Q. Dolby Digital (AC-3) bit stream Output (S/P DIF).
A. STB (limit to the model which has S/P DIF terminal) supports the Stream Output function of Dolby Digital (Project name AC-3) which enables the customers to enjoy the 5.1 channel digital sound when the S/P DIF terminal in STB rear panel is connected with an Amplifier embedded Dolby Digital decoder or appropriable decoder.
STB supports only the Dolby Digital stream output and customers have to additionally buy the Dolby Digital decoder because that is not embedded in STB. Even though customers have all equipment, it is not possible to receive the Dolby Digital in a way of 5.1 Channel when the channel (service) you are watching is not carrying Dolby encoding audio.

Q. There is no power when I switch on my receiver
A. Check the power lead of STB is plugged in the mains and switched on. Ensure that the power switch is on at the back of the receiver.
|
Q. I cannot get a picture on my TV from my receiver
A. First, if you are using SCART, make sure it is connected to your STB and also to your TV. Make sure that you are using the correct Audio/Video input channel on your TV. If you are using an RF lead, confirm it is connected to your receiver and your TV. Make sure that you have tuned your TV correctly.
|
Q. I can receive a good picture but no sound
| A. Check the audio mute controls on both receiver and TV. Check the volume controls on both receiver and TV. If your STB is connected to your TV via RF lead, make sure that you have selected the correct PAL Setting for your region in the "UHF Tuning" menu |
Q. The remote controller does not work
| A. Replace the batteries. Point the remote controller towards the receiver |
Q. How can I find satellite with my STB?
A. It is very easy to build in receiving antenna system by using STB. And you can do as below :
|
Step 1: Site. At first, you must know the right vertical line direct to earth's equator from your position and your local latitude, longitude as well as the position of satellite that you want to receive signal from. Then figure out the right 3 angles: azimuth, elevation and polarization angle.
(Note: Be sure there is no trees, buildings and other obstruction exist between antenna and satellite.)
Step 2: Setting. Including antenna setting and STB setting. Antenna setting is a physical work that include floor or wall drilling, antenna assemble and LNB setting. In order to adjust the 3 angles mentioned above, you should not tighten the relative bolts here, just screw them in their position and do not let the linking parts move free. But you'd better set the polarization angle as precise as you can so that you have only two angles to adjust later. Then go to STB setting. Connect your STB,TV set and antenna correctly. Power on your receiver and go to Main Menu. Select "Antenna setting" and set all the parameter correctly: including satellite name, L.O Frequency and switch state according to the device you used. After this press OK to save the setting and go to "Transponder Setting", select the satellite name you have set just now and then select "Add new transponder". Enter the Frequency and Symbol Rate, select the correct polarization and then do not do anything else to your STB. The STB setting is over and go to next step.
Step 3: Direction. When you come here, just move the antenna slowly from left to right, up and down as zigzag orbit until the signal appear on the TV screen. Then adjust that 3 angles to make signal strength up to Max value and tighten all the bolts. Thus the whole antenna setting is over. Take the Remote Controller again and select Search = Yes, then press OK to search programs. The result will be appear several seconds later. Press EXIT and then press MENU, you can enjoy Digital Satellite TV program now.
Q. How do I search for a transponder manually?
A. Enter the main menu and select transponder setting. Select the satellite you want to use and select "Add new transponder" and then enter the Frequency, Symbol Rate and Polarization of the transponder that you require and the right Eb/No can display, set Search = Yes and press OK on the remote control unit. The search will start now
Q. I keep getting the Eb/No = 0% when I try a manual search
A. Make sure that your dish is aligned correctly first. Then confirm that you are selected the right satellite and all the parameters are setting correctly. Otherwise check the information whether the Transponder's beam cover your area and the EIRP is strong enough
Q . How can I get the information about satellite worldwide including
A. You can find this information in many websites on the internet. for example, , http://www.watinternational.com/page/page/733038.htm, or you can find these channel listings in various satellite publications.
Q. How many channels can be stored on my receiver?
Please visit the "Products" section.
Q . Why the order of channels' list is broken when I try to store one
This is most likely that you have reached the maximum bouquet limit of your STB. You should delete some bouquets in order to store more channels
Q. "No(or Bad) Signal" message on TV screen
There are lots of possibilities.
-> Check your dish and LNB condition such as position and even cable status.
-> Check connection of antenna and the STB.
-> If you are using DiSEqC1.0 switch, please check the DiSEqC1.0 switching
function works normally.
-> We have a request saying that this problem was gone when changed the LNB.
-> Please check the signal is good and covers your area.
-> In addition, other possible factor are temperature and tuner. The temperature
of a room or LNB can affect operation.
-> Check the current software version and upgrade with the latest version only if
the current version is out of date.
-> It is likely that updated the wrong software from PC. If this is the case, you'd
better upgrade your receiver's software again with correct software version.

