I do have a Manual for the Genesis 46 however it's basically an assembly guide. I also have a folded A3 laminated sheet with instructions on How to set correct gear mesh, Shim installation, Genesis 2nd and 3rd speed tuning instruction, How to insert the center diff locker, Genesis 46 helpful hints, Genesis Starting instruction and NX76 Engine Set-up and Tuning Instructions.
However not much about the Airtronics Radio System.

Thanks for your advice will give it a try, let you know the results.
