• During charging the on/off button is blinking white. Once it is fully charged the indicator light turns off. A full charge typically takes 16 hours.
• If the battery is running low the low charge indicator (10) blinks in red. Once the battery is empty, the motor stops. To charge the battery please put the brush on the charger.
• The toothbrush can be stored on the plugged-in charger to maintain it at full charge; a battery overcharge is prevented by the device. However, for environmental purposes we recommend to keep charger in the power socket during charging only.
• The toothbrush switches off when exceeding the outside operating limits and/or standard battery current. To enable operation the toothbrush needs to be put on the charger.

Caution: This toothbrush contains a Li-Ion battery. Do not expose toothbrush to temperatures higher than 50°C / 122°F.
Note: Store the toothbrush at room temperature for optimal battery maintenance.
Start Brushing
Place the brush head (1) on the handle (6). A small gap should remain between handle and brush head. Wet brush head and apply toothpaste. To avoid splashing, put the brush head into your mouth before switching the toothbrush on by pressing the on/off button (8). Guide the brush head from tooth to tooth. Brush the outsides, the insides and the chewing surfaces. Brush all four quadrants of your mouth equally. You may also consult your dentist or dental hygienist about the right technique for you.In the first days of using any electric toothbrush, your gums may bleed slightly. In general, 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 recommends using the «Sensitive» or «Super Sensitive» modes (optional in combination with an Oral-B «Gentle Care» brush head (g)). Availability of modes may vary depending on model purchased.
Timer
The timer signals with a short stuttering sound in 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 toothbrush is briefly switched off during brushing. The timer resets if pausing longer than 30 seconds or placing the toothbrush on the plugged-in charger.
Brushing reward illumination
The completion of a 2-minutes brushing event will be rewarded with a colorful light ring illumination (b).
Note: You may also customize the timer settings via Oral-B App.

Smart Pressure Sensor/ Light Ring (a)
Your toothbrush is equipped with a Smart Pressure Sensor (3) that has various functionalities indicated via different colors of light (a):

• White = Low pressure indicator/default setting
• Green = optimal pressure indicator
• Red = high-pressure indicator

Brushing with the recommended pressure is indicated via a green light. If too much pressure is applied, a red light reminds you to reduce pressure. If the Smart Pressure Sensor illuminates in white (or your pre-selected color), we recommend applying more pressure. When high pressure is applied the brush head movement will be reduced (in «Daily Clean», «Intense» and «Sensitive» modes). Periodically check the operation of the Smart Pressure Sensor by pressing moderately on the brush head during use.
Note: You can replace the white default light ring color with a choice of individual colors via the Oral-B App.

Brushing modes (depending on model)

Your toothbrush offers different brushing modes:

• «Daily Clean» – Standard mode for daily cleaning
• «Intense» – For an extraordinarily clean feeling (operated with a higher speed)
• «Sensitive» – Gentle, yet thorough cleaning for sensitive areas
• «Super Sensitive» – Super gentle cleaning for extra sensitive areas
• «Whiten» – Polishing for occasional or everyday use
• «Tongue Clean» – Tongue cleaning for occasional or everyday use
• «Gum Care» – Gentle massage of gums

Note: The sequence and availability of brushing modes may vary depending on the model purchased.

When operating the «Tongue Clean» mode, we recommend using a «Gentle Care» brush head (g). 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.

Mode setting:
For first use, the toothbrush starts with the first mode illustrated on the package of your purchased model. To switch to another mode, successively press the mode button (9). You may change the modes during the brushing event. The toothbrush automatically starts in the mode selected last.
Note: You may also customize mode settings via Oral-B App.
Brush heads
Oral-B offers you a variety of different Oral-B iO brush heads (f/g/h) that only fit your Oral-B iO toothbrush handle. These unique brush heads are dentist-inspired to leave your mouth feeling clean and refreshed.
When to exchange brush head
Some iO Oral-B brush heads feature INDICATOR® bristles to help you monitor brush head replacement need. With thorough brushing, twice a day for two minutes, the bristle color will fade halfway approximately within 3 months, indicating the need to exchange your brush head. If the bristles splay before the color recedes, you may be exerting too much pressure on teeth and gums. In general, we recommend replacing the brush head every 3 months.
Brush Replacement Reminder
The toothbrush is equipped with a «Brush Replacement Reminder» indicating the need to exchange the brush head approximately after 3 months when used twice per day. A yellow light – accompanied by a vibration signal – will illuminate in the mode button (11). To reset the «Brush Replacement Reminder» hold the mode button pressed for 2 seconds. A vibration and illumination signal confirms the reset. If no action is taken, an automatic reset will happen after several days. may appear orange

Information

Bluetooth® indicator
Although all indicated functions on the Bluetooth device are supported, Oral-B does not ensure 100% reliability in connection, and feature operation consistency. Operation performance and connection reliability are direct consequences of each individual Bluetooth device, software version, as well as the operating system of those Bluetooth devices and company security regulations implemented on the device. Oral-B adheres to and strictly implements the Bluetooth standard by which Bluetooth devices can communicate and function in Oral-B toothbrushes. However, if device manufacturers fail to implement this standard, Bluetooth compatibility and features will be further compromised and the user may experience functional and feature related issues. Please note that the software on the Bluetooth device can significantly affect compatibility and operation.

Warranty replacement brush heads
Oral-B warranty will be voided if electric rechargeable toothbrush damage is found to be attributed to the use of non-Oral-B replacement brush heads. Oral-B does not recommend the use of non-Oral-B replacement brush heads.
