13. Outdoor Antenna grounding-If an outside antenna or
cable system is connected to the TV/VCR, 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 thelead-in wire toan antenna discharge unit,
size of grounding conductors, location of antenna-dis-
charge unit, connection to grounding electrodes, and re-
quirements for the grounding electrode. (Fig. A)
14. Lightning-For added protection for this TV/VCR re-
ceiver during a lightning storm, or when it is left unat-
tended andunused for long periods of time, unplug it from
thewall outlet anddisconnect the antenna or cable system.
This will prevent damage to the TV/VCR 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 or 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.
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/VCR through openings as they may touch
dangerous vokage points or short out parts that could
result in a fire or electric shock. Never spill liquid of any
kind on the TVNCR.
18. Servicing-Do not attempt to service this TV/VCR your-
self 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/VCR 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
flayed.
b. If liquid has been spilled, or objects have fallen into the
TV/VCR.
c. If the TVNCR has been exposed to rain or water.
d. If the TV/VCR 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 technician to
restore the TV/VCR to its normal operation.
e. If the TVNCR has been dropped or damaged in any way.
f. When the TV/VCR exhibits a distinct change in perform-
ance-this indicates a need for service.
20. Replacement Parts-When replacement parts are re-
quired, be sure the service technician has used replace-
ment parts specified by the manufacturer that have the
same characteristics as the original part. Unauthorized
substitutions may result in fire, electric shock, injury to
persons or other hazards.
21. Safety Cheek-Upon completion of any service or repairs
to this TVNCR, ask the service technician to perform
routine safety checks to determine that the TV/VCR is in
proper operating condition.
