- The interferential stimulator (IF) device is a battery operated device that includes two controllable output channels.
- Amplitude, mode and duration of the electrical impulses can be altered with the buttons or knobs.
- The controls are protected by a cover in order to prevent accidental changes to the settings.
- Slide the cover down to make adjustments to the controls.
