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
