Rece tion Problems
J
,, iGNiTiON NOISE:
Black spots or horizontal streaks may appear, picture may flutter or drift.
UsuaIly caused by interference from automobile ignition systems, neon
Iamps, ebctricaI drilb, and other electrical appIiances.
,, GHOSTS:
Ghosts are caused by the television signal folIowing two paths. One is the
direct path and the other is reflected from talt buiIdings, hills or some other
objects. Changing the direction or position of the antenna may improve
reception. Ghosting may abo be caused by defects in the antenna system
such as unshieided leads or connecting severaI 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 signat is weak, your picture may be marred by the appearance of small
dots. When the signal is extremeIy weak, it may be necessary to instaII a
speciaI 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.
