I don't know from experience.
But the description of the Sataccess card on this site says here: "The Sataccess SRG SSR card with the proven Swiss CI Viaccess module as a bundle.
Works in all SAT receivers with CI slot."
This receiver has a CI+-capable slot, which as far as I know should be backwards compatible with CI. So it should work. The shape of the module makes the Sataccess module look compatible with the UPC module that I use, but in DVB-C cable reception.
You could also ask Technisat yourself on their German website.

Thank you very much for the quick reply.
