Setup and Application
Preparation:
- Before placing the electrodes, thoroughly wash the skin area where the electrostimulation session will be performed with soap and water. Ensure the skin is clean and dry for optimal adhesion and conductivity.
- Carefully remove the electrode from its sealed packaging. The electrodes come in a sealed bag to ensure they are new and unused upon receipt.
- Peel the electrode from its protective film. Retain this film for storage after use.
Application:
- Connect the 2 mm pin connectors of the electrode to your TENS/EMS device.
- Apply the adhesive side of the electrode firmly to the appropriate body area. For lower back pain, position the large electrode to cover the affected lumbar region.
- Ensure the entire surface of the electrode is in contact with the skin to guarantee uniform current distribution.
- Once applied, you can begin your electrostimulation session according to your device's instructions and your therapy needs.

Usage and Care
To maximize the lifespan and effectiveness of your axion electrodes, follow these care instructions:
- Reusability: These electrodes are designed for multiple uses. The number of uses depends on skin preparation, storage, and frequency of use.
- Cleaning Skin: Always ensure the skin area is clean and free of oils, lotions, or sweat before application. This significantly improves adhesion and extends electrode life.
- Storage: After each use, carefully re-apply the electrode to its original protective film. Store the electrodes in their sealed bag or a cool, dry place away from direct sunlight.
- Adhesion Renewal: If adhesion decreases, gently dab the adhesive surface with a few drops of water. Do not use alcohol or other solvents.
- Replacement: Replace electrodes when they no longer adhere well to the skin or if the conductivity feels uneven.

Troubleshooting
If you experience issues with your axion electrodes, consider the following common solutions:
- Poor Adhesion: Ensure the skin is clean and dry before application. If the electrode is old, its adhesive properties may have diminished, and replacement might be necessary. Gently dabbing the adhesive side with a few drops of water can sometimes restore stickiness.
- Uneven Stimulation/No Sensation: Check that the electrode is fully in contact with the skin across its entire surface. Ensure the pin connection is securely inserted into your TENS/EMS device. Verify your device is powered on and set to the correct program and intensity.
- Skin Irritation: Although designed to be skin-friendly, some individuals may experience irritation. Ensure the skin is clean before application. If irritation persists, discontinue use and consult a healthcare professional.
- Electrode Damage: Inspect electrodes for any visible damage, tears, or dry spots. Damaged electrodes should be replaced immediately to ensure safe and effective treatment.
