IMPORTANT SAFETY INSTRUCTIONS IMPORTANT SAFETY INSTRUCTIONS
y 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.

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