the control function is separate from the control chan-

Alternatively you can set Input 8 to “no transmitter

Here too, “Input 8” should also be programmed – if
applicable, for all flight phases – to “free” by way of
the »Control adjust« menu. However, it is simpler
to separate control function “8” from control channel
“8” using the »Mix-only channel« menu – see page
216. This applies to all flight phases, and is available
as standard on the mc-20 HoTT transmitter only.
