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 appliance
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, extension
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, discontinue 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 make the TV with the power cord
plugged in. Do not use a damaged or loose
power cord. Be sure do grasp the plug when
unplugging the power cord. Do not pull on the
power cord to unplug the TV.

WARNING - To reduce the risk of fire or electrical
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 apparatus (e.g.
on shelves above the unit).

G

ROUN DING

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.

D

ISCONNECTING DEVICE FROM MAINS

Mains plug is the disconnecting device. The
plug must remain readily operable.

As long as this unit is connected to the AC wall
outlet, it is not disconnected from the AC
power source even if you turn off this unit by

NTE N NAS
Outd o or ant en na gro un di ng

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.

ntenna grounding according to the
National Electrical Code, ANSI/NFPA 70

Cle a ning

When cleaning, unplug the power cord and
scrub gently with a soft cloth to prevent

for professional certification by the Imaging Science
Foundation. The resulting ISF “day” and “night” modes
will then be accessible by the user to experience the
best their LG HDTV has to offer.
CALIBRATE LIKE A PRO: Sophisticated and detailed

of roughly a million or more pixels, 16:9 aspect-ratio
screens, and AC3 digital audio. A subset of digital
television, HDTV formats include 1080i and 720p
resolutions.

■

When a fixed image (e.g. logos, screen menus, video game, and computer display) is displayed on the TV

for an extended period, it can become permanently imprinted on the screen. This phenomenon is known
as “image burn” or “burn-in.” Image burn is not covered under the manufacturer’s warranty.

■

In order to prevent image burn, avoid displaying a fixed image on your TV screen for a prolonged period

(2 or more hours for LCD, 1 or more hours for Plasma).

■

Image burn can also occur on the letterboxed

areas of your TV if you use the 4:3 aspect
ratio setting for an extended period.

Screw length needed depends on the wall mount
used. For further information, refer to the instruc­tions included with the mount.

G

Standard dimensions for wall mount kits are shown
in the table.

G

When purchasing our wall mount kit, a detailed
installation manual and all parts necessary for
assembly are provided.

G

Do not use screws longer then the standard dimen­sion, as they may cause damage to the inside to
the TV.

G

For wall mounts that do not comply with the VESA

standard screw specifications, the length of the
screws may differ depending on their specifica­tions.

G

Do not use screws that do not comply with the
VESA standard screw specifications.

Do not use fasten the screws too strongly, this may
damage the TV or cause the TV to a fall, leading to
personal injury. LG is not liable for these kinds of
accidents.

SECURING THE TV TO THE WALL TO PREVENT FALLING
WHEN THE TV IS USED ON A STAND

We recommend that you set up the TV close to a wall so it cannot fall over if pushed backwards.
Additionally, we recommend that the TV be attached to a wall so it cannot be pulled in a forward direction,

potentially causing injury or damaging the product.
Caution: Please make sure that children don’t climb on or hang from the TV.

■

Insert the eye-bolts (or TV brackets and bolts) to tighten the product to the wall as shown in the picture.

*If your product has the bolts in the eye-bolts position before inserting the eye-bolts, loosen the bolts.
* Insert the eye-bolts or TV brackets/bolts and tighten them securely in the upper holes.

Secure the wall brackets with the bolts (sold separately) to the wall. Match the height of the bracket that is
mounted on the wall to the holes in the product.

Ensure the eye-bolts or brackets are tightened securely.

■

Use a sturdy rope (sold separately) to tie the produ

ct. It is safer to tie

the rope so it becomes horizontal between the wall and the product.

■

You should purchase necessary components to prevent the TV from tipping over (when not using a wall mount).

■

Image shown may differ from your TV.

G

Use a platform or cabinet strong enough and large enough to support the size and weight of the TV.

G

To use the TV safely make sure that the height of the bracket on the wall and the one on the TV are the same.
