Video Switcher; Tv Antenna; Tv And Radio Interference; Miscellaneous Appliances - Fleetwood Southwind 1995 Owner's Manual

Video Switcher
The video switcher, located on top of the VCR, allows
routing olthe antenna, cable orVCR signals to both the
front and rear TVs independent of each other. You can
also use the switcher to record or pass through the
signals from the antenna or cable hookup.
TV ANTENNA
The roof-mounted antenna is designed for reception of
VHF and UHF television signals.
Before traveling, remember to lower the antenna and
secure it to prevent damage to the antenna, motor
home roof, or objects in the path of the antenna, such
as overhead wires. DO NOT TRAVEL WITH THE
ANTENNA RAISED.
NOTE: The antenna boosterpowersupply must
be turned off to prevent battery drain. A red
indicator light will glow when the unit is on.
TV AND RADIO INTERFERENCE
The television and radio systems in your RV have been
chosen to provide good performance under varied
signal conditions. Occasionally, though, you may expe-
rience "ghosts" on TV, "flutter" when listening to FM
broadcasts, or other signal interference.
The fault is normally not with your receiver. Neither is
your antenna system usually at fault. The idea that
antennas, whether amplified or not, "pull in" a signal is
a popular misconception. An antenna does not pull a
signal out of air by virtue of its "power". The antenna
only responds to signals present at the antenna ele-
ments. Antennas with boosters only amplify these
signals.
Since distance from the broadcast tower is critical to
reception clarity, remember that TV and FM signals
have a range of only about 75 miles under the best of
atmospheric and geographic conditions. The good re-
ception you get at parks located at great distances from
broadcast facilities is probably the result of satellite,
microwave or other cable distribution systems. The
antenna on your RV is no competition for these very
expensive installations.
In addition, TV and radio frequency interference results
from the electromagnetic fields produced by electric arc
discharge. This arcing is found in lightning, vehicle igni-
tion systems, and in 12 volt DC (brush type) motors used
47
in power vents and furnaces. Note that nearly every DC
motor has brushes. Most alternating current (AC) motors
do not have brushes, and therefore do not generate the
arcing interference. This is why this type of interference
is less noticeable in a household environment.
As the signal diminishes with distance and geographi-
cal features (mountains, etc.), the effect of electric arc
interference may become more and more noticeable.
Eventually, the signal will be overcome by the interfer-
ence. The following suggestions can improve reception:
•
•
•
•
Use the "park cable" TV antenna system of
your RV in remote areas rather than the roof
antenna if the campground provides cable
hook-Up.
Turn the television antenna. Sometimes turn-
ing the antenna will pick up a stronger signal.
Try turning or rotating the antenna throughout
its range. You may find your signal in a very
unexpected direction.
With FM stereo signals, switch the unit to
MONO, if possible. Some of the phase and
noise components of a stereo signal will dis-
appear in MONO mode.
Reduce the treble setting to reduce back-
ground noise. Although not yielding the best
high-frequency performance, at least you may
be able to reduce the irritation of the distortion
and noise.
MISCELLANEOUS APPLIANCES
You may have additional appliances in your unit which
operate only when connected to 120-volt power from
either a public utility or the generator.
In some cases appliance selector switches are pro-
vided on the galley to allow you a selection of appli-
ances yet still remain within the power capacity of the
electrical system.
Washer/Dryer Drain Screen
(Optional on selected models)
The removable drain screen which protects the pump
from lint and foreign matter needs to be cleaned peri-
odically. See your Owner's Information Package for
more details.
