Important Safeguards
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 cir-
cuits as contact with them might be
fatal.
14
Do not overload wall outlets and exten-
sion 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 remov-
ing covers may expose you to dangerous
voltage or other hazards. Refer all servic-
ing to qualified service personnel.
17
Unplug this television equipment from
the wall outlet and refer servicing to
qualified service personnel under the fol-
lowing 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 equip-
ment.
(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 dam-
aged.
(f) When the television equipment
exhibits a distinct change in perfor-
mance - this indicates a need for ser-
vice.
18
When replacement parts are required, be
sure the service technician has used
replacement parts specified by the manu-
facturer that have the same characteris-
tics 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 protec-
tion 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 anten-
na-discharge unit, connection to ground-
ing electrodes, and requirements for the
grounding electrode.
