Ah nice. Always interesting to see how different systems work from airframe to airframe, considering from the pax perspective, how similar much of it looks. But I did find it kinda coincidental that in all my years of flying I'd never heard such an announcement. Then I read a thread on FT about such an announcement on someone's flight and then just a day or two later, I have the same experience.
