SAFETY WARNINGS AND GUIDELINES
•Do not place the monitor on an unstable surface where it could fall and cause either
personal injury or damage to the monitor and/or other equipment.
•Do not expose the monitor to water or moisture of any kind. Do not place objects
containing moisture, such as a glass or vase, where it could tip over and spill into or
onto the monitor.
•If the monitor is exposed to water or moisture, immediately unplug it from its power
source and allow it to completely dry out before reapplying power.
•Do not block the ventilation holes in the monitor's casing. Do not place the monitor in a
confined space with inadequate ventilation.
•Do not place the monitor near a heat source, such as a fireplace, heating vent, radiator,
etc.
•The power supply for this monitor uses a NEMA 5-15 three prong, grounded plug. Do
not use a "cheater" plug or otherwise bypass the grounding pin.
•The power supply for this monitor accepts a wide range input voltages, from 100 to 240
VAC, 50 or 60 Hz, with a current at least 1.75A. Ensure that your power source is within
these limits. If not, consult a professional electrician or your power company for a
resolution.
•Unplug the monitor if it will go unused for a long period of time.
•This monitor has no user serviceable parts. Do not open the case or otherwise attempt
to modify this monitor.
•Clean only using a soft, dry cloth. Do not use chemical cleaners, solvents, or
detergents. For stubborn deposits, moisten the cloth with warm water.
•Do not leave a single image on the display for a long period of time. Doing so could
cause "burn-in" of the image. It is recommended to use a variable desktop background
and to use a screen saver to prevent "burn-in". Alternatively, ensure that the monitor is
power off for at least 2 hours out of every 12.
