What do Pixhawk tones mean?

I have an IRIS+. Found a list of some controller tones but there are tones I hear that are not in the list. Does anyone know of a complete list of tones?

Are there also tones played through the transmitter controller? Seems like if low battery only comes from the copter and it is out of earshot, then the tone is not much help.

Ok, I’ve been meaning to update all the tones on the wiki. Sorry about the delay.

I don’t think the IRIS transmitter has a speaker in it (I could be wrong - although i fly with an IRIS I use a futaba transmitter). I think the best solution is, if possible, to use Tower running on an Android phone or tablet.
