Reception Disturbances; Care And Maintenance - Memorex MT1098 Owner's Manual

RECEPTION DISTURBANCES

Most types of television interference can be remedied by adjusting the height and posi-
tion 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 symp-
toms appear when the TV 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 appli-
ances 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 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 CON-
TRAST or BRIGHTNESS settings.

CARE AND MAINTENANCE

To prevent fire or shock hazard, disconnect the TV from the DC 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.
