BEFORE OPERATION (continued)

Precautions

Power Sources-The TV set should be operated only from the type of power source indicated on the TV set or as indicated in
the Operation Manual. If you are not sure of the type of power supply in your home,consult your sales person or your local
power company. For TV sets designed to operate from battery power, or other sources, refer to the operating instructions.

Grounding or Polarization-Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the
third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of
the obsolete outlet.

Alternate Warnings-This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to
insert the plug into the outlet, contact your electrician to have a suitable outlet installed. Do not defeat the safety purpose of
the grounding plug.

Water and Moisture Warnings-Do not use the TV set near water-for example, near a bath tub, wash bowl, kitchen sink, or
laundry tub; in a wet basement; or near a swimming pool; and the like. The TV set shall not be exposed to dripping or
splashing and no objects filled with liquids, such as vases, shall be placed on the TV set.

Ventilation-Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the TV set and to
protect it from overheating, and these openings must not be blocked or covered. The openings should never be blocked by
placing the TV set on a bed, sofa, rug, or other similar surface. This TV set should not be placed in a built-in installation such
as a bookcase or rack unless proper ventilation is provided or the manufacturer's instructions have been adhered to.

Heat-Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers)
that produce heat.

Power-Cord Protection-Protect the power cord from being walked on or pinched particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.

Accessories-Do not place the TV set on an unstable cart, stand, tripod, bracket, or table. The TV set may fall, causing serious
injury to a child or adult, and serious damage to the TV set. Use only with a cart, stand, tripod, bracket, or table recommended
by the manufacturer, or accessory recommended by the manufacturer, or sold with the TV set and should use a mounting
accessory recommended by the manufacturer.

A product and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the
TV set and cart combination to overturn.

Overloading-Do not overload wall outlets, extension cords or integral convenience receptacles as this can result in fire or
electric shock.

Lightning-For added protection for this TV set during a lightning storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the
product due to lightning and power-line surges.

Object and Liquid Entry-Never push objects of any kind into the TV set through openings as they may touch dangerous
voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind on the TV set.

b. If liquid has been spilled or objects have fallen into the TV set.
c. If the TV set has been exposed to rain or water.
d. If the TV set has been subject to excessive shock by being dropped, or the cabinet has been damaged.
e. If the TV set does not operate normally by following the operating instructions. Adjust only those controls that are covered

by the operating instructions as an improper adjustment of other controls may result in damage and will often require
extensive work by a qualified technician to restore the TV set to its normal operation.

f. When the TV set exhibits a distinct change in performance-this indicates a need for service.

Servicing-Do not attempt to service the TV set yourself as opening or removing covers may expose you to dangerous voltage
or other hazards. Refer all servicing to qualified service personnel.

Replacement Parts-When replacement parts are required, be sure the service technician has used replacement parts
specified by the manufacturer or have the same characteristics as the original parts. Unauthorized substitutions may result in
fire, electric shock, or other hazards.

Safety Check-Upon completion of any service or repairs to the TV set, ask the service technician to perform routine safety
checks to determine that the TV set is in proper operating condition.

When the TV set reaches the end of its useful life, improper disposal could result in a picture tube implosion. Ask a qualified
service technician to dispose of the TV set.

ANTENNA

Outdoor Antenna Grounding-if an outdoor antenna is installed, follow the precautions below.
An outdoor antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits,
or where it can come in contact with such power lines or circuits.
WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM, EXTREME CARE SHOULD BE TAKEN TO KEEP FROM
CONTACTING SUCH POWER LINES OR CIRCUITS AS CONTACT WITH THEM IS ALMOST INVARIABLY FATAL
