EXAMPLE OF ANTENNA GROUNDING AS PER
13. Outdoor Antenna grounding-If an outside antenna or cable
system is connected to the TV, be sure the antenna or
cable system is grounded so as to provide some protec-
tion against voltage surges and built-up static charges.
Article 810 of the National Electrical Code, ANSI/NFPA
No. 70, 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. (Fig. A)
14. Lightning-For added protection for this TV receiver during
a lightning storm, or when it is left unattended and unused
for long periods of time, unplug it from the wall outlet and
disconnect the antenna or cable system. This will prevent
damage to the TV due to lightning and power-line surges.
15. Power Lines-An outside antenna system should not be
located in the vicinity of overhead power lines or other
electric light of 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 touch-
ing such power lines or circuits as contact with them might
be fatal.
16. Overloading-Do not overload wall outlets and extension
cords as this can result in a risk of fire or electric shock.
17. Object and Liquid Entry-Never push objects of any kind
into this TV through openings as they may touch danger-
ous voltage points or short out parts that could result in a
fire or electric shock. Never spill liquid of any kind on the
TV.
18. Servicing-Do not attempt to service this TV yourself as
opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified
service personnel.

19. Damage Requiring Service-Unplug this TV from the wall
outlet and refer servicing to qualified service personnel
under the following conditions:
a. When the power supply cord or plug is damaged or
frayed.
b. If liquid has been spilled, or objects have fallen into the
TV.
c. If the TV has been exposed to rain or water.
d. If the TV does not operate normally by following the
operating instructions. Adjust only those controls that
are covered by the operating instructions, as improper
adjustment of other controls may result in damage and
will often require extensive work by a qualified techni-
cian to restore the TV to its normal operation.
e. If the TV has been dropped or damaged in any way.
f. When the TV exhibits a distinct change in performance,
this indicates a need for service.
20. Replacement Parts-When replacement parts are required,
be sure the service technician uses replacement parts
specified by the manufacturer that have the same charac-
teristics as the original part. Unauthorized substitutions
may result in fire, electric shock, injury to persons or other
hazards.
21. Safety Check-Upon completion of any service or repairs to
this TV, ask the service technician to perform routine safe-
ty checks to determine that the TV is in proper operating
condition.
