INTERFERENCE CAUSES

The most up-to-date technology to eliminate an interference is incorporated in your television receiver. Local conditions, however, can create the disturbances which visibly affect your picture. Proper installation, good antenna connection and following advice of your dealer are your best safeguards against the following disturbances.

The most common type of television disturbances are as follows:

IGNITION

Black spots or horizontal streaks may appear, picture may flutter or drift. Usually caused by interference from automobile ignition system, neon lamps, electrical drills and other electrical appliances.

GHOSTING

Ghostings 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 the reception.

SNOW

lf your receiver is located at the fringe area of a television station where the signal is weak, your picture may be blurred 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 the loss of the contrast in picture.
