Operating
1. Powering On/Off and Mode Selection
Press the power button to turn the toothbrush on. To switch between the three smart modes (Daily Clean, Whiten, Sensitive), press the mode button located below the power button. The selected mode will be indicated by a light on the handle.
2. Brushing Technique
Wet the brush head and apply a small amount of toothpaste. Place the brush head on your teeth, starting with the outer surfaces. Guide the brush head slowly from tooth to tooth, allowing the oscillating-rotating and micro-vibrating bristles to clean each tooth surface. Do not scrub.
3. Smart Pressure Sensor
The built-in pressure sensor indicates optimal cleaning pressure and warns of over-pressure. The light ring will change color to provide real-time feedback:
- Green: Optimal pressure.
- Red: Too much pressure. Reduce force to avoid harming gums and teeth.
- White: Too little pressure. Apply slightly more force for effective cleaning.
4. Two-Minute Timer
The toothbrush features a two-minute timer with four 30-second intervals. It will briefly pause to signal when it's time to move to the next quadrant of your mouth, ensuring a thorough and consistent clean.
Maintenance
1. Cleaning the Toothbrush
After each use, rinse the brush head thoroughly under running water with the handle switched on. Remove the brush head and rinse both the brush head and the handle separately. Wipe the handle with a damp cloth. Do not immerse the charger in water.
2. Replacing Brush Heads
Dentists recommend replacing your brush head every 3 months, or sooner if the bristles are splayed or worn. To replace, simply pull the old brush head off the handle and push a new one on until it clicks.
