just bought 5 secondhand cmc controlles from ebay

i try to make it work but not everything works. i believe its becouse the guy set it as he wanted cause when i press it does something else.
how do i reset it and make it return to defult?

i cant figure out if all keys work…
any tips for how to reset it? and how to set up the buttons fast?

thank you.

There is no “resetting” or configuring these devices. All setup is done using software. Use the editors that come with them. and read the manuals.

i didnt get any editors. only controllers…

the editors are software or an item?
he sent me just controllers.

they are software you can download from here
