EasyStart
This Philips Sonicare model comes with the EasyStart feature
deactivated. The EasyStart feature gently increases the power over
the first 14 brushings to help you get used to the brushing with the
Philips Sonicare.
To activate EasyStart see 'Activating or deactivating features'.
Brush head replacement reminder
Your Philips Sonicare is equipped with BrushSync technology that
tracks the wear of your brush head. (Fig. 13)
1 When attaching a new smart brush head for the first time the
brush head replacement reminder light blinks green three times.
This confirms you have a Philips brush head with BrushSync
technology.
2 Over time, based on the pressure you apply and the amount of
time used, the handle will track brush head wear in order to
determine the optimal time to change your brush head. This
feature gives you the guarantee for the best cleaning and care of
your teeth.
3 When the brush head replacement reminder light lights up amber,
you should replace your brush head.
To deactivate the brush head replacement reminder see 'Activating or
deactivating features'.
Pressure sensor
Your Philips Sonicare is equipped with an advanced sensor that
measures the pressure you apply while brushing. If you apply too
much pressure, the toothbrush will provide immediate feedback to
indicate that you need to reduce the pressure. This feedback is given
by a change in vibration and therefore brushing sensation.
