If the toothbrush handle is dropped, the brush head should be replaced before the next use even if no damage is visible
Replace brush head every 3 months or sooner if brush head becomes worn.
Clean brush head properly after each use (see «Cleaning recommendations» para-graph). Proper cleaning ensures the safe use and functional life of the toothbrush.

Important Information

This toothbrush, charger and pouch (acces-sory) contain NdFeB magnets and generate magnetic fields. If you use a medical device or have an implanted medical device, con-sult with the medical device manufacturer or a physician, if you have questions about safely using your Oral-B iO toothbrush.
Your Oral-B toothbrush can be used with your smartphone (find details under
«Connecting your toothbrush to your Smartphone»). To avoid electromagnetic interference and/or compatibility conflicts, disable Bluetooth® on your toothbrush han-dle (5) before using it in restricted sur-roundings, such as aircrafts or specially marked areas in hospitals.
Disable Bluetooth by entering the «Set-tings» menu on the interactive display (4) -> Bluetooth -> disable. Follow the same procedure to enable Bluetooth again.
Persons with pacemakers should always keep the toothbrush more than 15 centime-ters (six inches) from the pacemaker while turned on. Anytime you suspect interfer-ence is taking place disable Bluetooth.

Noise level: 64 dB (A)
First use
Please wake up your toothbrush by pressing the on/off button (7) and follow the instruc-tions on the interactive display (4) to get started for first time setup.
If not further instructed on the display, you may toggle with the mode button (8) and select with the on/off button (7).
You may change the settings via the «Set-tings» menu (17) at any time.

Charging and Operating

To charge the battery place the toothbrush on the plugged-in charger (6).
The charge level is indicated on the interac-tive display (4). Once it is fully charged the display turns off.
A full charge typically takes 3 hours.
IIf the battery is running low the motor reduces its speed and the Smart Pressure Sensor (3) shortly blinks in red. Once the battery is empty, the motor stops; it will need at least a 5-minute charge for one usage.

Note: In case the battery is empty (display off), charge for at least 30 minutes.

You can always store the handle on the plugged-in charger to maintain it at full charge; a battery overcharge is prevented by the device.

Note: Store handle at room temperature for optimal battery maintenance.
Caution: Do not expose handle to tempera-tures higher than 50°C / 122°F.

Using your toothbrush

Start Brushing
Place the brush head on the handle. A small gap should remain between handle and brush head. Lift the handle off the plugged-in charger
or simply pick it up to wake up the handle
(display turns on). Wet brush head and apply toothpaste. To avoid splashing, guide the brush head to your teeth before switching the handle on by pressing the on/off button.
Note: Display turns off after some time.

You may press the on/off button to activate display again.
Guide the brush head from tooth to tooth. Brush the outsides, the insides and the chew-ing surfaces. Brush all four quadrants of your mouth equally. You may also consult your dentist or dental hygienist about the right technique for you. After Brushing, the display gives you feedback based on your brushing time.

In the first days of using any electric tooth-brush, your gums may bleed slightly. In gen-eral, bleeding should stop after a few days. Should it persist after 2 weeks, please consult your dentist or dental hygienist. If you have sensitive teeth and/or gums, Oral-B recom-mends using the «Sensitive» or «Super Sensi-tive» modes (optional in combination with an Oral-B «Gentle Care» brush head (d)).

Timer
The timer signals with a short stuttering sound at 30-seconds intervals to move to the next quadrant of your mouth. A long stuttering sound indicates the end of the professionally recommended 2-minute brushing time.
The timer memorizes the elapsed brushing time, even when the handle is briefly switched off during brushing. The timer resets if pausing longer than 30 seconds or placing the handle on the plugged-in charger.

Note: During the use of the Oral-B App, the timer may be deactivated for some features.
Note: You may also customize the timer set-tings via Oral-B App.

Smart Pressure Sensor features (a)
Your toothbrush is equipped with a Smart Pressure Sensor (3) that has various function-alities indicated via different colours of light:
White (default) = Operating indicator (choose individual colour via Oral-B App (b)) /

Low pressure indicator

Red = high pressure indicator / low battery indicator
Green = recommended pressure indicator
Blue = Bluetooth pairing indicator
Orange = Error indicator (follow display messages)

Brush with the right pressure indicated with a green light. If too much pressure is applied, it lights up in red reminding you to reduce pres-sure. If the Smart Pressure Sensor illuminates in white (or your pre-selected colour), we recommend applying more pressure.
During high pressure the brush head move-ment will be reduced (in «Daily Clean»,
«Intense Clean» and «Sensitive» modes). Periodically check the operation of the Smart Pressure Sensor by pressing moderately on the brush head during use.

Note: During the use of the Oral-B App, the Smart Pressure Sensor feedback may be inactive for some features.
Note: Smart Pressure Sensor is deactived during «Tongue Clean» mode.

«Intense» – For an extraordinary clean feeling (operated with a higher speed)

When operating the «Tongue Clean» mode, we recommend using a «Gentle Care» brush head (d). You can brush your tongue either with or without toothpaste. Brush the whole area of your tongue systematically in gentle movements. The recommended brushing time is 30 seconds; the motor stops after 30 seconds.

Brush heads

Oral-B offers you a variety of different Oral-B iO brush heads (c/d) that only fit your Oral-B iO toothbrush handle and can be used for tooth-by-tooth precision cleaning.
Most iO Oral-B brush heads feature INDICATOR® bristles to help you monitor brush head replace-ment need. With thorough brushing, twice a day for two minutes, the bristle colour will fade half-way approximately within 3 months, indicating the need to exchange your brush head. If the bristles splay before the colour recedes, you may exert too much pressure on teeth and gums. In general, we recommend replacing the brush head every 3 months.
