accordance with the manufacturer’s instructions.

Do not install near any heat sources such as
radiators, heat registers, stoves, or other apparatus
(including amplifiers)that produce heat.

Do not defeat the safety purpose of the polarized
or grounding-type plug. A polarized plug has
two blades with one wider than the other. A
grounding type plug has two blades and a third
grounding prong, The wide blade or the third
prong are provided for your safety. If the provided
plug does not fit into your outlet, consult an
electrician for replacement of the obsolete outlet.

Protect the power cord from being walked on
or pinched particularly at plugs, convenience

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).

GGRROOUUNNDDIINNGG
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 grouned 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.

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.

VESA WALL MOUNTING

Install your wall mount on a solid wall perpendicular to the floor. When attaching to other building materi­als, please contact your nearest dealer.

If installed on a ceiling or slanted wall, it may fall and result in severe personal injury.
We recommend that you use an LG brand wall mount when mounting the TV to a wall.

GG

Do not install your wall mount kit while the TV is plugged in. It may result in personal injury due to electric
shock.

CAUTION

GG

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

GG

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

GG

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

GG

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

GG

For wall mounts that do not comply with the VESA

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

GG

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

Do not tighten the screws too much. It may dam­age the TV or allow the TV to a fall and cause per­sonal injury. LG is not liable for these kinds of acci­dents.

GG

LG is not liable for TV damage or personal injury
when a non-VESA or non specified wall mount is
used or the consumer fails to follow the TV installa­tion instructions.

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

We recommend that you set 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 eye-bolts (or TV brackets and bolts) to attach 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 screws (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 or cord (sold separately) to tie the product. It is
safer to tie the rope so it becomes horizontal between the wall and
the product (the less slack in the rope, the better).

■

You should purchase necessary components to prevent TV from falling off of the stand.

■

Image shown may differ from your TV.

* This feature is not available for all models.

GG

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

GG

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.

NOTE:

If the pillow speaker switch is set to Pillow Speaker, no

Use a pillow speaker that is a UL recognized pendant control
bearing the warning:

“Risk of fire if used in oxygen enriched atmosphere. Keep pen-

dant control away from oxygen equipment.”

Controlling the TV with Serial Data

The TV is capable of being controlled by a single-wire, serial data
signal. This is a LG patented technology and is being implemented
by certain brands of “smart” pillow speakers.

Pillow Speaker Interface

This connector furnishes three control lines and an audio output.
A patient-pendant remote control, or entertainment audio and
nurse call system may be connected here. All lines are isolated
from the AC power line and earth ground. (Optoisolators isolate
the control lines, and a transformer isolates the audio. There are
no relays or inductive components in the control lines.)

Controlling the TV with Mechanical Switches

Pin 4(common) is momentarily connected to pin
1, 3, or 6 via push-action switches to control
On/Off and Channel Up/Down. These pins are
at +13volts DC(when measured from pin4) with
the switches open. Current draw is 8 mA when a
switch is closed. (This operation is identical to
previous LG models using the 5-Wire Interface
except that only +7 volts DC was supplied and
current draw was only 2.5 mA.)
