Why won't my Torrent 110 connect to BetaFlight?

I must be missing something obvious, as my Gremlin talks to BetaFlight just fine. But I picked up a Torrent 110 yesterday, and would like to reassign the Arm and Flight Mode switches, and the connection fails every time. What am I overlooking?

Thanks in advance,
