-Easy-start

The brushing power will gently increase to full power over the first 14 brushings.

The Easy-start feature is active if you hear 2 beeps immediately after turning on your toothbrush.

Once you reach the optimal brushing power, after the 14th brushing, you will no longer hear the double beep at the beginning of the brushing routine.

Easy-start can also be switched off.

-Extra-soft bristles

Extra-soft, rounded bristles ensure deep, yet gentle cleaning

-Quadpacer

The Quadpacer feature ensures that you brush all sections of your mouth evenly and thoroughly.

At 30-second intervals (at 30, 60 and 90 seconds in case of a 2-minute brushing cycle), you will hear a short beep and notice a brief pause in brushing action. This is the signal to move to the next section of your mouth

The programmable Quadpacer allows you to customise the performance of the Quadpacer in one of the 3 ways.

-You can opt to keep the factory default setting of the 2-minute brushing time with Quadpacer beeps activated.

-You can opt to keep the factory default setting of the 2-minute brushing time with Quadpacer beeps deactivated.

-You can extend the brushing time to 2.5 minutes, by adding an additional 30-second interval.

-Dual speed control

Allows you to choose between 2 speed settings, normal speed for optimal brushing performance or reduced speed when an even more gentle brushing action is desired.

-Battery charge indicator

If the battery charge of your toothbrush is too low, you will hear 3 beeps after you have brushed your teeth for

2 minutes and the charge indicator LED will blink yellow for 30 seconds. When the handle is placed in the charger, the green charge indicator LEDs will blink in a rising pattern as the battery charges. The number of blinking LEDs indicates the level to which the battery has been charged.
