Choice of level
Press and hold the button, release at the desired level. When activated, the "Hydrosonic pro" starts at the last selected level. The movement of the bristles decreases immediately and automatically in case of excessive pressure.
- Before first use, fully charge "Hydrosonic pro".
- You can see the charge status of your toothbrush as soon as it is unplugged from the charger or when you switch it off.
- If all seven LEDs of the LED display are lit, then the battery is fully charged: the more LEDs are lit, the more charged the battery is.
- If the bottom LED is lit red instead of blue, then the battery is less than 20% charged.
- To recharge the toothbrush, place it in the mains-connected charger: Connect the USB connection of the charger to the USB plug of the mains power supply and this to the mains. You can also charge the device via the USB port of your laptop or computer.
- Once fully charged, the battery lasts for 60 minutes, which is about two weeks if you brush your teeth four minutes a day.
- Optimum battery charge time: ten hours.
Extremely long life cycle: only recharge the device when the battery charge level has dropped below 20% (red LED on).

"start" level
The start level is recommended for cleaning brackets, archwires and wires with the help of the "single" application. It works with 44,000 oscillations per minute. The bottommost LED is on. Also, this level is good for getting used to the slight tingling that a sonic toothbrush causes.
Three "clean" levels
We then continue with the clean mode, which is in turn divided into three different levels of intensity, each with 64,000 oscillations per minute; for each level, a further LED on the display gradually lights up.
Tip: "sensitive" or "power" head.
Three "similar" levels
Smile mode, divided in turn into three different levels of intensity, each with 84,000 oscillations per minute, until all the LEDs are on. Subsequently the levels restart from the beginning.
Tip: "sensitive" or "power" head.

Teeth cleaning with dental appliances
With the "sensitive" or "power" head, first pass on the side of the attachment facing the gum, from tooth to tooth, then above or below the attachment, selecting one of the levels from "clean" to "smile" . In this way, the gingival sulcus is also cleaned at the same time. Finally, clean the other side of the attachments as well, tooth by tooth.
Brackets
%Egrave; It is possible to clean the contact points in this way: with the "single" brush head, move at a minimum movement speed around the attachments, slowly and carefully and with almost no pressure, by selecting the "start" level.
Lingual brackets and retainers
What has been said also applies to brackets that are fixed on the inside of the teeth towards the tongue: pass slowly
