cord, when disconnecting the monitor from an electric socket.
Openings in the monitor cabinet are provided for ventilation. To prevent overheating, these openings should
not be blocked or covered. Also, avoid using the monitor on a bed, sofa, rug, or other soft surface. Doing so
may bolck the ventilation openings in the bottom of the cabinet. If you put the monitor in a bookcase or some
other enclosed space, be sure to provide adequate ventilation.
Put your monitor in a location with low humidity and a minimum of dust. Avoid places like damp basement or
dusty hallways.
Do not expose the monitor to rain or use it near water (in kitchens, next to swimming pools, etc.). If the
monitor accidentally gets wet, unplug it and contact an authorized dealer immediately. You can clean the
monitor with a damp cloth when necessary, but be sure to unplug the monitor first.
Place the monitor on a solid surface and treat it carefully. The screen is made of glass and can be damaged if
dropped or sharply hit.
Locate your monitor near an easily accessible AC outlet.
If your monitor does not operate normally - in particular, if there are any unusual sounds or smells coming
from it - unplug it immediately and contact an authorized dealer or service center.
