Notes, Cautions, and Warnings
Throughout this guide, blocks of text may be accompanied by an icon and printed in bold type or in italic type.
These blocks are notes, cautions, and warnings, and they are used as follows:
NOTE: A NOTE indicates important information that helps you make better use of your computer system.
CAUTION: ACAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.

Power
The monitor should be operated only from the type of power source indicated on the label. If you are not sure
of the type of power supplied to your home, consult your dealer or local power company.
The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin. This plug will
fit only into a grounded power outlet as a safety feature. If your outlet does not accommodate the three-wire plug,
have an electrician install the correct outlet, or use an adapter to ground the appliance safely. Do not defeat the
safety purpose of the grounded plug.
Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will protect the
monitor from damage due to power surges.
Do not overload power strips and extension cords. Overloading can result in fire or electric shock.
The wall socket shall be installed near the equipment and shall be easily accessible.

5
Installation
Do not place the monitor on an unstable cart, stand, tripod, bracket, or table. If the monitor falls, it can injure a
person and cause serious damage to this product. Use only a cart, stand, tripod, bracket, or table recommended by
the manufacturer or sold with this product. Follow the manufacturer’s instructions when installing the product and
use mounting accessories recommended by the manufacturer. Aproduct and cart combination should be moved
with care.
Never push any object into the slot on the monitor cabinet. It could damage circuit parts causing a fire or
electric shock. Never spill liquids on the monitor.
Do not place the front of the product on the floor.
Leave some space around the monitor as shown below. Otherwise, air-circulation may be inadequate hence
overheating may cause a fire or damage to the monitor.
See below the recommended ventilation areas around the monitor when the monitor is installed with the stand:

6
Cleaning
Clean the cabinet regularly with cloth. You can use soft-detergent to wipe out the stain, instead of
strong-detergent which will cauterize the product cabinet.
When cleaning, make sure no detergent is leaked into the product. The cleaning cloth should not be too rough
as it will scratch the screen surface.
Please disconnect the power cord before cleaning the product.

7
Other
If the product is emitting a strange smell, sound or smoke, disconnect the power plug IMMEDIATELY and
contact a Service Center.
Make sure that the ventilating openings are not blocked by a table or curtain.
Do not engage the LCD monitor in severe vibration or high impact conditions during operation.
