About a few weeks ago, I was doing a test with my U-MMT horn/strobe “on location” (see Mini Test 65 or any other tests that have been filmed in that location). But when I came back home, I later realized that the tone reference chart that I had was missing. So I went here to find the topic on tone reference charts (since I do believe that there was a topic posted on this matter a while ago), but I had no luck finding it.
So, what I’m saying is that I remember there was a topic about tone reference charts for various multi-tone alarms that I believe Andrew had posted a while ago, and had no luck searching for it recently. Did that topic get deleted or something? :?
