The pressure sensor feature is off by default when your toothbrush arrives. To turn on, press the power button for about 3 seconds. When you hear 1 beep, the sensor has been activated. If you are brushing too hard, it beeps to warn you, and it stops beeping when you are brushing gently and safely.
To turn off the pressure sensor feature, make sure the setting is on Clean Mode, then press the power button for about 3 seconds. When you hear 2 beeps, the sensor has been deactivated.
Note: the pressure sensor will only work when the brush is set to higher speeds of Clean Mode or the Sensitive Mode.
