Compex CoreBelt App - How to Place the Electrode Pads

How to Place the Electrode Pads

The double sticky sides electrodes should be positioned on the belt according to the placement markings outlined on the belt. Open the pack of electrodes, remove the plastic from the grid pattern side.

  • Abs session -> Front electrodes only
  • Back session -> Back electrodes only
  • Core session -> Front and Back electrodes

Stick the electrodes grid side down in-line with the outlines. At this point the visible side of the electrodes should be plain black.

We recommend placing the four electrodes, two on the front and two on the back, even if you stimulate only the abs or only the low back. Make sure that the metallic pins are completely covered by the electrodes.

Only use this device with electrodes recommended by Compex.

Adjusting the Intensity

When you select an objective, you’ll be taken to a screen with the objective timing and intensity settings. Here you can adjust the intensity by tapping the plus sign “+” to increase or the minus sign “-“ to decrease the levels. Push the pause/play button if you need to pause for a moment.
