RECEPTION DISTURBANCE

The most common types of television interference are as follows.
IGNITION
Black spots or horizontal streaks may appear, picture may flutter or drift.
Usually caused by interference from car ignition systems, neon lamps, electrical
drills 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 object.
Changing the direction or position of the antenna may improve the reception.
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.
PICTURE SIZE VARIATION
A slight picture size variation is normal when you adjust the CONTRAST or
BRIGHTNESS control.
CARE AND MAINTENANCE
To prevent fire or shock hazard, disconnect the TV/VCR from the AC power source before cleaning. The finish on
the cabinet may be cleaned with mild soap and a soft damp cloth. Take care when cleaning or wiping the plastic
parts.
