Charge the unit fully and press the pads onto clean, dry, unbroken skin. Skin cream, sweat and hair all stop pads sticking.
Open Session, pick the body area and what you are treating, then let the app send the settings down. You never type a frequency — the app holds the settings and the device checks them against its own limits.
Start at the lowest comfortable level. A steady tingle or a light pulling feeling is right. Sharp, stinging or burning is too high.
Sit still for the countdown. Peel pads off slowly afterwards and store them on their plastic backing.
