31 000 horizontal brush strokes/minute.
* Sonic vibration in acoustic wave eld
►Bleeding of the gums
When you rst 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 rst
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.

toothbrush will gradually reach the selected speed and
vibration approximately 2 seconds after it starts operating.

• Charging the battery for more than 17 hours will
not damage the main unit.
►Battery runtime on a full charge
Mode Battery runtime
NORMAL
SOFT Approx. 90 minutes
(Use time may vary depending on ambient
temperature and use conditions.)
Notes
• If the charge status lamp ( ) blinks quickly (twice per
second), it may be due to a charging error or because
the main unit is not properly mounted on the charger.
Conrm the recommended temperature and mount
the main unit on the charger properly.
10
English
• 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 rst
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.
Basic usage
Preparation Select the appropriate brush for the
desired use. (See page 12.)
1 Attach the brush head to the
main unit�
• Align the front of the main unit and
the front of the brush head.
1. Ensure that the direction is correct.
• Do not attach the brush head by
twisting it into place. Doing so may
damage the brush head and main
unit.
• The toothbrush shaft will move when a force is
applied. This is required for operation, and is
not a malfunction.
2. Apply a small amount of toothpaste.

head and the main unit (a few mm), but
this is not a malfunction.
2 To avoid spattering of toothpaste, put the
brush head in your mouth and press the
power switch to turn on the main unit�
►Select the desired mode

and “3 back of the teeth”
spending 30 seconds.
Repeat this same procedure for
the other 3 areas.
• By brushing the above 4 parts

experience a tickling or tingling sensation caused by
the sonic vibrations.
The sensation should subside after you use the
toothbrush several more times.
• If you push the brush head too hard, the sound may
change, but this is not an abnormality.
