RECEPTION DISTURBANCE
The most common types of television interference are as follows:
IGNITION :
Black spots or horizontal lines may appear ; picture may flutter or drift. Usually caused by interference from automobile ignition systems, neon lamps, electric drills and other electric 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 other objects. Changing the direction or position of the antenna may improve the reception.
SNOW:
If you are located on the fringes of a television reception area, the signal will be weak, and your picture may contain many small dots. When the signal is extremely weak, it may be necessary to install an external antenna to improve the picture.
RADIO FREQUENCY INTERFERENCE:
This interference produces moving ripples or diagonal streaks, and in some cases causes loss of contrast in the picture.
PICTURE SIZE VARIATION:
A slight variation in picture size is normal when you adjust the
CONTRAST or BRIGHTNESS controls.
NOTE : If you subscribe to a cable service and any these symptoms appear, the problem may be caused by the cable company.
CARE AND MAINTENANCE
To prevent fire or shock hazard, disconnect your unit from the AC power source when cleaning. The finish on the receiver may be cleaned with a dust cloth and cared for as other furniture.
Use caution when cleaning and wiping the plastic parts. Mild soap and a soft, damp cloth may be used.
