IMPORTANT SAFETY INSTRUCTIONS
 Protect the power cord from being walked on
or pinched particularly at plugs, convenience
receptacles, and the point where they exit
from the apparatus.
 Only use attachments/accessories specified
by the manufacturer.
 Use 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.
 Unplug this apparatus during lightning storms
or when unused for long periods of time.
 Refer 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.
 Do not stick metal objects or any other
conductive material into the power cord. Do
not touch the end of the power cord while it
is plugged in.
 Keep the packing anti-moisture material or
vinyl packing out of the reach of children. Anti-
moisture material is harmful if swallowed. If
swallowed by mistake, induce vomiting and
go the nearest hospital. Additionally, vinyl
packing can cause suffocation. Keep it out of
the reach of children.
 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 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.
 Warning - To reduce the risk of fire or
electrical shock, do not expose this product
to rain, moisture or other liquids. Do not
touch the TV with wet hands. Do not install
this product near flammable objects such
as gasoline or candles, or expose the TV to
direct air conditioning.
 Do not expose to dripping or splashing and
do not place objects filled with liquids, such
as vases, cups, etc. on or over the apparatus
(e.g. on shelves above the unit).

4IMPORTANT SAFETY INSTRUCTIONS
 Grounding
(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.
Short-circuit
Breaker
Power
Supply
 As 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.
 Do 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.
 Outdoor 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.

 Cleaning
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.
 Moving
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.
 Ventilation
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.
 If you smell smoke or other odors coming
from the TV, unplug the power cord and
contact an authorized service center.
 Keep the product away from direct sunlight.
 Never touch this apparatus or antenna during
a lightning storm.
 Do not allow an impact shock, any objects to
fall into the product, and do not drop anything
onto the screen.
 Disconnecting the Main Power
The power outlet used with this device must
remain easily accessible.
 Store the accessories (battery, etc.) in a safe
location out of the reach of children.
 This apparatus uses 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.
 Do not dispose of batteries in a fire.
 Do not short circuit, disassemble, or allow
the batteries to overheat.

IMPORTANT SAFETY INSTRUCTIONS
 Dot Defect
The panel is a high technology product with
resolution of two million to six million pixels.
In a very few cases, you could see fine dots
on the screen while you’re viewing the TV.
Those dots are deactivated pixels and do not
affect the performance and reliability of the
TV.
 Generated Sound
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 upon the product.
This generated sound does not affect the
performance and reliability of the product.
 Take 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.
 If 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.
Preventing image burn or burn-in on your
TV screen
 If a fixed image displays on the TV screen for
a long period of time, it will be imprinted and
become a permanent disfigurement on the
screen. This is image burn or burn-in and not
covered by the warranty.
 If the aspect ratio of the TV is set to 4:3 for a
long period of time, image burn may occur on
the letterboxed area of the screen.
 Avoid displaying a fixed image on the TV
screen for a long period of time (2 or more
hours for LCD, 1 or more hours for the
Plasma TV) to prevent image burn.
