Safety Warnings and Guidelines
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 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 this device to excessive vibration or 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 it 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.

3
•This device uses a grounded power cord and requires a ground
connection for safe operation. Ensure that the power source has a
proper ground connection. Do not modify the plug or use a
"cheater" plug to bypass the ground connection.
•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.
•Ensure that power is turned off and disconnected before making
any electrical connections.
•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 device has no user-serviceable parts. Do not attempt to open,
service, or modify this device.
•Do not leave a single image on the display for a long period of time.
Doing so could cause a "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.
•Keep the original foam packaging material for use when installing or
removing the included stand.
