Precautions
Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub, swimming pool or in a
wet basement.
Do not place the monitor on an unstable trolley, stand, or table. If the monitor falls, it can injure a person and cause
serious damage to the appliance. Use only a trolley 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.
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.
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.
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.
Do not attempt to service the monitor yourself; opening or removing covers can expose you to dangerous voltages and
other hazards. Please refer all servicing to qualified service personnel
To ensure satisfactory operation, use the monitor only with UL listed computers which have appropriate configured
receptacles marked between 100-240V AC, Min. 3.5A.
The wall socket shall be installed near the equipment and shall be easily accessible.
For use only with the attached power adapter (output 12V DC), which has UL, CSA listed license
