Compro 16016 programming

[What's_nitro?]

Hey guys I'm having similar issues with my 16016. I think MGM changed the software because my controller seems to have only 9 categories (A-I) instead of 10 (A-J). I know this because upon entering the programming mode I can only "ENTER" 8 times before it ends. So there seems to be one category missing from the list. The controller makes the "WRONG VOLTAGE" error beep whenever I turn it on. And whereas I don't know which category is missing I dont know where each category is in the list. So I can't make the correct changes. I have a DX3.0 radio and a Lehner XL2800 running 4s.
