This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable pro-
tection against harmful interference in a residen-
tial installation. This equipment generates, uses
and can radiate radio frequency energy and, if not
installed and used in accordance with the
instructions, may cause harmful interference to
radio communications. However, there is no
guarantee that interference will not occur in a
particular installation. If this equipment does
cause harmful interference to radio or television
reception, which can be determined by turning
the equipment off and on, the user is encour-
aged to try to correct the interference by one or
more of the following measures:
- Reorient or relocate the receiving antenna.
-Increase the separation between the equip-
ment and receiver.

technician for help.
This device complies with part 15 of the FCC
Rules.
Operation is subject to the following two condi-
tions: (1) This device may not cause (harmful)
interference, and (2) this device must accept
any interference received, including interference
that may cause undesired operation (of the
device).

SAFETY INSTRUCTIONS
®
@
Never touch this apparatus or antenna during
a thunder or lighting storm.
When mounting a TV on the wall, make sure
not to install the TV by the hanging power
and signal cables on the back of the TV.
Do not allow an impact shock or any objects
to fall into the product, and do not drop onto
the screen with something.
CAUTION concerning the Power Cord:
It is recommend that appliances be placed
upon a dedicated circuit; that is, a single
outlet circuit which powers only that appli-
ance 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, exten-
sion 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, discon-
tinue use of the appliance, and have the cord
replaced with an exact replacement part by
an authorized servicer. 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 use a damaged or loose power cord.
Do not pull on the power cord to unplug the
TV. Grasp the plug when unplugging the
power cord.
WARNING - To reduce the risk of fire or elec-
trical 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 appara-
tus (e.g. on shelves above the unit).
0GROUNDING
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 ground-
ed 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.

ANTENNAS
Outdoor antenna grounding
If an outdoor antenna is installed, follow the
precautions below. An outdoor antenna sys-
tem 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 $10 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 elec-
trodes and requirements for the grounding
electrode.

Cleaning
When cleaning, unplug the power cord and
rub gently with a soft cloth to prevent
scratching. Do not spray water or other liquids
directly on the TV as electric shock may occur.

tion. Do not install in a confined space such
as a bookcase. Do not cover the product
with cloth or other materials (e.g.) plastic
while plugged in. Do not install in exces-
sively dusty places.
Take care not to touch the ventilation open-
ings. When watching the TV for a long
period, the ventilation openings may
become hot.
If you smell smoke or other odors coming
from the TV or hear strange sounds, unplug
the power cord contact an authorized service
center.

FEATURE OF THIS TV
_ Some of these features are not available on all models.
CLEAR
VOICE II
High-definition television. High-
resolution digital television broadcast
and playback system composed of
roughly a million or more pixels, 16:9
aspect-ratio screens, and AC3 digital
audio. A subset of digital television,
HDTV formats include lOSOi and 720p
resolutions.
AV Mode is three preset picture and
audio settings. It allows the viewer to
quickly switch between common set-
tings. It includes Cinema, Sports, and
Game Modes.
A unique invisible speaker system
tuned by renowned audio expert, Mr.
Mark Levinson. Speakers are embed-
ded in strategic spots behind the front
cabinet and use minute vibrations to
turn the entire front bezel into the
speaker system. The result s a clean,
polished look, and enhanced audio by
increasing the "sweet spot", giving a
wider and richer sound field.
Automatically enhances and amplifies
the sound of human voice frequency
range to help keep dialogue audible
when background noise swells.
Unlike other sensors which can only
sense brightness of ambient light, LG's
"Intelligent Sensor" uses 4,096 sens-
ing steps to evaluate its surroundings.
Using a sophisticated algorithm, the LG
processes picture quality elements
including brightness, contrast, color,
sharpness and white balance. The result
is a picture optimized for it's surround-
ings, more pleasing to watch and which
can also save up to 50% in power con-
sumption.
