• If an outside antenna or cable system is
connected to the television, make sure the
antenna or cable system is grounded to
provide some protection against voltage
surges and built-up static charges. Article
810 of the National Electrical Code,
ANSI/NFPA 70, provides information with
regard 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.

• Use No. 10AWG (5.3 mm
8AWG (8.4 mm
2
(1.0 mm ) copper-clad steel or bronze
wire, or larger, as a ground wire.
• Secure antenna lead-in and ground wires
to house with stand-off insulators spaced
from 4-6 feet (1.22-1.83 m) apart.
• Mount antenna discharge unit as close as
possible to where lead-in enters house.
• Use jumper wire not smaller than No.
6AWG (13.3 mm
equivalent, when a separate
antenna-grounding electrode is used. See
ANSI/NFPA70.
• An outside antenna system should not be
located in the vicinity of overhead power
circuits, or where it can fall into such power
lines or circuits. When installing an outside
antenna system, extreme care should be
taken to keep from touching such power lines
or circuits as contact with them might be fatal.

• For added protection for this television during
a lightning storm, or when it is left unattended
and unused for long periods of time, unplug it
from the power outlet and disconnect it from
the antenna or cable system. This prevents
damage to the television due to lightning and
power line surges.
• Do not overload power outlets and extension
cords, because overloading can cause a fire
or electric shock.
• Never push objects of any kind into this
television through slots in the case, because
they may touch dangerous voltage points or
short out parts that could result in a fire or
electric shock. Never spill liquid of any kind
on the television.
• Do not attempt to service this television
yourself, because opening or removing
covers may expose you to dangerous
voltages or other hazards. Refer all servicing
to qualified service technicians.
• Unplug this television from the power outlet
and refer servicing to qualified service
technicians under the following conditions:
• When the power cord or plug is damaged
or frayed.
• If liquid has been spilled into the
television.
• If the television has been exposed to rain
or water.
• If the television does not operate normally
by following the operating instructions.
Adjust only those controls that are
covered by the operating instructions,
because incorrect adjustment of other
controls may result in damage and often
requires extensive work by a qualified
technician to restore normal operation.
• If the television has been dropped or the
case has been damaged.
• When the television exhibits a distinct
change in performance.
• When replacement parts are required, be
sure the service technician has used
replacement parts specified by the
manufacturer that have the same
characteristics as the original part.
Unauthorized substitutions may result in fire,
electric shock, or other hazards.
• Upon completion of any service or repairs to
this television, ask the service technician to
perform routine safety checks to determine
that the television is safe to operate.

OTE TO CABLE TELEVISION SYSTEM INSTALLER
This reminder is provided to call the cable
television system installer's attention to Section
820 40 of the NEC which provides guidelines for
proper grounding and, in particular, specifies
that the cable ground shall be connected to the
grounding system of the building, as close to the
point of cable entry as practical.
