13 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.
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
television 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 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 instructions. 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 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
indicates 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 determine that the television is in a safe
operating condition.
20 If an outside antenna or cable system is
connected 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 grounding
electrodes, and requirements for the
grounding electrode.
