FIRST TIME INSTALLATION
Multisatellite/two port DiSEqC
Select this alternative if your antenna system has two LNBs and
when you are not using any of the alternatives on the lines
5 - 6 from the menu “Antenna/satellite selection” on page 13.
• Make the selections for LNB type, LNB offset voltage (if nec-
essary), satellite and predefined channel (see Multisatellite/
mini DiSEqC above for an explanation of the different alterna-
tives) for switch 1.
• Press OK.
• Make the selections for switch 2.
• Press OK.
Proceed with the channel search. Refer to page 18.
For each LNB you connect to the DiSEqC switch, the fol-
lowing configuration has to be performed.
As an example the following part will describe how the LNB in-
tended for Astra 1 will be configured to the DiSEqC input A on
the switch and the LNB intended for Hotbird to DiSEqC input B.
LNB type
Select “Universal” or the local oscillator (L. O.) frequency valid
for the connected LNB.
LNB Offset voltage
If the cable down from the antenna is very long, the voltage at
the LNB could be too low to change the polarization. You can in-
crease the voltage to the LNB by 0,5 V.
Satellite
In this example, select Astra 1 because its LNB is connected to
the DiSEqC A input on the switch.
Predefined channel
Select one of the predefined channels and adjust the antenna as
described on page 14, “Antenna adjustment and signal check”.
Before you can continue, a TV picture from the predefined chan-
nel must be visible in the background.
When you do have a picture press OK to continue with DiSEqC
port B. The same procedure as for Astra 1 has to be repeted. But
this time select Hotbird as the satellite.
When the configuration of DiSEqC B is ready, press OK.
Proceed with the channel search. Refer to page 18.
