To connect your device, you need to connect the calibration app. Once the connection is successful, the watch will automatically synchronize the time. To get started, turn on the Bluetooth switch on your mobile phone and enter the app device module settings. Click on the "Settings" icon to enter the automatic search list and find the watch device to connect with it. If the connection is successful, turn on the system Bluetooth synchronization switch. (Note: Before using the Bluetooth function, make sure the system Bluetooth synchronization switch is turned on). The app will automatically save the Bluetooth address of the bracelet. When the app is opened or running in the background, it will automatically search and connect to the bracelet. For Android phones, make sure to allow all notification permissions such as reading contact information and allowing the app to run in the background in the phone settings.

To connect via Bluetooth, first turn on the Bluetooth switch on the watch and smartphone. Then, enter the Bluetooth notification menu and click to automatically search for nearby Bluetooth-enabled devices. Find the phone device model and pair it with the watch. After successful pairing, the Bluetooth icon in the status bar of the watch will display green, indicating that the watch and mobile phone have successfully searched for devices. (Via watch search for equipment, there is vibration and ringing on the mobile phone end; through cell phone finding device, there is vibration and ringing on the watch end). You can search, add, and delete Bluetooth devices, and view the name and address of the device's Bluetooth in About Phone.
