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 of input voltages, from 100 to
240 VAC, 50 or 60 Hz, with a current of at least 1.7A. 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
powered off for at least 2 hours out of every 12.
