Important safeguards
Warning Risk of electric shock - Do not open
To reduce the risk of electric shock, do not remove the back
cover. There are no user-serviceable parts inside.
Removing the back cover voids the warranty.
Have your LCD TV repaired by qualified service personnel
only.
Warnings and precautions
■ Do not place your hands, face, or objects close to the ventilation openings
of your LCD TV. The top of your LCD TV gets very hot from exhaust air
that is released through the ventilation openings. Burns or personal
injuries may occur if you are too close to the LCD TV. Damage may occur
if you place any object near the top of your LCD TV.
■ Disconnect all cables before moving your LCD TV. Moving your LCD TV
with its cables attached may damage the cables and cause fire or electric
shock danger.
■ Do not expose your LCD TV to rain or moisture.
Important safeguards
■ Keep your LCD TV away from excessive dust, high temperatures, moisture,
or direct sunlight.
■ Use your LCD TV in a well-ventilated area and do not cover the ventilation
openings.
■ Do not modify your LCD TV or use an unshielded power cord or video
input source cable, or you may experience excessive interference.
■ Disconnect your LCD TV and unplug the power cord when the TV is not
used for a long period of time.
■ If the picture displayed is in any way abnormal, turn off your LCD TV, then
disconnect it from the electrical outlet. Make sure that your video input
source cable is connected correctly, then reconnect your LCD TV to the
electrical outlet.
■ Disconnect your LCD TV from the electrical outlet before cleaning or
performing maintenance. Do not use liquid or aerosol cleaners. Use only
a slightly damp cloth for cleaning.
■ Do not place your LCD TV on an unstable cart, stand, or table. Your
LCD TV may fall, causing serious damage.

Chapter 1: Introducing Your Gateway LCD TV
■ Do not place your LCD TV on a bed, sofa, rug, or other similar surfaces.
■ Never place your LCD TV near or over a radiator or heat source.
■ Do not install your LCD TV in an enclosed area unless correct ventilation
is provided.
■ Your LCD TV should be operated from the type of power source indicated
on the label. If the type of available power is unknown, consult your
electrician or local power company.
■ Your LCD TV is equipped with a 3-pin grounded plug. The plug will only
fit into a grounded power outlet. This is a safety feature. If you cannot
plug the power cord into the outlet, contact your electrician. Do not alter
the plug because this will defeat the safety feature.
■ Do not rest objects on the power cord and avoid placing the power cord
near high traffic areas.
■ Do not overload wall outlets and extension cords because this can result
in a risk of fire or electric shock.
■ Unplug your LCD TV and contact qualified service personnel if:
■ The power cord or plug is damaged or frayed.
■ Liquid has been spilled into your LCD TV.
■ Your LCD TV has been exposed to water or moisture.
■ Your LCD TV does not operate normally when the operating
instructions are followed. Adjust only those controls that are covered
by the operating instructions. Incorrect adjustment of other controls
may result in damage which often requires extensive work by a
qualified technician to restore your LCD TV to normal operation.
■ Your LCD TV has been dropped or the cabinet has been damaged.
