AOA is on max (150) on ground

Hi there,
after I connected the tubes to the AFS-4500 for the AOA all was as normal, but today it shows 150 and no bars and the voice continuesly says "angle angle push" even if I press audio off. I am not flying yet but wonder what I can do now on the ground to get it back to normal.

Kind Regards
Michael

Send me a picture of your AOA calibration screen.

Issue resolved the tube was blocked.
