Review on Wireless Nurse Alert System with 2 Portable Pagers for Elderly Care by Paty Fernandez

The review asked about the volume control. I still don't understand how to control the volume. It's loud enough to wake me up when my mom needs me from another room at night. My mother calls it "Bee Boo". She wears a cord around her neck and calls me when she feels like she's falling (or when she loses the remote control for the eighteenth time ;) ). May not fit through exterior walls. I tried going to the porch which is only 2 rooms from her seat and she tried to call me for a test but she didn't get the page.
