Once your brush head is no longer effective, the brush head
replacement reminder will blink amber. This indicates that it is
recommended to change your brush head.
Note: The brush head replacement reminder comes activated
with your product. To deactivate this feature, see 'Activating or
deactivating features'.
Pressure sensor
Your Philips Sonicare measures the pressure you apply while
brushing to protect your gums and teeth from damage.
If you apply too much pressure, the handle will change its
vibration until you reduce the pressure.
Note: The pressure sensor comes activated with your product.
To deactivate this feature, see 'Activating or deactivating
features'.
Brush head mode pairing
Brush heads with BrushSync technology are equipped with an
RFID chip. The chip communicates to the handle and
automatically pairs it with the recommended mode and
intensity.
Note: If you change modes/intensity, the handle will remember
the last used setting. If you wish to brush with the
recommended setting, you can find the recommended
modes/intensity in 'Brushing Modes'.
