I’m not sure how to use the timer in the control panel
The “Time” button adjusts your treatment time by increments of 1 minute, with a maximum treatment time of 20 minutes. The time will cycle back to 1 minute when the display exceeds 20 minutes. When the desired treatment time is selected, it will be shown on the display.
Pressing “Play/Pause” will start the treatment. If you press “Play/Pause” again during the treatment, your session will pause. When your session is paused, the time is rounded up to the nearest minute. Your device will remember treatment times you program for future sessions.
