Disper

I have actually accidentally triggered this twice so far.

Basically i used to use Airplay from my iPhone to a wireless Dac which allowed me to play music remotely to my tube stereo.

I turned off 'sound check' (which normally compresses the music to make the volume changes between songs more 'even') because i wanted to maximize sound quality/dynamics.

So I often play music on shuffle and sometimes between songs like classical guitar to modern/synth rock could become quite a volume jump since sound check was not on. I would often have the phone on the floor next to my chair and if there was a big jump in volume i would try to lower it with the volume buttons (because of apartment neighbors).

However since the power button is on the opposite side i somehow accidentally activated the sos when trying to do rapid presses of the volume. When i heard the sos chime, i tried to cancel the emergency that came up on the screen but regardless each time i got a call back from emergency services and i had to give them information about my name and address and tell them it was an accident etc for them to not send a car over.

So just trying to mash the volume buttons triggered this for me.
