RECEPTION PROBLEMS
• 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.
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.
