Using the brush: Wet the brush head and put toothpaste on the bristles. Turn on the brush. Brush your teeth for 2 minutes, cleaning them first on the outside, then on the inside, and finally on the top surface. Start with the teeth at the bottom of your mouth, spending the first 30 seconds on one half and the next 30 seconds on the other. Continue in the same way with the teeth in the upper part of the mouth. The professional timer will alert you with an audible signal every 30 seconds. If you press too hard on your teeth while brushing, a special sensor will slow down the speed of the brush. When finished, rinse the cleaning head under running water and dry it. When the blue color of the indicator bristles fades by half, you need to replace the cleaning head. Charging the battery: The brush is designed for use in the bathroom.
