• Grounding
- (Except for devices which are not grounded)
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, lightning
rods, or gas pipes.

• As long as this unit is connected to the AC wall
outlet, it is not disconnected from the AC power
source even if the unit is turned off.
• Do not attempt to modify this product in any
way without written authorization from LG
Electronics. Unauthorized modification could
void the user’s authority to operate this product.
• 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.

• Cleaning
- When cleaning, unplug the power cord and
wipe gently with a soft cloth to prevent
scratching. Do not spray water or other liquids
directly on the TV as electric shock may occur.
Do not clean with chemicals such as alcohol,
thinners, or benzene.
• Moving
- Make sure the product is turned off,
unplugged, and all cables have been removed.
It may take 2 or more people to carry larger
TVs. Do not press or put stress on the front
panel of the TV.
• Ventilation
- Install your TV where there is proper
ventilation. Do not install in a confined space
such as a bookcase. Do not cover the product
with cloth or other materials while plugged in.
Do not install in excessively dusty places.
• If you smell smoke or other odors coming from
the TV, unplug the power cord and contact an
authorized service center.
• If water or another substance enters the
product (like an AC adapter, power cord, or TV),
disconnect the power cord and contact the
service center immediately. Otherwise, this may
result in fire or electric shock.
• Use only an authorized AC adapter and power
cord approved by LG Electronics.
Otherwise, this may result in fire, electric shock,
malfunction, or product deformation.
• Never disassemble the AC adapter or power
cord. This may result in fire or electric shock.
