yyProtect the power cord from being walked on
or pinched particularly at plugs, convenience
receptacles, and the point where they exit
from the apparatus.
yy
CAUTION concerning the Power Cord
(Can differ by country):
It is recommended that appliances be
placed upon a dedicated circuit; that is, a
single outlet circuit which powers only that
appliance and has no additional outlets or
branch circuits. Check the specification page
of this owner’s manual to be certain. Do not
connect too many appliances to the same
AC power outlet as this could result in fire or
electric shock. Do not overload wall outlets.
Overloaded wall outlets, loose or damaged
wall outlets, extension cords, frayed power
cords, or damaged or cracked wire insulation
are dangerous. Any of these conditions could
result in electric shock or fire. Periodically
examine the cord of your appliance, and if its
appearance indicates damage or deterioration,
unplug it, discontinue use of the appliance,
and have the cord replaced with an exact
replacement part by an authorized service.
Protect the power cord from physical or
mechanical abuse, such as being twisted,
kinked, pinched, closed in a door, or walked
upon. Pay particular attention to plugs, wall
outlets, and the point where the cord exits
the appliance. Do not move the TV with the
yyOnly use attachments/accessories specified
by the manufacturer.
yyUse only with a cart, stand, tripod, bracket,
or table specified by the manufacturer, or
sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus
combination to avoid injury from tip-over.

or when unused for long periods of time.
power cord plugged in. Do not use a damaged
or loose power cord. Be sure do grasp the
plug when unplugging the power cord. Do not
pull on the power cord to unplug the TV.
yyRefer all servicing to qualified service
personnel. Servicing is required when the
apparatus has been damaged in any way, such
as power-supply cord or plug is damaged,
liquid has been spilled or objects have fallen
into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate
normally, or has been dropped.
yy

yyGrounding
yyCleaning
When cleaning, unplug the power cord and
wipe gently with a soft cloth to prevent
scratching. Do not spray water or other liquids
directly on the TV as electric shock may occur.
Do not clean with chemicals such as alcohol,
thinners or benzine.
(Except for devices which are not grounded.)
Ensure that you connect the earth ground
wire to prevent possible electric shock (i.e. a
TV with a three-prong grounded AC plug must
be connected to a three-prong grounded AC
outlet). If grounding methods are not possible,
have a qualified electrician install a separate
circuit breaker. Do not try to ground the unit
by connecting it to telephone wires, lightening
rods, or gas pipes.
yyMoving
Make sure the product is turned off,
unplugged and all cables have been removed.
It may take 2 or more people to carry larger
TVs. Do not press or put stress on the front
panel of the TV.
Power Supply
Short-circuit
Breaker
yyVentilation
Install your TV where there is proper
ventilation. Do not install in a confined space
such as a bookcase. Do not cover the product
with cloth or other materials while plugged.
Do not install in excessively dusty places.
yyIf you smell smoke or other odors coming
from the TV, unplug the power cord and
contact an authorized service center.
yyKeep the product away from direct sunlight.
yyNever touch this apparatus or antenna during
a thunder or lightning storm.
yyWhen mounting a TV on the wall, make sure
not to install the TV by hanging the power and
signal cables on the back of the TV.
yyDo not allow an impact shock or any objects to
fall into the product, and do not drop anything
onto the screen.
yyAs long as this unit is connected to the AC
wall outlet, it is not disconnected from the AC
power source even if the unit is turned off.
yyDo not attempt to modify this product in
any way without written authorization from
LG Electronics. Unauthorized modification
could void the user’s authority to operate this
product.
yyOutdoor Antenna Grounding (Can differ by
country):
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 as
death or serious injury can occur. 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 the
U.S.A. 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 National
Electrical Code, ANSI/NFPA 70
yyDisconnecting the Main Power
The power outlet used with this device must
remain easily accessible.
yyStore the accessories (battery, etc.) in a safe
location out of the reach of children.
yyThis apparatus use batteries. In your
community there might be regulations that
require you to dispose of these batteries
properly due to environmental considerations.
Please contact your local authorities for
disposal or recycling information.
yyDo not dispose of batteries in a fire.
yyDo not short circuit, disassemble or allow the
batteries to overheat.

yyGenerated Sound
For USA and Canada
“Cracking” noise: A cracking noise that
occurs when watching or turning off the TV
is generated by plastic thermal contraction
due to temperature and humidity. This noise
is common for products where thermal
deformation is required.
Electrical circuit humming/panel buzzing: A
low level noise is generated from a high-
speed switching circuit, which supplies a large
amount of current to operate a product. It
varies depending on the product.
This generated sound does not affect the
performance and reliability of the product.
yyTake care not to touch the ventilation
openings. When watching the TV for a long
period, the ventilation openings may become
hot. This does not affect the performance of
the product or cause defects in the product.
yyIf the TV feels cold to the touch, there may
be a small “flicker” when it is turned on. This
is normal, there is nothing wrong with TV.
Some minute dot defects may be visible on
the screen, appearing as tiny red, green, or
blue spots. However, they have no adverse
effect on the TV’s performance. Avoid
touching the LCD screen or holding your
finger(s) against it for long periods of time.
Doing so may produce some temporary
distortion effects on the screen.

CHILD SAFETY:
It Makes A Difference How and Where
You Use Your Flat Panel Display
Congratulations on your purchase! As you enjoy your new product,
please keep these safety tips in mind:
THE ISSUE
y The home theater entertainment experience is a growing trend and
larger flat panel displays are popular purchases. However, flat panel
displays are not always supported on the proper stands or installed
according to the manufacturer’s recommendations.
y Flat panel displays that are inappropriately situated on dressers,
bookcases, shelves, desks, speakers, chests or carts may fall over and
cause injury.
THIS MANUFACURER CARES!
y The consumer electronics industry is committed to making home
entertainment enjoyable and safe.
TUNE INTO SAFETY
y One size does NOT fit all. Follow the manufacturer’s
recommendations for the safe installation and use of your flat panel
display.
y Carefully read and understand all enclosed instructions for proper use
of this product.
y Don’t allow children to climb on or play with furniture and television
sets.
y Don’t allow place flat panel displays on furniture that can easily be
used as steps, such as a chest of drawers.
y Remember that children can become excited while watching
a program, especially on a “larger than life” flat panel display.
Care should be taken to place or install the display where it cannot be
pushed, pulled over, or knocked down.
y Care should be taken to route all cords and cables connected to the
flat panel display so that they cannot be pulled or grabbed by curious
children.
WALL MOUNTING: IF YOU DECIDE TO WALL MOUNT
YOUR FLAT PANEL DISPLAY, ALWAYS:
y Use a mount that has been recommended by the display
manufacturer and/or listed by an independent laboratory
(such as UL, CSA, ETL).
y Follow all instructions supplied by the display and wall mount
manufacturers.
y If you have any doubts about your ability to safely install your flat
panel display, contact your retailer about professional installation.
y Make sure that the wall where you are mounting the display is
appropriate. Some wall mounts are not designed to be mounted
to walls with steel studs or old cinder block construction.
If you are unsure, contact a professional installer.
y A minimum of two people are required for installation.
Flat panel displays can be heavy
