6. Troubleshooting
- Issue: Watch does not power on or charge.
- Solution: Ensure the magnetic charging cable is correctly aligned with the charging points. Try a different USB power source. Allow the watch to charge for at least 30 minutes before attempting to power it on.
- Issue: Cannot pair with smartphone or maintain connection.
- Solution: Verify Bluetooth is enabled on both devices. Ensure the HryFine app is installed and has necessary permissions. Restart both the watch and the phone. If issues persist, unpair the device from your phone's Bluetooth settings and re-attempt pairing through the HryFine app.
- Issue: Inaccurate health or activity data.
