Quoted from Radius:Here is 13 seconds of video with the startup sounds, as well as how it doesn't go into attract mode until I push SW2 for the memory test. The coin door is open for the memory test to work.

Yea that short small beep on power on and when you hit SW2 is what you have to worry about. One time my game started with that beep and no music. But it still had sounds. For me some reason resetting the game actually fixed it. Looks like this is not the case with yours
