Charging and Operating
Your toothbrush is electrically safe and designed for use in the
bathroom.
• You may use your toothbrush right away or charge it briefly
by placing it on the plugged-in charger (f).
Note: In case the battery is empty (no charging light illu-
minated (e) while charging or no reaction when pressing
the on/off button (c)), charge at least for 30 minutes.
• The charge indicator light (e) flashes green while the han-
dle is being charged. Once it is fully charged, the light
turns off. A full charge typically takes 12 hours and ena-
bles at least 2 weeks of regular brushing (twice a day, 2
minutes) (picture 1).
Note: After deep discharge, the charge indicator light
might not flash immediately; it can take up to 30 minutes.
• If the battery is running low, the charge indicator light (e)
flashes red for a few seconds when turning your tooth-
brush on/off 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 charg-
ing unit; a battery overcharge is prevented by device.
Note: Store handle at room temperature for optimal battery
maintenance.
Caution: Do not expose handle to temperatures higher
than 50 °C. Recommended ambient temperature for
charging is 5 °C to 35 °C.
Using your toothbrush
Brushing technique
Wet brush head and apply any kind of toothpaste. To
avoid splashing, guide the brush head to your teeth
before switching on the appliance (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 5).
With any brush head do not forget to brush all 3 surfaces
of your teeth: chewing, outer and inner 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.
