Hello pilots,Just a realtime related question - is there any way to make a dingdong sound to PA speakers, example before some words by captain to the passengers? I know that some airplanes do have it, so maybe 737 has as well.

Hi,Why not try out the ATTEND button on the O/H?Hope it helps,

Well that gives the sound but it actually lights up a led in the cabin on exit signs to announce attendants that flight deck has a call to them. Maybe theres something more specific?
