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.
Brush the other parts in the same
manner, and brush your whole mouth in
about 2 minutes.

►Strong pressure prevention function
Pressing the brush bristles too hard against your teeth will
activate this feature, causing the intensity of the vibration to be
weakened automatically as a safeguard against excessive
pressure.
►Precaution
•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.
•Recommended ambient temperature for using is 5 - 35 °C
(41 - 95 °F).
•Do not allow hair products (e.g., gel or oil) or hand lotion to
come in contact with the unit as they may damage its surface.
