Why is this important?
Well, it goes with the other issues about how far the person might be from the base station. If the elderly person has a very soft voice or has a disability that keeps him or her from speaking clearly at a fairly loud volume, then they will need to be close to the base station in order for communication to be effective.
If this is the case, you’ll need to look for a unit that allows communication using the pendant, instead of just through the speakerphone on the base station.
