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 cir-
cuits 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 tele-
vision 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
equipment yourself as opening or removing
covers may expose you to dangerous volt-
age 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 condi-
tions:
(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 cov-
ered by the operating instructions as an
improper adjustment of other controls may
result in damage and will often require exten-
sive work by a qualified technician to restore
the TV receiver to its normal operation.
(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.

When replacement parts are required, be
sure the service technician has used replace-
ment parts specified by the manufacturer

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 informa-
tion 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.
