Which button in the remote I have to use to switch from TV to Radio on Amiko A5 combo 4k?

Using Amiko A5 combo 4k it is possible to listen radio from satellite? Which button in the remote control unit (RCU) I have to use to switch from TV to Radio?

I use Hot-Bird at 13°E.

I found a way to use the Remote Control Unit (RCU) to listen the radio station from satellite. When I watch the tv station I push the button

"OK" and after the "Red" button and after I select "Radio" group and select a radio station.

The problem is solved. I share my workaround to the community.
