Your radio has 3 model memory, and each model memory is saved with different settings. And ofcourse 3 models can be stored in your radio and you can fly all your 3 planes with one radio. You must assign model name on your radio as well, as I have 2 model memory radio its JR XF421EX, it came with Hangar 9's combo P51 Mustang PTS. Model one is for my simulator and model 2 is for my plane. In order to switch from model you have to turn on the power switch as well as 2 right buttons on the radio one is for scrolling other is for increasing decreasing simultaneously.

As you found in your manual as well, I hope it would help
