Functions of Your Toothbrush

Soft start function

To prevent toothpaste from spattering and to get accustomed to the high

speed vibration, the toothbrush will gradually reach the selected speed and

vibration approximately 2 seconds after it starts operating.

This function is only in NORMAL mode.

Introduction

The Sonic Vibration Toothbrush is

an electric toothbrush with sonic vibration* of approximately 31,000 brush strokes/

minute.

* Sonic vibration in acoustic wave field

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.

30-second brushing notification timer function

The toothbrush will pause once at 30-second intervals to indicate the

brushing time.

Pause

The main unit pauses twice at 2-minute intervals then starts again.

GUMCARE mode does not have this function.

Example of brushing sequence

Divide your teeth into 4 parts (upper and lower,

left and right), and brush one part at a time in

order such as “ front of the teeth”, “ biting

plane of the teeth”, and “ back of the teeth”

spending 30 seconds on each.

By brushing the above 4 parts for 30 seconds

each (about 2 minutes), you can evenly brush

your teeth without missing any spots in your

mouth.

English

Sonic vibration toothbrush (ion type)

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.

Pressing the power switch

activates the mechanism

that generates the very weak

electric current, and the ion

lamp

blinks on and off.

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.)

Ion Lamp Q&A P. EN21

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.

When in use, the main unit of this

toothbrush emits a very weak

electric current in the oral cavity.

The combination of the sonic

wave from the linear motor and

the force of ions improve its ability

to remove dental plaque.

The ion lamp turns on or blinks to indicate whether ionic power* is being

applied to the teeth.

* Ion power is a weak electric current passed through the ions in saliva.

Using the Toothbrush

Place the brush head firmly onto the toothbrush shaft.

Place the toothbrush in your mouth.

Press the power switch to turn on the main unit.

Ensure that the direction is correct.

Align the front of the main unit and the front of the

brush head.

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.

There is a small gap between the brush head and the

main unit (a few mm). This is necessary for operation

and is not a malfunction.

To avoid spattering of toothpaste, put the brush head in

your mouth before turning the power on.

Apply a small amount of toothpaste.

Move the brush head with the bristles lightly touching

your teeth.

When first using this appliance, some people may

experience a tickling or tingling sensation caused by the

sonic vibrations.

The sensation should subside after you use the

toothbrush several more times.

A sound may be heard when the brush head is

pressed too strongly against the teeth, but this is not a

malfunction.

Notes

Recommended ambient temperature for using is 5 °C – 35 °C.

Toothbrush may not operate outside recommended temperature range.

Do not put the main unit in contact with hair products, hand creams, etc.

(Doing so may damage the exterior.)

English

Select the mode.

Each time you press the power switch, the mode changes.

(When you turn the power on, the unit is in NORMAL mode.)

Mode Description Brush head

NORMAL Recommended for normal brushing.

a pen so that your hand does not touch

the ion panel.

Please grasp the main unit as shown

in the right figure, so that your hand

comes in contact with the ion panel.

Do not use the brush with toothpaste.

Care for gums

How to apply/move the toothbrush

Gums

90°

Use as close as possible to a right angle.

Use the toothbrush so that the tips

of the silicon brush bristles are lightly

touching your gums. Move the brush

the shape of your gums, there is a risk of

damaging your gums. If you have a concern,

please consult your dentist.

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.)

The light turns

on even though

the toothbrush

is not in my

mouth.

During use, the weak electric current may flow through the

moisture on your hands when you touch the ion panel and the

brush head electrode section (or toothbrush shaft) with your

hand.

When you turn the power on and wash the main unit, the

very weak electric current may flow through the moisture

between the toothbrush shaft and the ion panel.

When you remove the brush head from your mouth just after

brushing without turning the power off, the weak electric

current may flow through the liquid such as saliva on the brush

head and the main unit.
