WARNING!
The time of whistle calculation is based on the ECB clock and may not correspond to the tablet clock. Use the ECB clock
when comparing time of whistle to the current time.
The actual time to whistle may be less than the time to whistle displayed. The actual time of whistle may be earlier than
the time displayed. The calculated time displayed is based on the continuation of the average breathing rate over the
last 3 minutes. Increases in breathing rate can decrease the remaining time more than expected. Use the time to whistle
and time of whistle displays as general guides only.
Failure to follow these warnings can result in serious personal injury or death.
