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.

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
lightning storm.
y When mounting a TV on the wall, make sure not
to install the TV by hanging the power and signal
4
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 DEVICE FROM THE MAIN
POWER
The power plug is the disconnecting device.
In case of an emergency, the Power Plug must
remain readily accessible.
y Batteries
Store the accessories (battery, etc.) in a safe
location out of the reach of children.
y 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.
y Do not dispose of batteries in a fire.
y Do not short circuit, disassemble, or allow the
batteries to overheat.
y Do not use high voltage electrical equipment
near the TV, (e.g., a bug zapper). This may result in
product malfunction.
y 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
Antenna Lead in Wire
dots are deactivated pixels and do not affect the

y Generated Sound
Grounding Conductor
(NEC Section 810-21)
Cracking noise A cracking noise that occurs
Power Service Grounding
when watching or turning off the TV is
Electrode System
(NEC Art 250, Part H)
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.
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 Do not install this product on a wall if it could be
exposed to oil or oil mist. This may damage the
product and cause it to fall.
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
