Clever Start function
Ultrasonic toothbrushes can tickle the first time you use them. You can use the Clever
Start function to slowly get used to brushing your teeth with a ultrasonic toothbrush. The
Clever Start function gradually increases the frequency of the sonic vibrations over the
course of the first 14 applications. If the Clever Start function is activated, the corre-
sponding LED on the programme display flashes during use. A cleaning cycle must be
carried out completely (2 minutes) in order to be counted. After 14 cleaning cycles, the
Clever Start function will shut off automatically. The corresponding LED on the pro-
gramme display now lights up permanently during use.
