This is the worst system I have tried. It corrupt my notification system and can not modify the system. The system goes into alarm extremely loud and can not be modified. I spent alot of money for this system and the Lebre 14 day. I found out they are not compatible. This system is typical to American Medical Services to prophet on human illness. The technical support is the worst I have ever witnessed. I will try another system such as DEXCOM, I see they appear to be better.
