Abstract:
A participant response system (50) comprises at least one host computer (52) and a plurality of battery-powered remote units (62) communicating wirelessly with the host computer (52). Each remote unit (62) executes a diagnostic routine in response to a received status request broadcast by the host computer (52) to detect the status thereof. Any remote unit (62) that detects an unhealthy state, returns health information to the host computer (52).
