Thank you Ron and everyone else. I really appreciate the info. I found the site and listened to the tones. I like them, but I want to get the real MB thing if I can, so TECHS, do you know if this will work??
But I will end up using the sonalert tones if it comes down to it. Thanks again, Ron, you have been a great help.
