pressing the on/off button (3)), charge at
least for 30 minutes.
•
The charge level is indicated on the
charge level display (8). Flashing lights
indicate that the battery is charging (pic-
ture B); once it is fully charged, the lights
turn off. A full charge typically takes
12 hours and enables at least 2 weeks of
regular brushing (twice a day, 2 minutes).
Note: At a very low charge level, the lights
might not flash immediately; it can take up
to 30 minutes.
•
If the battery is running low, a red light is
flashing on the charge level display and
the motor is reducing its speed. Once the
battery is empty, the motor will stop; it will
need at least a 30-minute charge for one
usage.
•
You can always store the handle on the
plugged-in charging unit to maintain it at
full power; a battery overcharge is pre-
vented by device.
Note: Store handle at room temperature
for optimal battery maintenance.
Caution:
Do not expose handle to tem-
peratures higher than 50 °C.
Using your toothbrush
Brushing technique
Wet brush head and apply any kind of tooth-
paste. To avoid splashing, guide the brush
head to your teeth before switching on the
handle (picture
2
). When brushing your
teeth with one of the Oral-B oscillating-ro-
tating brush heads guide the brush head
slowly from tooth to tooth, spending a few
seconds on each tooth surface (picture
3
).
With any brush head start brushing the out-
sides, then the insides and finally the chew-
ing surfaces. Brush all four quadrants of
your mouth equally (picture
3
). You may
also consult your dentist or dental hygienist
about the right technique for you.
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 con-
sult your dentist or dental hygienist. If you
have sensitive teeth and/or gums, Oral-B
recommends using the «Sensitive» mode
(optional in combination with an Oral-B
«Sensitive» brush head).
Smart Ring features
Your toothbrush is equipped with a Smart
Ring (2) that has various functionalities indi-
cated via different colors of light:
White (default) = Operating and visual timer
light (choose individual color via Oral-B
TM
App settings)
Red = Pressure sensor light
Blue =
Bluetooth
®
pairing indicator
Timer
The timer signals with a short stuttering
sound and a flashing light of the Smart Ring
at 30-seconds intervals to move to the next
quadrant of your mouth (picture
3
). A long
stuttering sound and a flashing light indicate
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,
briefly pressing the mode button (4) during
pause or placing the handle on the
plugged-in charger.
Note: During the use of the Oral-B
TM
App,
the timer may be deactivated for some
features.
Note: You can also customize the timer
settings via Oral-B
TM
App.
Pressure sensor
If too much pressure is applied, the Smart
Ring (2) will light up in red, reminding you to
reduce pressure. Constant high pressure for
more than 5 seconds is indicated with a fast
flashing Smart Ring (2). In addition the pul-
sation of the brush head will stop and the
oscillation movement of the brush head will
be reduced (during «Daily Clean», «Pro
Clean» and «Sensitive» mode) (picture
3
).
Periodically check the operation of the pres-
sure sensor by pressing moderately on the
brush head during use.
Note: During the use of the Oral-B
TM
App,
the pressure sensor may be deactivated for
some features.
Brushing modes
Your toothbrush offers different brushing
modes indicated on the brushing mode dis-
play (6) on your handle («Daily Clean» mode
does not illuminate on the brushing mode
display):
