Factory Reset
You can reset the Rosalind Pro by holding down buttons 1, 2, and 8 while plugging it in. Hold them until they change to the long-press color (about 1 second), release, and then the unit will reset and be back to default configuration.
This restores the IP settings to 10.1.0.20 and resets most configuration settings, but does not clear any of the saved preset data.
