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.

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. LG recommends that wall mounting be performed by a qualified professional installer.
GG
Do not install your wall mount kit while your TV is turned on. 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 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 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.
You should purchase necessary components to prevent TV from falling off of the stand.
Image shown may differ from your TV.
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.
