Your Sonicare toothbrush measures the pressure
you apply while brushing, to protect your gums
and teeth from damage.
If you apply excess pressure, the handle changes
its vibration and the brush head replacement
reminder icon flashes amber until you reduce the
pressure.
Note: Your product comes with the Pressure
Sensor activated. To deactivate this feature (see
'Activating or deactivating features').
The QuadPacer is an interval timer that helps you
to brush evenly through the mouth by dividing
your mouth into 4 sections. (See 'Brushing
instructions')
The SmarTimer indicates that your brushing cycle
is complete by automatically switching off the
toothbrush at the end of the brushing cycle.
Dental professionals recommend brushing no
less than 2 minutes twice a day.
