ANTENNA
Unless your TV set is connected to a cable TV system or to a centralized antenna
system, a good outdoor color TV antenna is recommended for the best performance.
However, if you are located in an exceptionally good signal area that is free from
interference and multiple image ghosts, the indoor antenna may be sufficient.
LOCATION
Select an area where sunlight or bright indoor illumination will not fall directly on the
picture screen. Also, be sure that the location selected allows a free flow of air to and
from the perforated back cover of the TV set.
To prevent damaging the TV, do not leave the set in a place where the temperature
becomes too hot. For example, exposed to direct sunlight or near a heating device, etc.
VIEWING
This TV set may be viewed from any desired distance. Most view er s pr efer a distance of
