>When you have set up the test transponder, press Back, to return to the menu for setting up the motorized rotating antenna. The field used to enter the orbital position will be active.

>Use the numeric keys to enter the orbital position of the user satellite and confirm by pressing OK.

>Now press the OK key to indicate whether it is a west-

erly (W) or an easterly (E) orbital position.

If the Geo-positioningfunction is set to On (Point 9.2) you can now rotate the antenna dish to the programmed user satellite position by using the function Turn to Sat (Point 9.4.1).

If the Geo-positioningfunction is set to Off, you will have to rotate the antenna manually to the desired satellite position (Point 9.3.2.2).

9.3.2 Adjusting the satellite antenna

To be able to point the antenna at a particular satellite, and to confirm whether you are receiving the correct satellite at the position set, a test transponder has been set up for each satellite.

The exact positioning of the antenna is only made possible by the indicator showing the signal strength and quality of the test transponder.

9.3.2.1 Configuring the test transponder and LNC

 

To change the parameters of the test transponder concerned,

 

proceed as follows:

 

>

Use the arrow keys to mark the field Current

>

Press OK to open the satellite list.

 

>

Use the arrow keys up/down to mark the satellite

 

 

position for which you wish to change the data.

 

>

Confirm by pressing OK.

Press Back to return to the settings for the motor

 

 

antenna.

9.3.2.2 Manual positioning of antenna

You can establish the optimum position of the antenna by working according to the indication of signal strength and sig- nal quality. Adjust the antenna so that the maximum values are achieved on both bar graphs.
