EXAMPLE OF ANTENNA GROUNDING AS PER
S 2 8 9 8 A
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 protection 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-dis-
charge 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 exten-
sion 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
dangerous 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 dan-
gerous 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 per-
sonnel 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
characteristics as the original part. Unauthorized substitu-
tions 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 safety checks to determine that the TV is in proper
operating condition.
22. HEAT - This TV product should be situated away from
heat sources such as radiators, heat registers, stoves, or
other products (including amplifiers) that produce heat.
