Hey guys,i desperately need some help... after takeoff at about 10000ft an orange button illuminates showing "auto fail" in the overhead. you can also hear a beep tone which stops after a certain amount of time... i would really appreciate to get some help. Best regards, Dominik

Sounds like your auto pressurization has failed, check the Quick Reference Manual.

It definetely has something to do with pressurization system. Make sure both packs are on AUTO and the engine bleeds are open. If they both are off, the aircraft will not pressurize. If the problem don't go away, go to the Quick Reference Handbook.

Make sure Packs are auto, bleeds are on, pressurisation is set to Auto and your desired flight level is set in the pressurisation system.
