How to do a soft reset?

hi,

i am sure i am simply to dumb, but how do i do a soft reset with the fenix 6?

with my fenix 5 i had to press and hold the light button and wait for the watch to turn off. on the fenix 6 the emergency alarm starts when holding the light button and i do not find a way to disable the emergency alarm. i am just asking because it seemed to be quite helpful to do a soft reset on a fenix from time to time - at least after a fw update.

thanks
