Before cleaning your teeth

The Sonic Vibration Toothbrush is an electric toothbrush with sonic vibration of approximately 31 000 brush strokes/minute. Sonic vibration in acoustic wave field
When you first begin using the toothbrush, you may experience slight bleeding of the gums even though your gums may be healthy. This is because your gums are receiving stimulation by the toothbrush for the first time. The bleeding should stop after one or two weeks of use. Bleeding that persists for more than two weeks may be indication of an abnormal condition of your gums, such as pyorrhea. In this case, stop using the toothbrush and consult your dentist.

• About soft start function (For NORMAL mode only)
  To prevent toothpaste from spattering and to get accustomed to the high speed vibration, the toothbrush will gradually reach the selected speed and vibration approximately 2 seconds after it starts operating.

• About the 30-second brushing notification timer function The toothbrush will pause once at 30-second intervals to indicate the brushing time. The main unit 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. By brushing the above 4 parts for 30 seconds each (about 2 minutes), you can evenly brush your teeth without missing any spots in your mouth.
    

Using the toothbrush

The recommended operating temperature of electric toothbrush is 0 °C or higher. If the indoor temperature is below the recommended temperature, the electric toothbrush may stop operating.

• Do not put the main unit in contact with hair products, hand creams, etc.
  Doing so may damage the exterior.

1. Firmly install the brush head onto the brush shaft.

   • Insert the brush head into the brush shaft, with its line aligned to the installation mark of the main unit. (If the line is not aligned, the brush head and main unit may malfunction.)

   • Rotate the brush head to align its line to the fixing position mark of the brush shaft. Do not rotate tightly. (Otherwise, it may cause breakage and deformation to the brush shaft and the brush head.)
     

2. Place toothbrush in your mouth.

   • To avoid toothpaste foam from splashing, use a small amount of regular toothpaste. Before turning on the power switch, put the brush head in your mouth.

3. Press the power switch and choose a mode.
   

   • Some first-time users probably will have sense of itching and pricking because of such sound wave vibration, but after several times of use, such sense will disappear.
   • Every time the power switch is turned on, the mode changes.
     (Each time you press the power switch, the appliance enters NORMAL mode.)
