1. Safety Instructions
Please read this manual carefully before use, and retain it for future reference.
When using the toothbrush for the first time, it is common for the gums to experience itching or slight bleeding, which can be attributed to the fact that your gums have not yet adapted to the efficient cleaning of an electric toothbrush. It is recommended to start with the gentle mode. These conditions will typically be resolved within a period of one to two weeks. In the event that they persist for more than two weeks, please stop using the toothbrush immediately and seek medical assistance.

3. Setup
3.1 Installing the Toothbrush Head
Keep the bristle direction of the toothbrush head in the same direction as the front of the toothbrush handle. Align downwards to install the toothbrush head on the handle, and make sure there is a slight gap (0.4-1mm) between the toothbrush head and the handle. This gap is designed to prevent the toothbrush head from colliding with the handle during high-frequency vibration, so as to generate more power from the motor.

The toothbrush's display can be set to English for easier use. Follow these steps:
- Turn on the toothbrush.
- If the display is in Chinese, press and hold the power button for three seconds to enter the settings interface.

4.4 Healthy Brushing Technique
For better brushing effect, it is recommended to use the Bass brushing method, gently moving the toothbrush with the bristles positioned at a 45° angle towards the gum line. The toothbrush pauses briefly every 30 seconds to prompt the user to change the brushing area.

4.5 Intelligent Interaction Interface
The system's built-in algorithm analyzes recent brushing behavior. The display shows information like near-term dental plaque risk, last brushing coverage, and recent brushing pressure.

Missed Area Reminder: The display provides feedback on the current brushing situation through missed area identification after brushing is paused or completed. Cleaned areas are displayed in white and missed areas in orange. You can achieve better coverage by continuing to brush the orange areas. The duration of supplemental brushing varies depending on the areas missed. Once all missed areas are brushed, the toothbrush will automatically pause and display the brushing results.

Brushing Result Display: The display shows brushing coverage, evaluation, and duration when brushing is paused or completed.
Lift to Wake Screen Feedback: The toothbrush has a built-in algorithm model that analyzes recent brushing behavior. When lifted, the screen awakens, providing timely feedback on brushing habits.

Note: It takes about six hours to get the toothbrush fully charged once its battery is depleted.
5.3 Moisture Detection of Charging Port
When connecting the charging cable to the electric toothbrush, if the display shows that the charging port is damp, it indicates the presence of liquid at the charging port. Please ensure the charging port is dry before charging, as it poses a risk of short-circuiting if wet.

- Unplug the charging cable.
- Keep the charging port downwards and shake gently to drain excess liquid.
- Place the toothbrush and the charging cable in a dry and well-ventilated place for air drying. Once the toothbrush is completely dry, try to recharge it. If the display still shows that the charging port is damp, it is recommended to extend the drying period until normal charging resumes.
CAUTION: Please do not use paper towels, cotton swabs, etc. to dry the charging port to avoid foreign objects from entering.
