Adaptive intensity
Scrubbing Feedback
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'.
