Basic Operation

• After turning on the receiver and positioning the antenna, the first WorldSpace broadcaster should be audible.
• If there is adequate signal strength and no WorldSpace audio is available, search for the broadcasters (see Select Beam Mode section).
• Press the Broadcaster Select (BC) buttons to select the broadcaster:
  * Top button to select the next broadcaster
  * Bottom button to select the previous broadcaster
• As the BC Select buttons are pressed, the broadcaster ID is displayed on the screen, followed by the broadcaster label, if available.
• For each BC, the Service Channel programs (SC)s are shown. Press the Service Components Select button to select the SC within the BC.

Select Beam Mode

This section does not apply if after completing basic set-up and basic operation you are receiving WorldSpace audio content. If no broadcasters can be heard and the display window shows an adequate signal strength, please follow these instructions:

• Press the Beam Select button on top of the receiver. The name of the current beam will appear in the display.
• Continue to press the Beam Select button until the display reads "BEAM AFRI -- 1". The receiver is beginning to search.
• If a signal is detected, a satellite icon will appear on the top right corner of the display window. If no signal is detected, the display will continue to read "BEAM AFRI -- 1".
• If the search is successful, the 1st broadcaster will be heard and the rest of the broadcasters will be in memory. Follow the directions in the Basic Operations section to tune through the broadcasters.

Reception: Line-of-Sight (LOS)

Line-of-Sight (LOS), refers to uninterrupted or "obstruction-free" sight to the AfriStar satellite. LOS is a very important precondition for receiving any satellite service.

How do you obtain Line-of-Sight (LOS)?

Very simple - your reception antenna (e.g. patch antenna, high gain antenna, dish, ...) must have free sight to the satellite – with no obstructions such as trees, houses, bridges or the like.

Imagine the satellite as a point in the sky in the direction determined by consulting the antenna pointing guide. Check for anything in the way of clear line-of-sight. Avoid or remove any such objects.

Also, consider that objects may move or be moved in front of your reception antenna without your control, such as a car, bus, or truck. Therefore, carefully select the location for placing or mounting the antenna. In general, the basic guidelines for LOS of TV satellite reception systems apply to the WorldSpace system as well.

Reception: Indoors

For in-building reception of the WorldSpace signal when there is no line-of-sight (LOS), an antenna must be aimed out of a glass window, or must be placed outside. WorldSpace offers extension cables and other inexpensive accessories to enable LOS reception.

Reception: Interference

Interference - what is it and what will cause it?

An interference of the WorldSpace signal is caused by one or more unwanted signals near the WorldSpace frequency. These disturbances may make reception of the WorldSpace signal difficult.  If you suspect that your WorldSpace reception is suffering from interference, there are solutions.   However, it is recommended that if possible you contact your WorldSpace receiver dealer to discuss the problem.

To eliminate interference, WorldSpace provides two solutions. The quickest and most efficient solution is the interference filter.  A special antenna with higher antenna gain may also be installed.  With the WorldSpace Interference Filters the receivers can easily receive and decode the program signals.

A filter and a high gain antenna may block out the offending interference.

WorldSpace Frequency Band

The WorldSpace digital satellite system broadcasts in the so called "L" band frequencies (1467-1492 MHz), which was allocated for this Direct Audio Broadcast Service at the World Administrative Radiocommunication Conference of 1992.
