RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE.
REFER TO QUALIFIED SERVICE PERSONNEL.

This symbol is intended to alert the user to the presence of

uninsulated “dangerous voltage” within the product’s
enclosure that may be of sufficient magnitude to constitute a risk
of electric shock to persons.

This symbol is intended to alert the user to the presence of

important operating and maintenance (servicing)
instructions in the literature accompanying the appliance.

WARNING: TO REDUCE THE RISK OF FIRE AND ELECTRIC SHOCK, DO
NOT EXPOSE THIS PRODUCT TO RAIN OR MOISTURE.

• TO PREVENT THE SPREAD OF FIRE, KEEP CANDLES OR OTHER ITEMS
WITH OPEN FLAMES AWAY FROM THIS PRODUCT AT ALL TIMES.

• Do not place the TV and/or remote control in the following

environments:

- Keep the product away from direct sunlight.

- An area with high humidity such as a bathroom.

- Near any heat source such as stoves and other devices that produce

heat.

- Near kitchen counters or humidifiers where they can easily be

exposed to steam or oil.

- An area exposed to rain or wind.

- 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).

- Near flammable objects such as gasoline or candles, or expose the

TV to direct air conditioning.

- Do not install in excessively dusty places.

Otherwise, this may result in fire, electric shock, combustion/
explosion, malfunction or product deformation.

• Ventilation

- Install your TV where there is proper ventilation. Do not install in a

confined space such as a bookcase.

- Do not install the product on a carpet or cushion.

- Do not block or cover the product with cloth or other materials

while unit is plugged in.

• Take care not to touch the ventilation openings. When watching the
TV for a long period, the ventilation openings may become hot.

• 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 device.

• Do not move the TV whilst the Power cord is plugged in.

• Do not use a damaged or loosely fitting power cord.

• Be sure to grasp the plug when unplugging the power cord. Do not
pull on the power cord to unplug the TV.

• Do not connect too many devices to the same AC power outlet as this

• Disconnecting the Device from the Main Power

- The power plug is the disconnecting device. In case of an

emergency, the power plug must remain readily accessible.

• Do not let your children climb or cling onto the TV. Otherwise, the TV
may fall over, which may cause serious injury.

• 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 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.

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

cable holders may break, and injuries and damage to the TV
may occur.

• When attaching the stand to the TV set, place the screen
facing down on a cushioned table or flat surface to protect
the screen from scratches.

Mounting on a Table

1 Lift and tilt the TV into its upright position on a table.

performed by a qualified professional installer. We recommend the use
of LG’s wall mount bracket. LG’s wall mount bracket is easy to move with
cables connected. When you do not use LG’s wall mount bracket, please
use a wall mount bracket where the device is adequately secured to the
wall with enough space to allow connectivity to external devices. It is
advised to connect all the cables before installing fixed wall mounts.

• Do not mix new batteries with old batteries. This may cause
the batteries to overheat and leak.

• Failure to match the correct polarities of the battery may
cause the battery to burst or leak, resulting in fire, personal
injury, or ambient pollution.

• This apparatus uses 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.

• The product's internal and external batteries should not be
exposed to excessive heat such as direct sunlight, fire, or
the like.

Troubleshooting

The software version can be updated for improvement in performance.

Customer needs to ensure the compatibility of customer’s equipment
with LGE software. If needed, please consult with LGE and upload
revised software version according to the guidance provided by LGE.

Cannot control the TV with the remote control.

• Check the remote control sensor on the product and try again.

• Check if there is any obstacle between the product and the remote
control.

• Check if the batteries are still working and properly installed ( to

, to ).

No image display and no sound is produced.

• Check if the product is turned on.

• Check if the power cord is connected to a wall outlet.

• Check if there is a problem in the wall outlet by connecting other
products.

The TV turns off suddenly.

• Check the power control settings. The power supply may be
interrupted.

• Check if the auto-off func tion is activated on the settings related
time.

• If there is no signal while the TV is on, the TV will turn off
automatically after 15 minutes of inactivity.

When connecting to the PC (RGB/HDMI), no signal is detected.

• Turn the TV off/on using the remote control.

• Reconnect the RGB/HDMI cable.

• Restart the PC with the TV on.

Abnormal display

• If the product feels cold to the touch, there may be a small “flicker”
when it is turned on. This is normal, there is nothing wrong with
product.

• This panel is an advanced product that contains millions of pixels.
You may see tiny black dots and/or brightly coloured dots (red, blue
or green) at a size of 1ppm on the panel. This does not indicate a
malfunction and does not affect the performance and reliability of
the product. This phenomenon also occurs in third-party products
and is not subject to exchange or refund.

• You may find different brightness and colour of the panel depending
on your viewing position(left/right/top/down).
This phenomenon occurs due to the characteristic of the panel. It is
not related with the product performance, and it is not malfunction.

• Displaying a still image for a prolonged period of time may cause
image sticking. Avoid displaying a fixed image on the TV screen for a
long period of time.

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 per formance and
reliability of the product.

• When cleaning the product, be careful not to allow any
liquid or foreign objects to enter the gap between the
upper, left or right side of the panel and the guide panel.
(Depending on model)

ENGLISH

• Make sure to wring any excess water or cleaner from the
