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.
