Abstract

A personal response system which automates self testing of help consoles and personal transmitters. Testing is automatically performed at predetermined time intervals by the help console and problems are reported to the response center on a periodic basis. Both the personal transmitter and its battery are tested on a periodic basis and error signals are forwarded to the response center after a predetermined time period. The help console contacts the response center at predetermined time intervals and the failure to contact the response center generates an exception report at the response center.
