Adat -du- error for loooong time

[Luzer]

Hi I have an Adat blackface and it have shown the "bad enviroment" message -du- for many hours. It says everywhere that you only should have the adat on for a couple of hours and it will fix itself...but it must be something wrong with the sensor because so long time like this it shouldnt take. Anyone have any tips, can u fix this on your own or is it "fucked up" for good
