Hi, today when I turned on my Profi it made a screaming noise and the startup gong gong was heard in the background. After that the screaming sound went over to a kind of speaker earth fault sound not so loud.
After changing to german language its OK, when selecting english again and turn it off and on the same sound is there. Tried to installed firmware 3.56 again but no luck, same screaming sound. The lates model I made yesterday had got a cryptic name and a symbol that I have never seen before.
It also came up with a warning "stabthrottlehigh, save when pressing any key". After that no buttons responded. Had to do a new firmware update before this disapeared.
Now I made a new model again and set it to german language because we have a flight meeting this weekend and I think its safe to use it this way?
