For averaging modes of less than 14 seconds, the Radical indicates saturation and pulse

rate alarms within 3 seconds of when the alarm condition is met. For averaging modes of

14 and 16 seconds, the Radical indicates saturation and pulse rate alarms within 10

seconds of when the alarm condition is met. Saturation changes of greater than 5% are

indicated immediately, irrespective of averaging time. The Radical visually indicates an

alarm by flashing the measured value and the alarm limits. Alarms are audibly indicated

according to system configuration.
