This is a 6EX 2.4GHz transmitter and it does not work the same as the one you referenced.
In your explaination - your first step is - Move all dual rates to the single switch: ___ Arrow up to PARA - on the 6EX 2.4GHz transmitter, all the dual rates are already on a single switch and there is no PARA function.

Later in your procedure under PMIX, it says :

___ Cursor over to set the amount of the mix. Set it to 100% so they are identical (then adjust as needed to make travels match)
___ Move the master channel stick so the R/U, L/D changes and set the second side of the % also. (in this example, push up elevator)

This also is not possible - when you set the amount to 100%, it is not adjustable my moving the channel stick.
