Ignition Noise
Black spots or horizontal streaks may appear; picture may flutter or drift. This is usually
caused by interference from automobile ignition systems, neon lamps, electrical drills, and
other electrical appliances.
NOTE: The TV set can generate sound distortion in external devices such as radios. Please separate radio equipment from the TV
set to a considerable distance.

IFFICULTIES
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 other objects. Changing the direc-
tion or position of the antenna may improve reception. Ghosting may also be caused by
defects in the antenna system, such as unshielded leads. Or it may be caused by connect-
ing 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
This form of interference produces moving ripples or diagonal streaks, and in some
cases, causes loss of contrast in the picture.
