- Make sure the display on the watch is ON when attempting to bind with the App.
- The watch can't be searched and bound when the battery dies. Therefore, you may check whether the watch has any power left. If not, you may charge it before you retry the search and binding.
- Switch off and then turn on the mobile phone Bluetooth.
- Restart the phone.
Notes: If the previously bound mobile phone is within the Bluetooth range of the watch, the mobile phone will preferentially establish a connection with the previously bound watch.
