I made a testflight in FL430 - just the same. But now I'm a little smarter: - I turned on Anti Ice to see the CAS Messages. - I found out that the caution sound comes when the message "CAB DELTA-P FAIL" appears. (btw - shouldn't a CAS Message pop up for the Cab Delta-P fail??!!) - But this warning only appears in high FL an only every 30 - 60 sec. FL430 / Cab Alt 8300 ft / DELTA-P 8.5 PSI / LFE 1600 FT / OXY 1850 PSI <-- everything looks normal

Hi, I got an anoying problem I can't solve - maybe somebody had the same and can help me... At FL450 (and only FL450) I hear a "Bing-Sound" every few seconds (about 30 sec). If I descend to FL430 for example the anoying "Bing" is gone. So I thought that must have something to do with the cabin altitude. But everything is green - and even if I change cabin alt to Manuel and decrease cabin alt the "bing-sound" (kinda like the seatbelt sign remains...) I tried every knob - I just can't turn it off. And all systems are green (no yellow or red)... Would be great if somebody knows the answer ;-)
