The package contains the following items:
- 4 x Prorelax 39183 Electrode Pads
3. Setup and Application
- Prepare the Skin: Ensure the skin area where the pads will be applied is clean, dry, and free from lotions, oils, or hair. This helps maximize adhesion and conductivity.
- Connect to Device: Carefully attach the electrode pad wires to the lead cables of your Prorelax TENS EMS DUO device. Ensure a secure connection.
- Apply Pads: Remove the protective film from the adhesive side of the electrode pads. Apply the pads firmly to the desired skin area. Ensure the entire surface of the pad makes contact with the skin.

4. Operating Instructions
Once the electrode pads are securely applied and connected to your Prorelax TENS EMS DUO device, refer to your device's instruction manual for specific operating procedures. The pads facilitate the electrical impulses from the device to your body. Ensure the device is turned off before applying or removing pads.
- Always follow the instructions provided with your Prorelax TENS EMS DUO device for program selection, intensity adjustment, and treatment duration.
- Ensure the pads maintain full contact with the skin throughout the treatment session for effective and comfortable therapy.
5. Care and Maintenance
Proper care extends the lifespan of your electrode pads:
- Storage: After each use, carefully remove the pads from your skin and re-apply them to their original protective film. Store them in a cool, dry place, preferably in their sealed bag, to prevent drying out.
- Cleaning: Do not wash the electrode pads with water or cleaning agents, as this can damage the adhesive and conductivity. The pads are designed to be self-adhesive and reusable.
- Lifespan: The reusability and durability of the pads depend on skin preparation, storage, and frequency of use. Replace pads when they no longer adhere effectively or when conductivity diminishes.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pads do not adhere well to skin. | Skin is oily, dirty, or hairy; adhesive is worn out. | Clean and dry skin thoroughly before application. If pads are old, replace them with new ones. |
| Weak or inconsistent electrical sensation. | Poor pad-to-skin contact; pads are dry or worn out; loose connection to device. | Ensure full pad contact. Check wire connections. Replace pads if they are no longer conductive. |
