Changing the ATL setting on Code / Etronix Radio

[qatmix]

Hi All

I have the stick radio version of these sets.

I want to change the ATL value to 100 or 0 but I cannot find it anywhere in the menus! I have the manual and it simply says move the dial to change it. As there is no dial I am stumped! I know it can be changed as I had it changed to allow my hobbywing esc to go into reverse. (The ATL setting confused the double tap reverse). But I reset it and no one seem to remember how to do it.

Help!
