• 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.
