Safety
National Conventions
The following subsections describe notational 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 specic presentation of the
warning is mandated by regulatory authority.

2
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 congured
receptacles marked between 100-240V AC, Min. 5A.
The wall socket shall be installed near the equipment and shall be easily accessible.

3
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.
See below the recommended ventilation areas around the monitor when the monitor is installed on the wall or on the
stand:
Installed with stand
12 inches
30cm
4 inches
10cm
4 inches
10cm
4 inches
10cm
Leave at least this much
space around the set

Cleaning
Clean the cabinet regularly with a water-dampened, soft cloth.
When cleaning use a soft cotton or microber cloth. The cloth should be damp and almost dry, do not allow liquid
into the case.
Please disconnect the power cord before cleaning the product.

5
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.
Do not knock or drop the monitor during operation or transportation.
The power cords shall be safety approved. For Germany, it shall be H03VV-F/H05VV-F, 3G, 0.75 mm2, or better.
For other countries, the suitable types shall be used accordingly.
Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the equalizer to
maximum increases the earphones and headphones output voltage and therefore the sound pressure level.
