If you encounter any issues with your smartwatch, please refer to the following common solutions:

|---|---|
| Watch not turning on | Ensure the watch is fully charged. If it still doesn't turn on, try holding the power button for 10-15 seconds. |
| Cannot pair with phone | Ensure Bluetooth is enabled on your phone. Make sure the FitCloudPro app is open and searching for devices. Restart both the watch and your phone, then try pairing again. |
| No notifications received | Check notification permissions in the FitCloudPro app settings on your phone. Ensure the app is running in the background and not being optimized by your phone's battery saving features. |
| Inaccurate health data | Ensure the watch is worn snugly on your wrist (not too tight, not too loose). Clean the sensor on the back of the watch. Remember that data is for reference only. |
