Determine Your OwnZone

For background information on Polar OwnZone®, see OwnZone Training.

Select Settings > Exercise > OwnZone.

Find your OwnZone in 1-5 minutes during a warm-up period by cycling or walking/jogging. You should start exercising gently at a light intensity and gradually increase intensity to raise your heart rate.

Redefine your OwnZone:

  • When changing exercise environment or exercise mode.

  • When taking up exercise after more than a week’s break.

  • If you are not completely sure of your physical or mental state – for example, if you are not recovered from previous training, not feeling well, or are stressed.

  • After changing user settings.

Before you start determining your OwnZone, make sure that:

  • Your user settings are correct.

  • The OwnZone function is activated. The cycling computer will automatically determine OwnZone every time you start exercising if the OwnZone function is on.

  1. Wear the heart rate sensor as instructed. Start measurement by pressing OK twice.

  2. When your exercise starts, OZ is displayed and OwnZone determination begins.

Determination of your OwnZone occurs in five stages. If the sound setting is activated, a beep will indicate the end of each stage.

OZ > Cycle at a slow pace for 1 min. Keep your heart rate below 100 bpm/ 50% HRmax during this first stage.

OZ >> Cycle at a normal pace for 1 min. Slowly increase your heart rate by 10 bpm/ 5% HRmax.

OZ >>> Cycle at a brisk pace for 1 min. Increase your heart rate by 10 bpm/ 5% HRmax.

OZ >>>> Cycle at a brisk pace for 1 min. Increase your heart rate by 10bpm/ 5% HRmax.

OZ >>>>> Cycle brisk pace for 1 min. Increase your heart rate by approximately 10 bpm/ 5 % HRmax.

  1. Once you hear two consecutive beeps this means your OwnZone has been determined.

  2. OwnZone Updated and the heart rate zone are then displayed. The zone is displayed in beats per minute (bpm) or as a percentage of maximum heart rate (HR%) or as a percentage of your heart rate reserve (HRR%), depending on your settings.

  3. If OwnZone determination was not successful, your previously determined OwnZone will be used and OwnZone Limits is displayed. If OwnZone has not previously been recorded, age-based limits are automatically applied.

You can now continue with your exercise. Try to keep inside the given heart rate zone to maximize exercise benefits.

Alternatively, to skip OwnZone determination and use the previously determined OwnZone, press OK at any phase of the process.

The elapsed time used for OwnZone determination is included in your recorded exercise time.
