Testing the dial with red and green
“You have to realize if spirits can manipulate this device it's not like sending a text, it would be difficult, of course you will get random words at times. I've tested this a lot being a paranormal investigator myself and I'd say it does have truth to it. I was able to ping all red dials and I told the spirit to make the bars red, I told it to step back, the bars went back to green. I said step forward and make them red, and it went to solid red for 60 seconds.”
