Intensity settings
Your power toothbrush gives you the option to
choose between 3 different intensity levels: low,
medium and high. Based on the brush head you
attach, the intensity will be selected automatically.
If you wish to change to a different intensity, you
can do so by pressing the mode/intensity button
while brushing. For optimal results it is
recommended to use the automatically selected
intensity. The intensity cannot be changed as long
as the handle is powered off or paused.
