The microcomputer is also configured to cause the medical monitor to display an in-service help screen on a display on the medical monitor in response to a detection of a predetermined number of out of range values of the physiological parameter. The microcomputer can also be configured to process a second signal from a second sensor representative of a second parameter and the microcomputer configured to cause the medical monitor to display an in-service help screen on a display on the medical monitor in response to a detection of a predetermined number of out of range values of the second parameter.
