4. Setup and Application
Proper application ensures optimal conductivity and comfort during therapy.
- Prepare Skin: Ensure the skin area where electrodes will be applied is clean, dry, and free of oils, lotions, or hair. This improves adhesion and conductivity.
- Remove from Packaging: The electrodes arrive in a sealed bag to guarantee they are new and unused. Carefully open the bag.
- Peel from Backing: Gently peel the electrode pad from its protective backing film. The electrodes are positioned on a special backing sheet for easy re-storage after use.
- Apply to Skin: Apply the electrode pad firmly to the desired area of the skin. Ensure full contact to prevent uneven stimulation.
- Connect Device: Connect the electrode cable from your TENS/EMS device to the button connector on the electrode pad.

5. Operating Instructions
Once the electrodes are correctly applied and connected to your TENS/EMS device, refer to your device's instruction manual for specific program settings, intensity levels, and treatment durations. These electrodes facilitate various therapeutic applications:
- Pain Therapy: Provides drug-free pain relief for conditions such as back pain, neck pain, sciatica, heel pain, and other localized discomforts.
- Muscle Training: Supports targeted and joint-friendly muscle training to aid in rehabilitation or achieve sports-related goals.
- Electrostimulation Massages: Helps relax muscles and promotes overall well-being.

6. Maintenance and Care
Proper maintenance extends the lifespan and effectiveness of your axion electrode pads.
- After Each Use: Carefully detach the electrode pads from your skin. Re-apply them to their original protective backing film.
- Storage: Store the electrodes in their sealed bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Restoring Adhesion: If the adhesive strength decreases, gently moisten the adhesive surface with a small drop of water to reactivate it. Allow it to air dry slightly before re-applying.
- Cleaning: Do not use harsh cleaning agents, alcohol, or abrasive materials on the electrodes, as this can damage the gel layer.
- Replacement: Replace electrodes when they no longer adhere effectively or if they show signs of wear and tear, such as cracking or discoloration.
7. Troubleshooting
- Poor Adhesion: Ensure the skin is clean, dry, and free of oils. If adhesion is still poor, gently moisten the gel surface with a small amount of water and allow it to become tacky before re-application.
- Weak or Uneven Stimulation: Check all cable connections to ensure they are secure. Verify that the electrodes are fully adhered to the skin without air pockets. Ensure your TENS/EMS device is functioning correctly and its battery is charged.
- Skin Irritation: If skin irritation occurs, remove the electrodes immediately. Ensure proper skin preparation. If irritation persists, discontinue use and consult a healthcare professional.
- No Stimulation: Check that the TENS/EMS device is turned on and functioning. Verify that the cables are securely connected to both the device and the electrodes. Ensure the electrodes are making full contact with the skin.
