Over the weekend I was having a little get together at my house. You know the usual, beer, food and arcade games and of course pinball. Now my dog wears one of those invisible fence type collars but it is one of the ones that you set the transmitter somewhere and it makes a radius area where the dog can go. Think it uses 2.4 ghz radio waves like a cordless phone does. I have only been collecting for a month now so a month ago I had zero games. Now I got 4, two pinballs and two arcade games. I went to let my dog out the back door which I don't do all the time but never had any issues before. This back door is right where all the games are at as well. He was fine once he walked in the room, however once he started going out the door, his collar started beeping and going off like he was outside his boundaries. Now the poor guy is afraid to even go in that room. Since this never happened before, I can only assume the games were causing some type of interference. Anyone else have anything like this happen. I did have the arcade games on before when I let him out that way, so I can only it's the pinball machines causing it
