  • Sonic vibration in the acoustic wave range

• About soft start function
  The product will gradually reach the selected speed and vibration approximately 2 seconds after it starts operating. This function helps to prevent toothpaste from spattering and get accustomed to the high speed vibration.

• About the 30-second brushing notification timer function

The toothbrush will pause once at 30-second intervals to indicate the brushing time. The toothbrush pauses twice at 2-minute intervals then starts again.

• Divide your teeth into 4 parts (upper and lower, left and right), and brush one part in order such as “1 front of the teeth”, “2 biting plane of the teeth”, and “3 back of the teeth” spending 30 seconds.
