Sonic vibration in acoustic wave field

Bleeding of the gums
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 periodontal disease. In this case, stop using the toothbrush and consult your dentist.

Recommended ambient temperature for charging is 5 °C – 35 °C. The battery may not charge properly or not at all under extreme low or high temperatures.
The charging time may vary when using for the first time, or when it has not been in use for more than 6 months. Also, the charge status lamp ( ) may not glow for a few minutes after charging starts, but it will glow if charging continues.