About Grounding the System
About Grounding the System
|
Grounding the satellite system to the central building ground helps protect it and other components from lightning damage. Different brands of satellite systems may have special grounding requirements. However, dish installation should comply with local codes and the National Electrical Code (NEC). Refer to your satellite system’s user guides for any other additional grounding information. Grounding the satellite system is something you can probably do yourself. But if you’re not sure, you should contact a qualified electrician. Acceptable central building ground points
• Grounded interior metal cold water pipe within five feet of the point where it enters the building.
• Grounded metallic service raceway.
• Grounded electrical service equipment enclosure.
• Eight-foot grounding rod driven into the ground (only if bonded to the central building ground by #6 or heavier bonding wire).
• Other acceptable grounding electrodes that comply with sections 250 and 810 of the National Electrical Code (NEC).
***The United States National Electrical Code specifies that coaxial cable that is exposed to lightning shall be connected to the grounding system of the building as close to the point of cable entry as possible
|
Routing and Grounding the Cables |
- Attach the grounding block to the side of your house close to the point you have chosen as the coaxial cable entry point. You may have to use anchors, togglers, or wood screws depending on the surface on which you are mounting the grounding block.
- Route the coaxial cable and messenger (ground) wire from the bottom of the mast to the grounding block.
- Make a 3"- 5" drip loop using cable clips at the grounding block. This will prevent water from running into the connection at the grounding block.
- Place some silicone grease on the connector and connect the coaxial cable to the grounding block.
- Secure the messenger (ground) wire to the grounding block.
- Locate the central building ground.
- Use a grounding wire (#10 copper or #8 aluminum) that will extend from the grounding block to the central building ground. Attach the grounding wire to the grounding block by placing it through the wire hole in the grounding block and tightening the screw.
- Route the grounding wire from the grounding block to the central building ground, and connect to the central building ground.

Dish Pointing Tips
|
To get a signal, a satellite dish must be pointed directly at the satellite, with NO obstructions between the two.
This means NO trees and NO buildings.
To determine where the satellite you are looking for is located, use our satellite look angle and azimuth .
Once you have obtained that information, use a compass to determine the location of the satellite from your property.
When you look for obstacles that may be in the path of the signal (according to the look angle and the azimuth of the satellite), take into consideration future tree growth, house remodeling or additions and new construction in your area.
- The satellite signal WILL NOT PASS through leaves or branches.
- The satellite signal WILL NOT PASS through glass; don't try to install your dish indoors!
Where are the satellites located anyway?
The satellites are located 22,000 miles above the equator.
In Canada, depending on where you live, the satellites highest above your head will have an elevation angle between 30 and 45 degrees and the most westerly and most easterly satellites will have an elevation angle between 15 and 10 degrees (vice-versa if you live on the West coast). |
LNBF Polarization Tilt (skew)
| LNBF Polarization Tilt (skew) |
-
Your LNB is marked with a label indicating the polarization tilt. Your local LNB polarity offset information varies by location. If you are in Houston, TX your LNB polarization is to be set at 0 degrees. But if you are on the California coast your LNB polarization could be as much as minus 30 degrees (clockwise rotation). And if you are in Maine your LNB polarization could be as much as plus 30 degree (counter-clockwise rotation). Peaking the dish and adjusting the polarity of the LNB will greatly improve your Signal Quality reading.
-
When adjusting your LNB, it's not going to be turned more than 31 degrees (unless you live in Hawaii). Also be sure you don't leave that LNB plastic bracket loose. The LNB won't pick up the satellite if the bracket is loose, and it's slightly off. Finally, when thinking about degrees, remember that 30 degrees is about 5 minutes on a clock. Don't turn the LNB too much!
-
Make certain that the pole or tri-mast assembly is vertically plumb. Check it with an Angle Finder or a level. If the pole or tri-mast is not plumb, your azimuth and elevation will not be accurate and will cause difficulty when pointing the dish. Also, if you are using a pole mount, make certain you pour a sufficient footing that will provide proper ballast. A pole that does not have sufficient ballast will lean over time, causing you to lose the signal. Your mount must be very strong and can not wobble. You must use at least 4 lag screws (correct size for your installation) in the base mount one on each corner.
-
When pointing the satellite dish, allow 5-10 seconds between any movements of the dish. This allows the receiver to complete a signal scan, and lock indicating that you have located the signal.
-
A reasonable signal strength is between 50 and 80. If it is lower than that range, you are either pointing into an object (e.g. trees, shrubs, or structures) or pointing above or below the satellite. Your antenna installation position must have a clear view angle of the satellite you are trying to receive.
-
There are other satellites within 2 degrees to the left or right that may use the same frequency. This will provide a strong signal strength reading but no signal quality or signal lock. If you have a high strength reading but are not able to lock on, try adjusting the dish slightly to the right or left.
-
When you are attempting to set up a satellite dish in a heavily wooded area or one with lots of man made obstructions, it helps to understand how the dish really works. One common misconception is that the dish points 'directly' at the satellite. This isn't the case for most dish designs. The apparent elevation of the dish is 15 or more degrees lower than it's actual receiving window. Have a look at this diagram.... it's easier to see it than it is to explain it..... |
Q: What is USALS system?
Q: What is USALS system?
A: It is a calculation system processed by Stab and given free to all satellite recivers' or PC cards' manufacturers, enabling the reciver to calculate the positon of all satellites in orbit with a precision lower than 0,1 deg. with reference to the installation site. All this in a completely automic mode and with no specific technical knowledge required.Please remember 'USALS" is a program and not a communication protocol as alternative to "DiSEqC1.2" protocol string has been defined to drive the motor in "Drive motor to Angular Position (0)" mode, which is the only ocommand utilized by "USALS" program. We can therefore affirm that the "USALS" program is an advanced option of the "DiSEqC1.2" protocol
