This Button is the first part located on the side surface of the Cane, after the junction with the white cane. When the Cane is held perpendicular to the ground, it is the lower of the two buttons on the side surface of the Handle. The button has a round shape.
This button allows you to adjust the volume level of the Smart Cane 2 by clicking, and calibrate the compass of the Smart Cane 2 by long-pressing.
