How can I add transponders to the BV 4-50 DVB-T/S module? Is there an additional service manual available?

I bought a new BV 4-50 with a built-in Sat-module. I can't find a menu for editing satellite settings (e.g. adding transponders).

I bought a new Sat-module for my old BV 3-32. Here I can find the menu "Edit satellite settings"

Very strange to have different menu-behaviors for the same product....
