Reception disturbances

NOTE:
• The TV set can generate sound distortion in external devices such as a radio. Please separate radio equipment from the TV set to a
considerable distance.
IGNITION NOISE:
Black spots or horizontal streaks may appear, picture may flutter or drift. Usually caused by interference
from automobile ignition systems, neon lamps, electrical drills, and other electrical appliances.
GHOSTS:
Ghosts are caused by the television signal following two paths. One is the direct path and the other
is reflected from tall buildings, hills or some other objects. Changing the direction or position of the
antenna may improve reception. Ghosting may also be caused by defects in the antenna system such
as unshielded leads or connecting several sets to the same antenna without using multiple antenna
couplers.
SNOW:
If your receiver is located in the fringe area of a television station where the signal is weak, your
picture may be marred by the appearance of small dots. When the signal is extremely weak, it may be
necessary to install a special antenna to improve the picture.
RADIO FREQUENCY INTERFERENCE:
The interference produces moving ripples or diagonal streaks, and in some cases, causes loss of
contrast in the picture.
