yes, the combination is Hw once Sw for 20 sec, but? i will loose and the "out of the box" experience i think. (correct me if i'm wrong, other DMPS-300-C that is not locked, when i connect with toolbox, i have a graphical interface where i can select sources and adjust the sound. i'm afraid if i reset the locked one, i will loose also this, which i dont have the files to install.
