• 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, lightning rods,
or gas pipes.

• 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 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 benzene.
• 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.
• 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.
• Do not allow an impact shock, any objects to fall
into the product, and do not drop anything onto
the screen.
• 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.
• Batteries
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.
• Do not use high voltage electrical equipment
near the TV, (e.g., a bug zapper.)
This may result in product malfunction.
• 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
