Note: I have a smart memory function mode, this mode will be memorized after 10 seconds is selected, and the memory mode will be directly activated when the machine is turned on again.

SMILE EVERY DAY!

1. Set the toothbrush head tightly on the brush head shaft as shown in the drawing. There is about a 0.5mm-1mm gap between the brush head and the handle, which is necessary for the normal vibration of the toothbrush head

2. Apply the proper amount of toothpaste to the wet brush head. Tips: To prevent toothpaste splashing, put the brush head in your mouth before turning on the toothbrush.

3. Place the brush head gently on the teeth, and move the toothbrush slowly at 45 degrees from the bristles to the gums.

4. The dentist recommends that you brush your teeth for 2 minutes each time. There will be a short pause every 30 seconds to remind you that you should clean the four areas of the mouth in a balanced manner to achieve the best cleaning effect. After brushing your teeth in 2 minutes, all the lights go out.

5. After brushing your teeth, please rinse the toothbrush with water, wash the bristles, and brush the head after each use, spin dry, and air dry.

I ALSO NEED YOU TO BE GENTLE WITH ME

• Cleaning brush head

  • After each use, clean the brush head and let it air dry.
  • Do not pull the bristles, which may cause deformation and fall off.

• Cleaning the body of the toothbrush

  • Remove the brush head regularly and rinse the metal shaft and toothbrush body with water, wipe it with a soft cloth, and place it in a suitable position
  • Do not put it into the water for a long time
  • Do not use water higher than 40℃ or acidic cleaning fluid to clean it
• • The dentist recommends changing the brush head every three months
  • If the brush head has been used continuously for three months, or if you find hair loss, bifurcation, etc., please replace it with a new exclusive brush head to avoid damaging your gums and teeth

• Brushing strength

  • In the process of using the toothbrush, do not press hard, keep the bristles in contact with the tooth surface, and move slowly

CHARGING

I’M HUNGRY, PLEASE CHARGE ME

• Before using it for the first time, please charge the main unit first. When charging, use your fingers to pull off the sealing cover at the bottom of the body.

• After opening the bottom sealing cover, there is a charging port at the bottom of the fuselage. Connect the USB cable to charge.

• During use, when the power indicator on the handle flashes red, it indicates that the battery power is close to the low power threshold. Please charge the electric toothbrush as soon as possible to avoid over-discharge of the built-in battery and cause malfunction.

• When charging, the battery indicator on the handle flashes red, indicating that it is charging, when the indicator is steady green, it indicates that the battery is fully charged

Note: You must protect me. When charging, you must use a 5V adapter or a USB port on the computer to charge, and you cannot use an adapter higher than 5V to charge!
