Troubleshooting
If you encounter any issues with your device, refer to the following common problems and solutions:
- Device not turning on: Ensure the device is fully charged. If it's a new device, charge it for at least 3 hours before first use.
- Device gets hot or doesn't vibrate: Ensure the cleaning head is properly tightened using the provided wrench. The intelligent recognition system only activates vibration when in contact with hard surfaces like teeth, not soft tissues.
- Ineffective plaque removal: Ensure you are using the appropriate cleaning mode for the level of plaque/tartar. Beginners should start with the soft mode and gradually increase intensity as comfortable. Consistent and patient use is key.
