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:

CAUTION: A CAUTION 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.
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.

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, 3G, 0.75 mm2, or better. For
other countries, the suitable types shall be used accordingly.
IExcessive 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.
