  • In addition to your current heart rate and the maximum and minimum heart rate for that day, display your exercise intensity in the form of your heart rate zone over five different levels.
    Enjoy activities or training without overexerting yourself.

    • * Note that your resting heart rate and maximum heart rate must be set up before your heart rate zones can be displayed.

Heart rate zone alerts

If you set a particular heart rate zone in advance, you will be notified via a display and a vibration when you have exceeded that zone.
This helps to prevent you from overexerting yourself.
