The right level is the maximum suction that remains comfortable for you.
1. Start at a lower level and increase one level at a time.
2. The Mode Button selects Stimulation or Expression mode; there are 7 levels in stimulation mode and 10 levels in expression.
3. Use the Level Up/Down Buttons to adjust.
4. Higher suction does not always mean more output — comfort and correct fit matter more.
