What I learned the first evening with the new mmwafe. It reacts on electric firelighters, but I didn't know why exactly. In flat at this time, and I'm happy about, the only source. Ya, here in Salzburg same, the entrance of a supermarket also about 6400 mikrowatt max., about 1000er peaks but the S&S in a small bag little hidden only passing. But later I will measure more exactly, I try. I love this small safe and sounds, very sensitive, thanks, good work.
