Reception disturbances

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
interference are shown below. If one of these symptoms appear when the TV/DVD is connected to a Cable
TV system, the disturbance may be caused by the local Cable TV company broadcast.
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.
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.
SNOW
If the TV/DVD 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.
CARE AND MAINTENANCE
To prevent fire or shock hazard, disconnect the TV/DVD from the power source before cleaning.
Use caution when cleaning or wiping the plastic parts.
