Pad Placement Guidelines:
Proper pad placement is crucial for effective treatment. Refer to the diagram below for recommended massage points.

This circular diagram illustrates various recommended massage points on the human body for electrode pad placement. It shows examples of pad placement on the back, shoulders, lower back, legs, and abdomen, guiding users on where to apply the pads for optimal pain relief.
- Place pads on clean, dry, healthy skin.
- For localized pain, place pads on either side of the painful area, ensuring they are not touching.
- Avoid placing pads directly over joints or bony prominences.
- Ensure good contact between the entire pad surface and the skin.
Using the Back Belt (if applicable):
The HealthmateForever YK15AB may be used with compatible accessories such as a back belt for broader application.

This image shows a person from behind wearing a black electrotherapy back belt. The belt is positioned around the lower back, suggesting its use for pain relief in that region.

This image provides a detailed view of the black electrotherapy back belt. It highlights the internal electrode pads and the adjustable straps, demonstrating the design and functionality of the belt for targeted pain relief.
- Connect the back belt to the device's output ports as you would with standard electrode pads.
- Wrap the belt around the desired area (e.g., lower back) and secure it comfortably.
- Ensure the internal electrodes of the belt make good contact with your skin.
- Adjust intensity as described above.
Maintenance and Care
Cleaning the Device:
- Turn off the device and disconnect all wires and pads before cleaning.
- Wipe the device body with a soft, slightly damp cloth. Do not use abrasive cleaners or immerse the device in water.
- Ensure the device is completely dry before storing or next use.
Caring for Electrode Pads:
- After each use, place the protective film back onto the adhesive side of the pads to prevent drying and maintain stickiness.
- Store pads in a cool, dry place, away from direct sunlight.
- If pads lose their stickiness, gently wipe the adhesive surface with a damp cloth and let air dry. Do not use soap or harsh chemicals.
- Replace pads when they no longer adhere well to the skin, as this can affect conductivity and treatment effectiveness.
Storage:
- Store the device and accessories in their original packaging or a protective case when not in use.
- Remove batteries if the device will not be used for an extended period to prevent battery leakage.
