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,

English

 

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.
