Safety
National Conventions
The following subsections describe national conventions used in this document.
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: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to
avoid the problem.
WARNING: A WARNING indicates the potential for bodily harm and tells you how to avoid the problem.
Some warnings may appear in alternate formats and may be unaccompanied by an icon. In such cases,
the specic presentation of the warning is mandated by regulatory authority.

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 t 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 re or electric shock.
To ensure satisfactory operation, use the monitor only with UL listed computers which have
appropriate congured receptacles marked between 100-240V AC, Min. 5A.
The wall socket shall be installed near the equipment and shall be easily accessible.

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. A product
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
re or electric shock. Never spill liquids on the monitor.
Do not place the front of the product on the oor.
If you mount the monitor on a wall or shelf, use a mounting kit approved by the manufacturer and
follow the kit instructions.
Leave some space around the monitor as shown below. Otherwise, air-circulation may be inadequate
hence overheating may cause a re or damage to the monitor.
To avoid potential damage, for example the panel peeling from the bezel, ensure that the monitor
does not tilt downward by more than -5 degrees. If the -5 degree downward tilt angle maximum is
exceeded, the monitor damage will not be covered under warranty.
