13.Outdoor Antenna gi'ounding-If an outside antenna or
cable system is connected to the TVNCR, 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 re-
quirements for the grounding electrode. (Fig. A)
14.Lightning-For added protection for this TV/VCR 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 TVNCR 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 touch-
ing such power lines or circuits as contact with them might
be fatal.
16.Overloading-D0 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 voltage po:mtsor 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 TVNCR yourself
as opening or removing covers may expose you to danger-
ous voltage or other hazards. Refer all servicing to quali-
fied service personnel.

19.Damage Requiring Service-Unplug this TVPCCR 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/VCR.
c. If the TV/VCR 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 adjust-
ment 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 TV/VCR 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 repl_icemeflt parts ai'e'reqfiired,
be sure the service technician has used 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/VCR, ask the service technician to perform
routine safety checks to determine that the TVNCR is in
proper operating condition.
22.Heat-This TV/VCR product should be situated away from
heat sources such as radiators, heat registers, stoves, or
other products (including amplifiers) that produce heat.
