Switch assignment

I'm frustrated! I can't figure out how to access the channel/switch assignment panel. the manual say "click on the model icon" . Where?

I'm trying to assign channel 6 to the "H" switch for a simple up and down/bang-bang action.

FOUND IT! This Youtube video: "How to setup Jumper T8SG with a BNF Racer". Explains switch assignment, dual/triple rates, expo. Easy to understand.Intended for drone flyers, but the info can easily be translated into planes. Already set up a Spitfire with flaps and retracts and a glider with 3 position slats. Really easy once you learn how to get where you can do what you want.

Oh yes. I found the info I needed in the first 6 or 8 minutes. didn't have to watch all 27 mins.
