Fault Messages

RespSense has built-in self-diagnostics for detection of fault conditions. Detected fault
conditions are presented as messages on the touch panel display. The fault conditions are either
operator- or system-generated. The table below lists common messages, descriptions, and
advice on actions to take.
If the problem persists, contact Nonin Technical Service.
