• 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 reflectedfrom tall buildings,hills or some other objects.Chang-
ing 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 con-
necting several sets to the same antenna without using multiple antenna couplers.
• SNOW:
If your receiver is located in the fringe area of a television stationwhere 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.
