IMPORTANT SAFETY INSTRUCTIONS
•
Outdoor Antenna Grounding
If an outside antenna or cable system
is connected to the product, 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 into 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.
Article 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 rub gently with a soft cloth to prevent
scratching. Do not spray water or other
liquids directly on the STB as electric shock
may occur. Do not clean with chemicals such
as alcohol, thinners, or benzene.
•
Transporting Product
Make sure the product is turned Off and
unplugged and that all cables have been
removed. Do not press against or put stress
on the STB.
•
Ventilation
Install the STB 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 (e.g.,
plastic) while it is plugged in. Do not install in
excessively dusty places.

•
Do not touch the ventilation openings, as
they may become hot while the STB is
operating.
•
If you smell smoke or other odors coming
from the STB or hear strange sounds, unplug
the power cord, and contact an authorized
service center.
•
Keep the product away from direct sunlight.
•
Unplug this apparatus during lightning storms
or when unused for long periods of time.
•
Keep the packing anti-moisture material or
vinyl packing out of the reach of children.
Anti-moisture material is harmful if
swallowed. If swallowed by mistake, force
the patient to vomit and visit the nearest
hospital. Additionally, vinyl packing can
cause suffocation. Keep it out of the reach of
children.
•
Do not stick metal objects or any other
conductive material into the power cord. Do
not touch the end of the power cord while it
is plugged in.
•
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).
•
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, lightening 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.
