- Power On & Adjust: Turn on the device. Select the desired mode and intensity using the controls. The intensity for the pads can be adjusted separately from the foot massage intensity if the device supports it, or it will be synchronized.
- Remove Pads: After use, gently peel off the electrode pads from your skin.
