- heart rate in real time
- average heart rate in real time
- heart rate in graph form
- calories burned during exercise
- guidance to exercise within defined heart rate limits
- Peak Training Effect
Using a heart rate belt enables the following additional information after exercise:
- calories burned during exercise
- average heart rate
- peak heart rate
- recovery time
Troubleshooting: No heart rate signal
If you lose the heart rate signal, try the following:
- Check that you are wearing the heart rate belt correctly (see Putting on heart rate belt ).
- Check that the electrode areas of the heart rate belt are moist.
- Replace the battery of the heart rate belt, if problems persist.
- Re-pair your heart rate belt with the device (see Pairing POD/heart rate belt ).
- Machine-wash the textile strap of the heart rate belt regularly.
Putting on heart rate belt
NOTE:
Suunto Ambit2 S is compatible with Suunto ANT Comfort Belt.
Adjust the strap length so that the heart rate belt is tight but still comfortable. Moisten the contact areas with water or gel and put on the heart rate belt. Ensure the heart rate belt is centered on your chest and the red arrow is pointing up.

WARNING:
People who have a pacemaker, defibrillator, or other implanted electronic device use the hear rate belt at their own risk. Before starting the initial use of the heart rate belt, we recommend an exercise test under a doctor’s supervision. This ensures the safety and reliability of the pacemaker and heart rate belt when being used simultaneously. Exercise may include some risk, especially for those who have been inactive. We strongly advise you to consult your doctor prior to beginning a regular exercise program.
NOTE:
Suunto Ambit2 S cannot receive the heart rate belt signal under water.
TIP:
Machine-wash the heart rate belt regularly after use to avoid unpleasant odor and to ensure good data quality and functionality. Only wash the textile strap.
Suunto Ambit2 S supports ANT+
TM
compatible heart rate belts and certain PODs. Visit www.thisisant.com/directory for a list of compatible ANT+ products.
