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 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/VCR receiv-
er 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/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 voltage points or short out parts that could
result in a fire or electric shock. Never spill liquid of any
kind on the TV/VCR.
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 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/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
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 TV/VCR has been dropped or damaged in any way.
f. When the TV/VCR exhibits a distinct change in perfor-
mance-this indicates a need for service.
20. Replacement Parts-When replacement parts are required,
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 TV/VCR 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.
