Uniden UST-9000 - Manual (Page 12)

Helpful Hints
To make sure you get the most out of satellite television
viewing we offer the following information. The sophisticat­
ed engineering required to tune in satellite signals from about
22,000 miles away can be as mysterious as space itself. We
hope that this information will take some of the mystery out
of this technology, making it even more enjoyable for you.
External Interference
The most common cause of interference for a satellite televi­
sion system is terrestrial interference. It is caused by local
telephone or data microwave links. If your antenna is located
close to, or In the path of a microwave tower you may experi­
ence snowy video, sparkles or a distorted picture. This kind of
interference is usually not constant and may appear to
increase and decrease at different times of the day. Since
telephone traffic is busiest during the daytime you may notice
the most interference during daytime viewing. You may also
notice that this interference occurs only on vertical or hori­
zontal channels. On the back of the UST-9000 is a switch
labeled Tl ON/OFF. If you experience terrestrial interference
turn the Tl filter on. If the problem still exists you may need to
relocate your antenna or use more sophisticated filters. Con­
tact your Uniden dealer for more information.
Solar Outage
Another cause of interference is the bi-annual solar outage.
Due to the seasonal changes of the earth's axis the satellite
belt moves between the earth and the sun. When the satel­
lite belt moves directly between the sun and your antenna,
the satellite transmissions will be overpowered by the natural
radio transmissions of the sun. This kind of satellite eclipse
occurs twice a year around the spring and fall equinox. As the
satellite eclipse approaches you may notice a gradual, daily
increase in interference. It will peak for about 1 0 - 3 0 minutes
Troubleshooting
with a completely distorted picture. As the eclipse decreases
so will the amount of interference until the picture is back to
clear, normal operation. The degree of interference and th
timing of this phenomenon varies with the satellite, your geo­
graphical location and the size of your antenna. Unfortunate­
ly the only solution is to tune to a satellite that is east of the
sun's position until it has passed the satellite you were
watching.
Other Sources of Interference
All electrical equipment is susceptible to interference from
other electrical devices. The UST-9000 is an extremly sensitive
unit and may pick up interference from any household appli­
ance. If you experience temporary audio or video interference
you should check other equipment in your house. Appliances
such as refrigerators, washers/dryers, microwave ovens,
pumps, power tools, hair dryers, etc. may cause a variety of
annoying interference. Also, radio transmitters such as CBs or
shortwave radios may be a source of interference. Try plug­
ging the UST-9000 into another outlet, or isolated circuit.
Check with your Uniden dealer for other ways to control this
type of interference.
Aircraft passing over or near to your antenna may cause
some temporary interference as it blocks or reflects the satel­
lite signal. This type of interference is momentary and cannot
be filtered.
Western USA Installation |
If your UST-9000 is installed west of the Rocky Mountains
you will need to reverse the installation of the actuator.
Install the actuator arm on the left side of the antenna and
reverse the -t- and - connections on the back of the UST-
9000 so that the East and West keys operate properly.
If your UST-9000 is not performing up to your expectations,
please try the simple steps listed below. If you cannot get
satisfactory results after following these steps, contact your
local Uniden dealer or call the Uniden Customer Service
Center at 1-317-842-2483, 9am - 5pm EST.
NOTE: Over 80% of the problems occurring with satellite
TV systems are related to cable trouble. If you are experienc­
ing any problem with your^system, first check all cables and
connections carefully. If the problem still exists try the follow­
ing steps.
A. Problem
The indicator lights on the receiver are not working. No vid­
eo or audio.
Solution:
1. Check the Power switch to make sure it is on.
2. Check the AC power cord to make sure It is plugged into
an outlet that is not controlled by a wall switch.
3. Check the main circuit breaker on the back of the unit.
B. Problem
The indicator lights are on but no TV picture or audio.
Solution:
1. Check the power switch on the TV or monitor. Check the
cable between the RF Out connector on the back of the
unit and the VHF In on the TV set. Make sure both con­
nections are secured.
2. Check the channel selector on the TV to be sure it is set to
3 or 4 and that the 3/4 switch on the back of the unit is set
to the same number.
3. Check to see if the P.L LED is on. Parental Lock may be
engaged. ,
4. Check another channel on the satellite. The current onfc
may not have any programming.
