Re)ception 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 unit 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 TVNCR/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. f 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 unit from the power source 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. 72

Re)
ception
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
unit
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
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.
GHOSTS
[
If
the
TVNCR/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.
SNOW
f
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
unit
from
the
power
source
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.
