For some reason as of yesterday when I arm the alarm itself the remote will sound but the speakers on the car don't do anything.. I have 3 515n's I think mounted in different sections and motion,glass break etc. If the alarm were to go off. I'd be notified by remote but the car will never sound. I don't know if my kid hit a certain button sequence on the remote itself to do this or what. Any assistance would be greatly appreciated, I checked for fuses, lose wire connections, fuses, and I've also d/c all my batteries and left them for around 30 minutes and came back to it. Still no luck, I'm assuming that it could be the pager itself because of the fact that if you hit aux before arm it'll to the silent one instead of the audible noise. I'm not too sure how to get it back though. Because it does it every time....
