4 IMPORTANT SAFETY INSTRUCTIONS
y 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).
Short-circuit
Breaker
Power Supply
y 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
y 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.
y 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.
y 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.
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.
y 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
on the product.
This generated sound does not affect the
performance and reliability of the product.
y 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.
y 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
y 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.
y 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.
y 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.

y 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.
y 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.
y 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.
y If you smell smoke or other odors coming from
the TV, unplug the power cord and contact an
authorized service center.
y Keep the product away from direct sunlight.
y Never touch this apparatus or antenna during a
thunder or lightning storm.
y When 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.
y Do not allow an impact shock or any objects to fall
into the product, and do not drop anything onto
the screen.
y Disconnecting the Main Power
The power outlet used with this device must
remain easily accessible.
y Store the accessories (battery, etc.) in a safe
location out of the reach of children.
y This 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.
y Do not dispose of batteries in a fire.
y Do not short circuit, disassemble or allow the
batteries to overheat.
y Dot Defect
The Plasma or LCD panel is a high technology product
with resolution of two million to six million pixels.
