4. Preparation and Setup
- Clean Skin: Ensure the skin area where the pads will be applied is clean, dry, and free from oils, lotions, or hair. This maximizes adhesion and conductivity.
- Connect Pads: Insert the 2mm pin lead wires from your TENS/EMS unit into the connectors on the electrode pads.
- Remove Protective Film: Carefully peel the electrode pads from their protective liner. Retain the liner for storage.
5. Application Instructions
Apply the pads firmly to the targeted skin area. Ensure the entire surface of the pad is in contact with the skin. Refer to your TENS/EMS unit's manual for specific program settings and intensity levels.

6. Removal Instructions
To ensure the longevity of your pads and prevent skin irritation, follow these removal steps:
- Turn off your TENS/EMS unit before removing pads.

7. Care and Maintenance
Proper care extends the life of your GHTENS TENS Machine Pads:
- Cleaning: If the adhesive surface becomes dirty or loses stickiness, gently wipe it with a damp cloth (water only). Do not use soap, alcohol, or abrasive cleaners.
- Storage: After each use, reattach the pads to their protective film and store them in the original resealable pouch. Store in a cool, dry place away from direct sunlight.
- Replacement: Replace pads when they no longer adhere well to the skin or if you notice a decrease in conductivity.

8. Troubleshooting
If you encounter issues with your TENS Machine Pads, consider the following:
- Poor Adhesion: Ensure skin is clean and dry. If pads are old or dirty, clean them or consider replacement.
- No Sensation/Weak Sensation: Check that the pads are firmly attached to the skin and the lead wires are securely connected to both the pads and the TENS/EMS unit. Ensure your TENS/EMS unit is powered on and set to an appropriate intensity.
- Uneven Sensation: Check pad placement and ensure both pads are making full contact with the skin. Uneven wear or damage to one pad may require replacement.
- Skin Irritation: Discontinue use immediately. Ensure skin is clean before application. If irritation persists, consult a healthcare professional.
