Polar heart rate monitor uses multiple methods for determining your OwnZone. The OwnZone determination is based on measuring and analysing the heart rate variability during graded exercise.
If your heart rate exceeds the safety limit during the determination, Polar heart rate monitor picks up your latest OwnZone definition based on heart rate variability.
Alternatively, if there is no previous determination in memory, OwnZone limits, which are based on your age predicted maximum heart rate, will be used. These methods ensure that the safest possible exercise zone is determined for you.
The method used in defining the OwnZone is indicated after the two beeps as follows:
1. OZ.V (OwnZone Variability) and the currently determined OwnZone limits appear on the illuminated display.
2. OZ.L (OwnZone Latest) and your previously determined OwnZone limits appear on the illuminated display.

3. OZ.A (OwnZone Age) and your age-predicted heart rate limits appear on the illuminated display.
You will also see which OwnZone level you have selected to use:
BASIC (OwnZone Basic for allround exercising)
HIGH (OwnZone High for exercising at moderate intensity)
LOW (OwnZone Low for exercising at light to moderate intensity)

Every time you start the stopwatch and have the OwnZone option on, the Polar heart rate monitor 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.
1. Start the heart rate measurement and stopwatch as usual.
OZ appears on the display.
2. Press OK. Polar heart rate monitor starts using your latest determined OwnZone.
OZ.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 heart rate monitor starts using your age predicted exercising limits.
OZ.A and your age-predicted heart rate limits appear on the illuminated display.
