This equipment has been tested and found to com­ply with the limits for a Class B digital device, pur­suant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference in a residential installation. This
equipment generates, uses and can radiate radio fre­quency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However,
there is no guarantee that interference will not
occur in a particular installation. If this equipment
does cause harmful interference to radio or televi­sion reception, which can be determined by turning
the equipment off and on, the user is encouraged to
try to correct the interference by one or more of
the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment
and receiver.

- Connect the equipment to an outlet on a circuit
different from that to which the receiver is con­nected.

- Consult the dealer or an experienced radio/TV
technician for help.

Any changes or modifications not expressly
approved by the party responsible for compliance
could void the user’s authority to operate the
equipment.

without written authorization from LG Electronics.
Unauthorized modification could void the user’s
authority to operate this product

The lightning flash with arrowhead
symbol, within an equilateral triangle,

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.

The exclamation point within an equilateral

triangle is intended to alert the user to
the presence of important operating and main­tenance (servicing) instructions in the literature
accompanying the appliance.

TO REDUCE THE RISK OF ELECTRIC SHOCK

or pinched particularly at plugs, convenience
receptacles, and the point where they exit from
the apparatus.

Only use attachments/accessories specified by
the manufacturer.

Use only with the cart, stand, tripod, bracket,
or table specified by the manufacturer, or sold
with the apparatus. When a cart is used, use
caution when moving the cart/apparatus com­bination to avoid injury from tip-over.

Unplug this apparatus during lighting storms
or when unused for long periods of time.

Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has
been damaged in any way, such as power­supply cord or plug is damaged, liquid has
been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to
rain or moisture, does not operate normally, or
has been dropped.

SAFETY INSTRUCTIONS

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.

GGRROOUU NNDDIINNGG
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.

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.
