IMPORTANT SAFEGUARDS
For your protection, please read these instructions 
completely, and keep this manual for future reference. 
Carefully observe and comply with all warnings, cautions 
and instructions placed on the set, or described in the 
operating instructions or service manual.
WARNING
To guard against injury, the following basic safety 
precautions should be observed in the installation, use, and 
servicing of the set.
Use
Power Sources
This set should be operated only from 
the type of power source indicated on 
the serial/model plate. If you are not 
sure of the type of electrical power 
supplied to your home, consult your 
dealer or local power company. For 
those sets designed to operate from 
battery power, refer to the operating instructions.
Grounding or Polarization
This set may be equipped with a polarized alternating current 
line plug (a plug having one blade wider than other). This 
plug will fit into the power outlet only one way. This is a safety 
feature. If you are unable to insert the plug fully into the 
outlet, try reversing the plug. If the plug still fails to fit, contact 
your electrician to replace your obsolete outlet. Do not defeat 
the safety purpose of the polarized plug.
For the set with a polarized AC power cord plug
This plug will fit into the power outlet 
only one way. This is a safety feature. 
If you are unable to insert the plug 
fully into the outlet, try reversing the 
plug. If the plug still fails to fit, contact 
your electrician to have a suitable outlet installed. Do not 
defeat the safety purpose of the polarized plug by forcing it in.
Alternate Warning
For the set with a three-wire grounding type AC plug
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.
Overloading
Do not overload wall 
outlets, extension 
cords or convenience 
receptacles beyond 
their capacity, since 
this can result in fire 
or electric shock. 
Always turn the set off when it is not to be used. When the 
set is left unattended and unused for long periods of time, 
unplug it from the wall outlet as a precaution against the 
possibility of an internal malfunction that could create a fire 
hazard.
Do not disconnect the antenna or the power cord during a 
heavy storm. Lightning may strike while you are holding 
the cable or cord, causing serious injury. Turn off your TV 
and wait for the weather to improve.
Object and Liquid Entry
Never push objects of any kind into the set 
through the cabinet slots 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 set.
Attachments
Do not use attachments not recommended 
by the manufacturer, as they may cause 
hazards.
Do not place any objects, especially heavy 
objects, on top of the set. The object may 
fall from the set, causing injury.
Cleaning
Unplug the set from the wall outlet before 
cleaning or polishing it. Do not use liquid 
cleaners or aerosol cleaners. Use a cloth 
lightly dampened with water for cleaning 
the exterior of the set.
If a snapping or popping sound from a TV set 
is continuous or frequent while the TV is 
operating, unplug the TV and consult your 
dealer or service technician. It is normal for 
some TV sets to make occasional snapping or 
popping sounds, particularly when being 
turned on or off.
Installation
Always use two or more people to lift or move the set. The 
set is heavy and the bottom surface is flat. Serious injury can 
result from trying to move the set by yourself alone, or from 
unsteady handling. 
Install the set on a stable, level surface.
Water and Moisture
Do not use power-line 
operated sets near water — 
for example, near a bathtub, 
washbowl, kitchen sink, or 
laundry tub, in a wet 
basement, or near a 
swimming pool, etc.
Accessories
Do not place the set on 
an unstable cart, stand, 
tripod, bracket, table, 
or shelf. The set may 
fall, causing serious 
injury to a child or an 
adult, and serious 
damage to the set. Use 
only a cart or stand recommended by the manufacturer for the 
specific model of TV. Any mounting of the product should 
follow the manufacturer’s instructions, and should use a 
mounting accessory recommended by the manufacturer. An 
appliance and cart combination should be moved with care. 
Quick stops, excessive force, and uneven surfaces may cause 
the appliance and cart combination to overturn.
Ventilation
The slots and openings in the cabinet and in the back or 
bottom are provided for necessary ventilation. To ensure 
reliable operation of the set, and to protect it from 
overheating, these slots and openings must never be 
blocked or covered.
01US01COV-BR2.book  Page 4  Tuesday, May 20, 2003  3:37 PM 
						

							 Connecting Additional Equipment
Never cover the slots and openings 
with a cloth or other materials.

Never block the slots and openings 
by placing the set on a bed, sofa, rug 
or other similar surface.
Never place the set in a confined 
space, such as a bookcase or built-in 
cabinet, unless proper ventilation is 
provided.
Do not place the set near or over a 
radiator or heat register, or where it is 
exposed to direct sunlight.
Power-Cord Protection
Do not allow anything to rest on or roll over the 
power cord, and do not place the set where the 
power cord is subject to wear or abuse.
Antennas
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.
Be sure the antenna system is grounded so as to provide some 
protection against voltage surges and built-up static charges. 
Section 810 of the National Electrical Code (NEC) in USA and 
Section 54 of the Canadian Electrical Code in Canada 
provides information with respect to 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.
Antenna Grounding According to the NEC
Antenna Grounding According to the National Electrical 
Code, ANSI/NFPA 70.
Lightning
For added protection for this television receiver 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. This will prevent damage to the 
receiver due to lightning and power-line surges.
Service
Damage Requiring Service
Unplug the set from the wall outlet and refer servicing to 
qualified service personnel under the following conditions:

When the power cord or plug 
is damaged or frayed.
If liquid has been spilled 
into the set or objects have 
fallen into the product.
If the set has been exposed to 
rain or water.
If the set has been subject to 
excessive shock by being 
dropped, or the cabinet has 
been damaged.

If the set does not operate 
normally when following the operating 
instructions. Adjust only those controls 
that are specified in the operating 
instructions. Improper adjustment of 
other controls may result in damage and 
will often require extensive work by a 
qualified technician to restore the set to normal operation.
When the set exhibits a distinct change in 
performance — this indicates a need for service.
Servicing
Do not attempt to service the set yourself 
since opening the cabinet 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 certifies in 
writing that he has used replacement 
parts specified by the manufacturer that 
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 set, ask the service technician to perform 
routine safety checks (as specified by the 
manufacturer) to determine that the set is in 
safe operating condition, and to so certify. 
When the 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 set.GROUND
