13 An outside antenna system should not be locat-
ed 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.
14 Do not overload wall outlets and extension
cords as this can result in fire or electric shock.
15 Never push objects of any kind into this televi-
sion equipment 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
television equipment.
16 Do not attempt to service this television equip-
ment yourself as opening or removing covers
may expose you to dangerous voltage or other
hazards. Refer all servicing to qualified service
personnel.
17 Unplug this television equipment 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 television equipment.
(c) If the television equipment has been exposed
to rain or water.
(d) If the television equipment does not operate
normally by following the operating instruc-
tions. Adjust only those controls that are
covered by the operating instructions as an
improper adjustment of other controls may
result in damage and will often require
extensive work by a qualified technician to
restore the TV receiver to its normal opera-
tion.
(e) If the television equipment has been
dropped or the cabinet has been damaged.
(f) When the television equipment exhibits a
distinct change in performance - this indi-
cates a need for service.
18 When replacement parts are required, be sure
the service technician has used replacement
parts specified by the manufacturer that have
the same characteristics as the original part.
Unauthorized substitutions may result in fire,
electric shock or other hazards.
19 Upon completion of any service or repairs to
this television equipment, ask the service
technician to perform safety checks to deter-
mine that the television is in a safe operating
condition.
20 If an outside antenna or cable system is con-
nected to the television receiver, be sure the
antenna or cable system is grounded so as to
provided some protection against voltage
surges and built-up static charges.
Section 810 of the National Electrical Code,
ANSI/NFPA N0.70-1984, 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 ground-
ing electrodes, and requirements for the ground
ing electrode.
