FCC Class B Radio Frequency Interference Statement
WARNING: (FOR FCC CERTIFIED MODELS)
NOTE: This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate
radio frequency energy, and if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
4. Consult the dealer or an experienced radio/TV technician for help.
NOTICE:
1. The changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the
equipment.
2. Shielded interface cables and AC power cord, if any, must be used in
order to comply with the emission limits.
3. The manufacturer is not responsible for any radio or TV interference
caused by unauthorized modification to this equipment. It is the
responsibilities of the user to correct such interference.

PRECAUTIONS
z Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen
sink, laundry tub, swimming pool or in a wet basement.
z Do not place the monitor on an unstable cart, stand, or table. If the monitor
falls, it can injure a person and cause serious damage to the appliance.
Use only a cart or stand recommended by the manufacturer or sold with
the monitor. If you mount the monitor on a wall or shelf, use a mounting kit
approved by the manufacturer and follow the kit instructions.
z Slots and openings in the back and bottom of the cabinet are provided for
ventilation. To ensure reliable operation of the monitor and to protect it
from overheating, be sure these openings are not blocked or covered. Do
not place the monitor on a bed, sofa, rug, or similar surface. Do not place
the monitor near or over a radiator or heat register. Do not place the
monitor in a bookcase or cabinet unless proper ventilation is provided.
z 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.
z 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 ground the appliance safely.
Do not defeat the safety purpose of the grounded plug.
z Unplug the unit during a lightening storm or when it will not be used for
long period of time. This will protect the monitor from damage due to
power surges.
z Do not overload power strips and extension cords. Overloading can result
in fire or electric shock.
z Never push any object into the slot on the monitor cabinet. It could short
circuit parts causing a fire or electric shock. Never spill liquids on the
monitor.
z Do not attempt to service the monitor by yourself; opening or removing
covers can expose you to dangerous voltages and other hazards. Please
refer all servicing to qualified service personnel.
z To ensure satisfactory operation, use the monitor only with UL listed
computers which have appropriate configured receptacles marked
between 100 - 240V AC, Min. 5A.
z The wall socket shall be installed near the equipment and shall be easily
accessible.
