Safety Instructions

Please read and follow these instructions when connecting and using your computer monitor:
S Never insert anything metallic into the monitor openings. Doing so may create the danger of electric shock.
S To avoid electric shock, never touch the inside of the monitor. Only a qualified technician should open the monitor's case
S 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.
S Be sure to hold the plug, not the cord, when disconnecting the monitor from an electric socket.
S 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 block 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.
S Put your monitor in a location with low humidity and a minimum of dust. Avoid places like damp basements or dusty hallways.
S 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, un-
plug 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.
S Place the monitor on a solid surface and treat it carefully. The screen can be damaged if dropped, sharply hit or touched with a sharp or
abrasive implement.
S Locate your monitor near an easily accessible AC outlet.
S 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.
