Use the   arrow keys to select the demodulatoion type. Press ENTER.
1) If you select the Mode as DVB-DSNG, the selectable types are
dependant upon your purchased FAST options.
2) If you select the Mode as DVB-S, this screen is 'status only' and the
cursor rests under QPSK.
3) If you select the Mode as DVB-S2, this screen is 'status only' and the
demodulation type is automatically determined. Before
synchronization of the Rx path, the cursor may reside in any position.
After synchronization (i.e., the Rx TRAFFIC LED is Green), re-enter the
Type menu to update the display; the cursor will rest under the
demodulation type.
Press ENTER or CLEAR to return to the previous menu.
