How does the Pressure Guard Sensor work?

You can choose the level of feedback of the light ring that you want to receive by tapping the button with three dots on the shaver handle when the shaver is switched on. 

The following options are available, with numbers corresponding to the illustrations below:

1. Full pressure feedback: the light ring will change color depending on how much pressure you apply. Blue denotes too little pressure, green indicates that the correct pressure is being applied, and orange denotes too much pressure
2. Partial pressure feedback: the light ring will only illuminate (in orange) if too much pressure is being applied.
3. No pressure feedback: the light ring will be switched off and pressure feedback will not be provided.

Note: pressure feedback is only provided when the shaving unit is attached. Pressure feedback is not provided for other attachments (e.g. cleansing brush or beard styler).
