Guys, the cada power supply fails when overloaded, as buwizz goes into defense. But cada, unlike buwizz, does not return to normal operation after that, it stops responding to some of the buttons on the remote control. Empirically found a way to restore it - you just need to reboot it. True, for this you need to disassemble it, and solder the power wires from the board, and immediately solder it back. How to de-energize for a short while. After he begins to work like new. I did this repeatedly with my unit, I came to the conclusion that you should not use it without a differential.
