Module No. 3554
Measuring Your Heart Rate
While wearing the watch on your wrist, you can use it to perform approximate measurement of your heart rate.
You can use heart rate measurements to monitor your daily health and to make your training more effective.
Important!
For more accurate measurement results, configure your profile settings before using the heart rate measurement function.
Be sure to affix the watch to your wrist before starting a heart rate measurement operation. Starting a measurement operation and then affixing the watch to your wrist may make correct measurement impossible.
