Introduction
►For your personal dental care
Thank you for purchasing the Sonic Vibration Toothbrush.
The Sonic Vibration Toothbrush is a new kind of electric
toothbrush designed for those who wish to keep their teeth
clean and healthy. This appliance will enable you to maintain
good dental hygiene, which is as important as other forms of
personal hygiene.
►Sonic Vibration Toothbrush Technology
The Sonic Vibration Toothbrush incorporates the innovative
“linear motor” technology that uses magnetic attraction and
repulsion to provide outstanding performance. The brush’s
31,000 horizontal strokes per minute help remove plaque gently
yet effectively.
►Before use
This high-speed, vibrating, electric toothbrush is different from
conventional electric toothbrushes.
Therefore:
•You only need to lightly press the bristles against your teeth for
brushing.
•When first using this appliance, some may experience a
tickling or tingling sensation caused by the high-speed
vibrations. The sensation should subside after you use the
toothbrush several more times.
Cautions regarding use
•Be sure to switch off the appliance and remove the plug from a
household outlet before performing any maintenance. Failure to
do so may result in electric shock.
•Cleaning and user maintenance should not be made by children.
•Keep the appliance away from children.
•Do not use the charger in the bath. Doing so may result in
electric shock.
•Do not touch or pull out the plug with wet hands. Doing so may
result in electric shock.
•If the power cord of the charger is damaged, the entire charger
should be discarded. The charger should be replaced.
•Do not wrap the power cord around the charger.
•Always ensure the appliance is operated on an electric power
source matched to its rated voltage. Failure to do so may result in
fire or electric shock.
•Clean the plug periodically so that dust does not accumulate in it.
Such dust buildup may trap moisture over time and reduce the
effectiveness of the insulation, thus resulting in overheating and
fire.
•Do not modify, disassemble, or repair the appliance at any time
except when disposing of it. Doing so may result in fire, electric
shock, and/or burns.
•Do not place any metal objects, such as coins and clips, on the
charger. Doing so may cause the objects to heat up, resulting in
burns.

brushing.
•Turn off the main unit before removing it from your mouth to
prevent foam from spattering.
►Brushing duration notification timer
The timer will signal once at 30-second intervals to indicate the
brushing time for each part of your mouth. It will signal twice at
2-minute intervals to indicate the recommended total brushing
time.
•It is important to brush each area in the same sequence and
with the same amount of time, every time you brush, to
uniformly brush and clean your teeth.
Use the 30 second brushing duration notification timer wisely
so there will be no missed spot in your mouth.
•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.
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.
