How can I tell which heart rate sensor is in use with my A370?
In addition to its internal optical heart rate sensor your A370 can measure heart rate with Polar Bluetooth heart rate sensors H9 and H10. When you pair and connect a compatible hear rate sensor to your A370, it automatically uses the connected sensor to measure your heart rate during training sessions.
You can tell which method is in use before you start a training session:
- Swipe the display to Training and tap it.
- A370 begins to search your heart rate.
- When it's been found, the color of the circle around the heart rate reading indicates which sensor is used. Blue for Bluetooth sensor and green for optical heart rate sensor in the device. You have to wear the Bluetooth sensor correctly in order to use it.
