in the telephone directory. They have a safe reutn policy. Also i was advised by the state of New York about a alert system for mom. but she was not well enough to use it. I would called all the time if she fell and a charge is given. That was too much for me. It all denpends on your mom condtion. It might be a change in medicine with the falls. but that was what was happening to my mom. All the falls and the emergencv phone calls I received. I was always afraid of the basement stairs. this little bit of info may help you out. patrica61
