Important Safeguards- 3
13. An outside antenna system should not be
located in the vicinity of overhead power
lines or other electric light or power
circuits, 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 the 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.
