5.3 Charging

Recharge the toothbrush when the battery indicator shows low power. Use the provided USB Type-C cable. The long battery life minimizes the frequency of charging.

5.4 UV Sterilization Travel Case

The travel case includes a UV sterilization function to keep your brush head clean. Place the brush head into the designated slot in the case. Close the case to activate the UV light, which helps to eliminate bacteria.

6. Troubleshooting

6.1 Toothbrush Not Turning On or Charging

• Ensure the toothbrush is fully charged. Connect it to a power source and check if the charging indicator light is active.
• Verify that the charging cable and adapter are working correctly. Try a different cable or adapter if available.

6.2 Weak or No Vibration

• Check the battery level. A low battery can result in weaker vibrations.
• Ensure the brush head is securely attached. A loose brush head can affect vibration transfer.
• If using the app, verify that the intensity setting is not set to the lowest level.

6.3 App Connectivity Issues

• Ensure Bluetooth is enabled on your smartphone and the toothbrush is within range.
• Restart both your smartphone and the toothbrush.
