Philips sonicare DiamondClean 9000 Series Manual page 39

ENGLISH
5 To clean the inside surfaces of the front teeth, tilt the brush
handle semi-upright and make several vertical overlapping
brushing strokes on each tooth.
Note:
- A change in vibration from the handle alerts you when you
apply too much pressure (see ‚Pressure sensor').
- Your Philips Sonicare toothbrush is safe to use on braces,
dental modifications and dental restorations (fillings, crowns,
veneers)
- Do not use your power toothbrush in the shower.
BrushSync technology
BrushSync technology enables your brush heads to communicate
with your handle using a microchip. The symbol at the bottom of
the brush head indicates that it is equipped with the BrushSync
technology. This enables the following features:
- Brush head mode pairing
- Brush head replacement reminder
Brushing modes
Your power toothbrush is equipped with 4 different modes: clean,
white+, gum health and deep clean+.
Based on the smart brush head you use, the optimal mode and
intensity will be selected automatically by the BrushSync technology.
