Please read this entire manual before using this device, paying extra
attention to these safety warnings and guidelines. Please keep this
manual in a safe place for future reference.
•This device is intended for indoor use only.
•Do not expose this device to water or moisture of any kind. Do
not place drinks or other containers with moisture on or near the
device. If moisture does get in or on the device, immediately
remove it from its power source and allow it to fully dry before
reapplying power.
•Do not touch the device, the power cord, or any other connected
cables with wet hands.
•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 subject the product to extreme force, shock, or
fluctuations in temperature or humidity.
•Do not expose this device to excessively high temperatures. Do
not place it in, on, or near a heat source, such as a fireplace,
stove, radiator, etc. Do not leave it in direct sunlight.
•This device ventilates excessive heat through the slots and
openings in the case. Do not block or cover these openings.
Ensure that the device is in an open area where it can get
sufficient airflow to keep from overheating.
•Do not place or install this device in an area where it can be
exposed to excessive amounts of dust, humidity, oil, smoke, or
combustible vapors.

•Prior to operation, check the unit and power cord for physical
damage. Do not use if physical damage has occurred.
•Before plugging the unit into a power outlet, ensure that the
outlet provides the same type and level of power required by the
device.
•Unplug this device from the power source when not in use.
•Take care to prevent damage to the power cord. Do not allow it
to become crimped, pinched, walked on, or become tangled with
other cords. Ensure that the power cord does not present a
tripping hazard.
•Never unplug the unit by pulling on the power cord. Always
grasp the connector head or adapter body.
•Clean using a soft, dry cloth only. Do not use chemical cleaners,
solvents, or detergents. For stubborn deposits, moisten the cloth
with warm water.
•This monitor has no user serviceable parts. Do not open the case
or otherwise attempt to modify this monitor.
•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.
