Before cleaning your teeth
The brush head of this sonic vibration toothbrush vibrates at a high speed. 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.
•When in use, the main unit of this toothbrush emits a very weak electric current (ionic current) in the oral cavity.
•Touching the ion panel with your hand when you hold the main unit to brush your teeth causes a very weak electric current (ionic current) to flow between your teeth and the brush head.
a Brush head (negative
electrode)
b Ion panel (positive
electrode)
•The ion lamp on the mechanism that generates the very weak electric current (see figure above) turns on or blinks to indicate whether ionic power is being applied to the teeth.
c Very weak electric current d Mechanism that generates

•You can easily see the lamp status if you use a mirror while brushing.
•Ionic power is not employed with the point brush. (The ion lamp blinks.)
Pressing the power switch
Activates the mechanism that
generates the very weak
electric current, and the ion
lamp blinks on and off.
Putting the brush in your mouth
Passes a very weak electric current in the oral cavity, ionic power is activated and the ion
lamp turns on.
Notes
•Recommended ambient temperature for using is 5 °C – 35 °C (41 °F – 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.
•Do not forcefully turn the brush head with the brush head attached to the main unit. Doing so may cause the brush head or main unit to become damaged.

It is not possible to whiten the color of teeth beyond their original color, yellowing teeth due to aging, or discolored teeth.
► About soft start function (For WHITE mode only)
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 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 notification timer function 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 at each part. Brush the other parts in the same manner, and brush your whole mouth in about 2 minutes.
► About mode storage function
This function stores the previously selected mode of operation, allowing the same mode to be used again. Mode storage is reset if the unit has discharged and has been unused for a long period of time, or if the battery has been completely drained. After charging, the product starts in WHITE mode, however this is not a malfunction.

Tips on usage
5 3
How to apply/move when brushing your teeth
Mode: WHITE/SOFT/SENSITIVE
► For the boundary between the tooth surfaces, or teeth and gums
Place the bristles at a 45˚ angle.
► For the back of the front teeth or misaligned teeth
Brush vertically. Move toothbrush to match the angle of the teeth.
► For the biting surface (back teeth)
Apply from top.
•Place the bristles of the brush gently against your teeth and move the toothbrush slowly. The movement will slow down when the brush head is applied too strong.
•Apply a small amount when using toothpaste.
11
Page 12
How to apply/move when cleaning your tongue
Mode: SOFT
Apply the tongue cleaner so that it barely touches the tongue, and move forward with slight force from the area that becomes dirty. Repeat several times.
•You may injure your tongue if the tongue cleaner is pressed against the tongue too hard.
► To prevent emetic response
Poke your tongue out and apply the brush while you are breathing out.
How to use the point brush
Mode: WHITE/SOFT/SENSITIVE
Use in areas where your teeth are misaligned or in areas that are hard to reach with a standard brush head.
•Use the brush perpendicularly.
•Move the brush gently between your teeth.
•Apply just enough strength so that the tips of the
brush head bristles are lightly touching your teeth.
How to use the ionic two-way silicone brush
Mode: GUM CARE
•Carbon is used in the rubber section, so gripping it firmly may cause a black powder to adhere to your hands, however this is not a safety concern.
•This toothbrush is different to one with a brush head with nylon bristles, as there is no sense of scouring‑type brushing.
•Be careful when using the brush head ‑ forcefully pulling or biting the rubber section may cause it to come off. Do not apply the brush to your teeth. (This
•
can cause the silicone brush to degrade.)
•Select your preferred stiffness from “normal” or “stiff.”
Application to gums/movement
•Use as close as possible to a right angle.
•Use the toothbrush so that the tips of the
silicone brush bristles are lightly touching your gums. Move the brush back and forth gently across your entire gums.
•Recommended usage is once a day, for approximately 2 minutes.
•Use gently at points of concern. (Use for around 10 to 20 seconds at each area.)
