Polar M71 ti uses multiple methods for determining your safe OwnZone. The primary method is to measure and analyse the heart rate variability and thereby determine the most individual and current parameters.
If your heart rate exceeds the safety limit during the determination, Polar M71 ti picks up your latest OwnZone definition based on heart rate variability. Alternatively, if there is no previous determination in memory, Polar M71 ti will automatically calculate Target Zone limits which are based on your age predicted maximum heart rate. These methods ensure the safest possible exercising zone determination for you.
The method used in defining the exercising Target Zone is indicated after the two beeps as follows:
1.O.Z.V (OwnZone Variability) and the currently determined OwnZone limits appear on the illuminated display.
2.O.Z.L (OwnZone Latest) and your previously determined OwnZone limits appear on the illuminated display.
3.O.Z.A (OwnZone Age) and your

Every time you start the stopwatch and have the OwnZone option on, Polar M71 ti starts finding your OwnZone. You can determine your OwnZone for every exercise session separately. At least it should always be performed when changing exercise environment, exercise mode or if you have abnormal feelings about your physiological state when starting the exercise.
However, you can choose to exercise with the latest OwnZone limits in case you are not willing to start the process of redefining your OwnZone.

2.Press SET/START/STOP. Polar M71 ti starts using your latest determined OwnZone.
O.Z.L and the values for your previously determined OwnZone appear momentarily on the illuminated display.
In case there is no previously determined OwnZone in memory, Polar M71 ti starts using your age predicted exercising limits.
