enabled in Manual Defib mode using the Alarm Pause button. Alarm settings for Heart Rate (HR) and
VTACH are as configured but may be changed during operation for the current patient incident. The
setting for PVC Rate Limit may only be changed in response to a PVC Rate alarm condition. Settings
for other HR and arrhythmia alarms may not be changed.
