Your OnMove 500 features a heart rate monitor with an optical sensor to help you be more efficient during your workout.
To ensure accurate measurement of your heart rate:
- Wear the watch with the dial on the top of your wrist
- The watch should be placed right after the protruding bone, in contact with your skin
- Adjust the strap so that it is firmly tightened without discomfort. The watch should not rotate or move on your wrist.
