How do I show notes I play?

[Mikrdk]

Hi. Can anyone help me so that my PSR-775 will display the notes I play on a note sheet way?

Asking AI and looking in the manual the closest I got was the "SCORE" view that shows notes from a song, but doesn't show the notes I'm playing. AI says "you may need to (...) be in performance mode for the Score display to show the notes effectively", but I don't know how to get in this mode.
