Observe the folowing safety guidelines when connection and using your monitor:
·Be sure that your monitor is electrically rated to operate with the AC power available inyour location.
·Locate your monitor near an easily accessible electrical outlet.
·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.
·Put your monitor in a location with low humidity and a minimum of dust.
·Never use your monitor if the power cable has been damaged. Do not allow anything to rest on the power cable, and keep
the cable away from where people could trip over it.
·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.
·Be sure to hold the plug, not the cable, when disconnecting the monitor from an electrical outlet.
·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.

•placing your display in such a way that the side faces the window or any light
source
•minimizing room light by using drapes, shades or blinds
•using a task light
•changing the display’s viewing angle
•using a glare-reduction filter
•using a display visor, such as a piece of cardboard extended from the display’s
top front edge
•Avoid adjusting your display to an awkward viewing angle.
•Avoid looking at bright light sources, such as open windows, for extended
periods of time.
