Most types of television interference can be remedied by adjusting the height and position of the VHF/UHF
antenna. Outdoor antennas are recommended for best results. The most common types of television interfer-
ence are shown below. If one of these symptoms appear when the TV/VCR is connected to a Cable TV system,
the disturbance may be caused by the local Cable TV company broadcast.
GHOSTS
Ghosts are caused by the television signal following two paths. One is the
direct path and the other is reflected by tall buildings, hills or other large
objects. Changing the direction or position of the antenna may improve the
reception.
IGNITION
Black spots or horizontal streaks may appear, the picture may flutter or
drift. Usually caused by interference from automobile ignition systems,
neon lamps or AC powered tools and appliances such as drills or hair
dryers.
SNOW
If the TV/VCR is located far from the TV station, in a fringe reception
area where the signal is weak, small dots may appear in the picture.
If the signal is extremely weak, the installation of a larger external
antenna may be necessary.
RADIO FREQUENCY INTERFERENCE (RFI)
Caused by two-way radios, this type of interference produces moving
ripples or diagonal streaks in the picture. Some cases may cause a loss of
contrast in the picture. Changing the direction and position of the antenna
or installing an RFI filter may improve the picture.
PICTURE SIZE VARIATION
A slight picture size variation is normal when you adjust the CONTRAST or
BRIGHTNESS settings.
CARE AND MAINTENANCE
To prevent fire or shock hazard, disconnect the TV/VCR from the AC power sources before cleaning.
The finish on the cabinet may be cleaned with mild soap and a soft, damp cloth and cared for as other furniture. Use
caution when cleaning or wiping the plastic parts.
