*** Heart Rate function ***
As the watch face does not automatically measure and does not automatically display the HR when installed, pls perform manual action.
To do this, tap on the heart rate display area (Tap to measure in the watch).
As the measurement is WIP, the HR Icon will turn Red and within few seconds, the HR measurement will be displayed.
You can set the watch to measure Heart Rate every 10 min. You can always tap on HR Area to take manual measurements.
