Numera Libris is a cellular device. For proper operation, Libris requires adequate cellular coverage. Poor cellular coverage may result in the inability to place a call or automatically detect a fall. Check with your customer service team for known coverage limitations.
As with all location-based services, it may not always be possible to determine your location. Multi-level buildings, parking garages, and even dense urban areas can make it difficult for satellites and cell phone towers to locate your exact location.
In an emergency, please provide your response team with as much information as possible about your location.
