8 CHECK PATIENT
PROBE Indicates the patient probe is sensing an abnormal patient temperature (below 32°C [89.6°F] or above
45°C [113°F]). An audible alarm accompanies this alert.
WARNING: It may indicate the patient probe has become dislodged, an incorrect probe is being
used, or a probe has become defective.
