Universal remote control code URC22B

Good evening

Here’s what I found for performing an automatic code search, though it might not work...

1. Turn on the device you want to control.
2. Press and hold the SET button, then simultaneously press the POWER button for more than 3 seconds, and the Auto search will start.
3. Press any button to finish.

No further explanations, particularly regarding the duration of the search, which could probably take several minutes.
