Personal emergency response communication apparatus is a new and useful improvement for pager to access 911 system to call for help (Police, Fire Department and Paramedic). Equipped with a preprogrammed switch to 911 system, a micro computer chip for memory, mini speaker, microphone and an antenna. Upon triggering the emergency 911 switch, an internal preprogrammed system transmits an encoded message to 911 Emergency Response Center in the immediate area. The personal emergency response communication includes at least one communication system, remote communication device, and at least one MSC and PSTN System. In response to a paging message from a paging party, the communications system transmits audible messages corresponding to the paging messages via a communications link. Once connection is completed the "911" number characters will show on the display window of the pager. User can talk on the microphone and listen on the speaker for the emergency operator's response. Audible messages are uniquely possible through forward voice/control channels and reverse voice/control channels,a two-way communication system for real-time interactive conversation. User will be able to disclose nature of the emergency and his/her location;and appropriate action can take place in a few minutes. To end or disconnect transmission, simply turn-off the same switch previously used to activate/start the initial transmission. The right side design of the pager is contoured/rippled for easy grip.
