I am commissioning my new system but I cannot connect to the Cerbo GX with my phone. My serial number is HQ2331\* and the instructions on the website say that there is a random pin printed on the back label of the device. I tried the 000000, 0000, 1234 defaults which do not work. I have removed the device and taken a picture of the label but the label does not have a pin. it only lists the part number and serial. There is no … menu either in the app to reset the device. I can’t seem to find a way in the touch interface to set a pin either. How can I connect to this to complete the setup? My other devices all had cards and pins printed on the side of most of them. The only device I can’t see now is my Cerbo GX, but that is the brains of the entire system.

That serial number should have a random pin and details, often also on a label on the box. The other thing to try is wifi connection on your phone by scanning the QR code per Section 7.2 of the manual.
