- Connect the provided Type-C charging cable to the toothbrush and a compatible USB power source (e.g., wall adapter, computer USB port).
- The indicator light on the handle will illuminate to show charging status. A full charge typically takes a few hours.

Attaching the Brush Head

Operating
Brushing Technique
For optimal cleaning, wet the brush head and apply a small amount of toothpaste. Place the brush head against your teeth at a 45-degree angle to the gum line. Move the brush in a gentle circular motion, allowing the sonic vibrations to clean your teeth effectively. Brush for two minutes, ensuring all surfaces of your teeth, gums, and tongue are cleaned.
