5. Operation
5.1 Applying the Pads to Skin
Ensure your skin is clean and dry before applying the electrode pads. Remove the protective film from the adhesive side of the pad.
- Place the pads firmly on the desired area of your body. Common application areas include the shoulder, back, waist, arm, thighs, and calf.
- Avoid placing pads over joints that move frequently, as this can reduce adhesion.

5.3 Adjusting Intensity
The device offers 16 intensity levels to customize your experience.
- While the device is on and a mode is selected, use the '+' and '-' buttons on the controller or charging case to increase or decrease the intensity.

6. Maintenance
6.1 Cleaning Electrode Pads
To maintain optimal adhesion and hygiene, clean the electrode pads regularly.
- When the electrode pad loses its stickiness, gently rinse the adhesive surface with a small amount of water.
- Carefully scrape off any residue on the surface.
- Allow the pads to air dry completely. Do not wipe with a cloth or tissue, as this can leave fibers.
- The stickiness should be restored after drying. If not, it may be time to replace the pads.
6.2 Storage
Proper storage extends the life of your device and pads.
- After each use, reattach the protective film to the adhesive side of the electrode pads.
- Place the controllers (with pads attached) back into the charging case. The case provides a secure and organized storage solution while also recharging the controllers.
- Store the charging case and all accessories in the provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
