Body measurement features

  • Automatic age-based target zone – bpm / %

    To help you train safely and effectively, the training computer automatically determines your heart rate target zone limits according to your age-based maximum heart rate (220 minus age). The limits are determined either in beats per minute (bpm) or as a percentage (%) of your maximum heart rate. See also Manual target zone.
  • Average and maximum heart rate of training
  • Heart rate – bpm / %

    Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute (bpm) or as a percentage (%) of your maximum heart rate.
  • HR-based target zones with visual and audible alarm

    You can define your target zones for a training session based on heart rate to help define the right intensity. When you are out of the preset zones, the training computer will give a visual and audible alarm.
  • HRmax (user set)
  • Manual target zone – bpm / %

    This feature enables you to manually enter the target zone that is suitable for your training. You can set the target zone for your training as beats per minute (bpm) or as a percentage of your maximum heart rate.
  • Polar OwnCal® – calorie expenditure

    Polar OwnCal calculates the number of calories burned during training. This feature allows you to track the calories burned during one training session and cumulative calories burned during several training sessions.
  • Polar OwnCode® (5kHz) – coded transmission

    Coded heart rate transmission automatically locks in a code to transmit your heart rate to the training computer. The training computer picks up your heart rate from your transmitter only. Coding prevents interference from other training computers.

Recording features

  • Totals

    Totals includes your training data starting from the last reset enabling you to follow your long-term training.
  • Training files (with summaries) – 10

Training features

  • Graphical target zone indicator
