Connecting and Charging
Your toothbrush has a waterproof handle, is electrically safe and
designed for use in the bathroom.
• Plug the charger (g) into an electrical outlet and place the
toothbrush handle (d) on the charging unit.
• The green charge indicator light (e) flashes while the handle is
being charged. Once it is fully charged, the light turns off. A full
charge takes typically 14 hours and enables up to seven days 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 10–15 minutes.
• If the rechargeable battery is low the red charge indicator light (f)
is flashing for some seconds when turning your toothbrush on/off.
• For everyday use, the toothbrush handle can be stored on the
charging unit to maintain it at full power. Overcharging is
impossible.
• To maintain the maximum capacity of the rechargeable battery,
unplug the charging unit and fully discharge the handle with
regular use at least every 6 months.
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). Guide the brush head slowly from tooth to
tooth, spending a few seconds on each tooth surface. Start
brushing the outsides, then the insides and finally the chewing
surfaces. Brush all four quadrants of your mouth equally (picture 5).
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» mode (optional in combination
with an Oral-B «Sensitive» brush head).
