1. Start button.
Long press to turn the watch on and off. Once on, a short press turns the screen on or off. Within a menu, press briefly to exit the menu and return to the home screen, or to pause/resume the sport you are performing. It also has a rotary function, allowing you to scroll vertically within the different menus.
NOTE: This button is not removable like some watches. Forcing it out can damage it.
2. Heart rate monitor and oximeter.
These sensors should be placed close to your wrist to measure correctly.
3. Charging connector.
Bring the end of the magnetic charging cable close to this connector to attach it to the watch. Connect the USB end to a USB charging port to charge your device.
