Hello everyone, I bought two Bally S9000 machines. I got them both to boot up and play with not much trouble. I did have one of them have a Door open B error after bootup. It ended up being the belly door was just out a very little bit after the long trip. I just pushed in on it good and the error went away. The older gentleman that I bought them from I guess had the volume set real low because they were in a real small room. This is the first time I have messed with the S9000 machines. What has to be done to turn the volume up on these. I have searched and have not been able to find anything on adjusting the volume. Is it something simple or is it something more detailed. I'm going to kick myself if it's on the touch screen or something. Thanks
