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 specific 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 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.
To ensure satisfactory operation, use the monitor
only with UL listed computers which have appropriate configured 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 fire or electric shock. Never
spill liquids on the monitor.
Do not place the front of the product on the floor.
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 fire 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
Cleaning
Clean the cabinet regularly with a water-dampened, soft cloth.
When cleaning use a soft cotton or microfiber 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.
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.
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.
