Zusammenfassung:A personal emergency response system (PERS) includes a base unit (16) and one or more extension units (20). The base unit includes a speaker (64), a microphone (72), a telephone interface circuit (40), a microcontroller (46), and an autodialer (48). Each extension unit includes a speaker (164), a microphone (172), a telephone interface circuit (140), and a controller (146) without an autodialer. The base unit controller (46) and the extension unit controller (146) are programmed such that in a help mode, the base unit controller and the extension unit controller assume a master/slave relationship.
