IMPORTANT SAFEGUARDS, cont’d.
12. 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.
13. Overloading
Do not overload wall outlets and extension cords as this can result in a risk of re or electric shock.
14. Object and Liquid Entry
Never push objects of any kind into this TV through openings as they may touch dangerous voltage points or
short-out parts that could result in re or electric shock. Never spill liquid of any kind on or into the TV.
15. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the TV, be
sure the antenna or cable system is grounded so as to provide
some protection against voltage surges and built-up static charges.
Section 810 of the National Electric Code, ANSI/NFPA No. 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.
16. Servicing
Do not attempt to service this TV yourself as opening or removing covers may expose you to dangerous volt-
age or other hazards. Refer all servicing to qualied service personnel.
17. Damage Requiring Service
Unplug the TV from the wall outlet and refer servicing to qualied service personnel under the following condi-
tions:
(a) When the power-supply cord or plug is damaged.
(b) If liquid has been spilled, or objects have fallen into the TV.
(c) If the TV has been exposed to rain or water.
(d) If the TV 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 qualied technician to restore the TV to its normal
operation.
(e) If the TV has been dropped or the cabinet has been damaged.
(f) When the TV exhibits a distinct change in performance - this indicates a need for service.
18. Replacement Parts
When replacement parts are required, be sure the service technician has used replacement parts specied by
the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result
in re, electric shock or other hazards.
19. Safety Check
Upon completion of any service or repair to the TV, ask the service technician to perform safety checks to
determine that the TV is in safe operating condition.
