- Press the power button once to turn on the toothbrush. It will start in the last used mode.
- Press the power button repeatedly to cycle through the 5 modes.
- To turn off the toothbrush, press and hold the power button for 2 seconds, or cycle through all modes until it turns off automatically.
2. Brushing Technique
Apply a small amount of toothpaste to the brush head. Place the bristles against your teeth at a slight angle towards the gum line. Gently move the brush across your teeth, allowing the sonic vibrations to clean effectively. Do not scrub vigorously.

3. Smart Timer and Quad-Pacer
The toothbrush includes a built-in smart timer and quad-pacer to ensure optimal brushing habits:
- The 2-minute smart timer automatically turns off the toothbrush after the dentist-recommended brushing time.
- The 30-second interval reminder (quad-pacer) gently pauses or changes vibration intensity every 30 seconds, signaling you to move to the next quadrant of your mouth. This ensures thorough cleaning of all four sections of your mouth.

Maintenance
1. Cleaning the Toothbrush
- After each use, rinse the brush head thoroughly under running water while the toothbrush is briefly turned on to remove any remaining toothpaste or debris.
- Turn off the toothbrush and remove the brush head.
- Rinse the brush head and the metal shaft area of the handle separately under running water.
- Wipe the handle with a soft, damp cloth. Do not use abrasive cleaners or harsh chemicals.
- Ensure all parts are dry before storing.
The toothbrush handle is IPX8 waterproof, allowing for safe rinsing under water.
2. Replacing Brush Heads
Dentists recommend replacing brush heads every 3 months, or sooner if the bristles become frayed or worn. To replace:
- Grip the brush head firmly and pull it straight off the handle.
- Align a new brush head with the metal shaft and push it down until it clicks into place.
Note: The package includes 10 replacement brush heads, providing a supply for approximately 30 months.
