How do I increase therapeutic intensity?

During a therapy session, you can increase intensity by pressing and holding the button. Wait until after the first two minutes of a therapy session to adjust the intensity. This allows the device to ramp up to calibrated intensity. To manually increase therapeutic intensity, press and hold the device button for approximately 3-4 seconds and release. Each second of clicking & holding the button will increase the intensity by 1.25%. The lights should cascade up and down, showing that the intensity has increased. Therapy intensity can also be increased using the Quell Relief App.
