Adaptive intensity
Scrubbing Feedback
If you apply excess pressure, the handle will change
its vibration and the brushing feedback light will flash
(purple) at the bottom of the handle until you reduce
the pressure.
Note: The Pressure Sensor comes activated with your
product. To deactivate this feature, see 'Activating or
deactivating features'.
Your Sonicare toothbrush is designed with Adaptive
Intensity to protect your gums. If you apply excess
pressure for an extended period of time, your
toothbrush will automatically lower the intensity
setting 1 level. You will experience a brief pause in the
pressure feedback and feel the intensity adjust to the
next lower level.
Note: Adaptive Intensity comes activated with your
product. To deactivate this feature, see 'Activating or
deactivating features'.
Note: Every new brushing cycle the intensity will go
back to your pre-selected setting.
Your Sonicare toothbrush measures the motions while
brushing to detect scrubbing behavior (see brushing
instructions for optimal technique). If you regularly
scrub while brushing, the app will recommend that
you enable Scrubbing Feedback.
When Scrubbing Feedback is activated the brushing
feedback light at the bottom of the handle will
illuminate amber and the handle will change its
vibration as a reminder to stop scrubbing. The
brushing feedback light will turn off when you stop
scrubbing.
Note: Scrubbing Feedback comes deactivated. To
activate this feature, see 'Activating or deactivating
features'.
