Important Safety Information
Always be careful when using your TV. To reduce the risk of fire, electrical shock, and other injuries,
keep these safety precautions in mind when installing, using, and maintaining your unit.
•Read all safety and operating instructions before operating your TV.
•Keep the safety and operating instructions for future reference.
•Heed all warnings on the TV and in the operating instructions.
•Unplug the TV from the wall outlet before cleaning. Use a damp cloth; do not use liquid or
aerosol cleaners.
•Never add any attachments and/or equipment without approval of the manufacturer. Such
additions can increase the risk of fire, electric shock, or other personal injury.
•Do not use the TV where contact with water is possible, such as near bath tubs, sinks, washing
machines, swimming pools, etc.
•Do not place the TV on an unstable cart, stand, tripod, bracket, or table where
it can fall. A falling TV can cause serious injury to a child or adult, and serious
damage to the appliance. Use only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer or sold with the TV. Follow the
manufacturer’s instructions when mounting the unit, and use a mounting
accessory recommended by the manufacturer. Move the TV and cart with care.
Quick stops, excessive force, and uneven surfaces can make the unit and cart
unsteady and more likely to overturn.
•The TV is designed with slots in the cabinet for ventilation to protect it from overheating. Do not block
these openings with any object, and do not put the TV on a bed, sofa, rug, or other similar surface. Do
not put the TV near a radiator or heat register. If you do put the TV on a rack or
bookcase, make sure that there is adequate ventilation and that you’ve followed the manufacturer’s
instructions for mounting.
•Operate your TV only from the type of power source indicated on the marking label. If you are not sure
of the type of power supplied to your home, consult your appliance dealer or local power company.
•Use only a grounded or polarized outlet. For your safety, this TV is equipped with a polarized alternat-
ing current line plug having one blade wider than the other. This plug will fit into the power outlet only
one way. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug still
does not fit, contact an electrician to replace your outlet.

SAMS
Safety Instructions

•Protect the power cord. Power supply cords should be routed so that they won’t be walked on or
pinched by objects placed on or against them. Pay particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the unit.
•Unplug the TV from the wall outlet and disconnect the antenna or cable system during a lightning storm
or when left unattended and unused for long periods of time. This will prevent damage to the unit from
lightning and power-line surges.
•Avoid overhead power lines. An outside antenna system should not be placed in the vicinity of over-
head power lines or other electric light or power circuits, or where it can fall into such power lines or
circuits. When installing an outside antenna system, be extremely careful to keep from touching the
power lines or circuits. Contact with such lines can be fatal.
•Do not overload the wall outlet or extension cords. Overloading can result in fire or electric shock.
•Do not insert anything through the openings in the unit, where they can touch dangerous voltage points
or damage parts. Never spill liquid of any kind on the TV.
•Ground outdoor antennas. If an outside antenna or cable
system is connected to the TV, be sure the antenna or cable
system is grounded so as to provide some protection against
voltage surges and built-up static charges. Section 810 of the
National Electrical Code, ANSI/NFPA No.70-1984, pro-
vides information about proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conductors,
location of antenna discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.
•Do not attempt to service the TV yourself. Refer all servicing to qualified service personnel. Unplug the
unit from the wall outlet and refer servicing to qualified service personnel when:
- The power-supply cord or plug is damaged
- Liquid has been spilled on the unit or if objects have fallen into the unit
- The TV has been exposed to rain or water
- The TV does not operate normally by following the operating instructions
- The TV has been dropped or the cabinet has been damaged
- The TV exhibits a distinct degradation in performance
- When the LAMP(BULB ONLY) replacement is needed
•If you make adjustments yourself, adjust only those controls that are covered by the operating instruc-
tions. Adjusting other controls may result in damage and will often require extensive work by a qualified
technician to restore the TV to normal.
•When replacement parts are required, be sure the service technician uses replacement parts specified
by the manufacturer or those that have the same characteristics as the original part. Unauthorized
substitutions may result in additional damage to the unit.
•Upon completion of any service or repairs to this TV, ask the service technician to
perform safety checks to determine that the TV is in a safe operating condition.
