Electrode Pad Placement

Proper placement of electrode pads is crucial for effective and safe treatment. Refer to the included user manual for detailed diagrams and recommended placements for specific pain areas. Generally, place pads on clean, dry skin, ensuring they are not directly over joints, open wounds, or sensitive areas. For dual-channel use, ensure pads for each channel are placed on the same side of the body or on areas that require similar intensity.

Maintenance and Care

• Cleaning the Device: Wipe the TENS unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.
• Cleaning Electrode Pads: If the adhesive on the pads becomes less sticky, gently wipe the adhesive surface with a damp cloth or a drop of water. Allow them to air dry completely before re-applying the protective film.
• Storage: Store the device and pads in the provided storage bag in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the protective film is reapplied to the pads after each use to prolong their lifespan.
• Battery Care: Recharge the device regularly, even if not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.

Troubleshooting

• No Sensation: Ensure the device is turned on, the intensity is set above zero, and both electrode pads for the active channel are firmly attached to the skin. Check that the electric wires are securely plugged into both the pads and the device.
• Weak Sensation: Increase the intensity level gradually. Ensure the pads are making full contact with clean, dry skin. The pads may need cleaning or replacement if they are old or dirty.
• Irritation at Pad Site: Discontinue use if skin irritation occurs. Ensure pads are not placed over broken or irritated skin. Clean the skin thoroughly before application.
• Device Not Turning On: Check the battery level. If low, charge the device using the USB-C cable.
• Uneven Sensation Between Channels: Verify that the intensity levels for Channel A and Channel B are set appropriately and independently.
