RECEPTION PROBLEMS - 45 -
When the batteries run down, remote control operation will become erratic or possibly stop altogether.
Replace the old batteries with two new "AA" size batteries.
Exposure of the viewing screen to prolonged direct sunlight or heat may cause the screen to permanently
warp, resulting in a distorted picture.
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, 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.
NOTE: The TV set can generate sound distortion in external devices such as a radio.
Please separate radio equipment from the TV set to a considerable distance.
