Clean and dry the application area. Apply electrodes only to unbroken skin. 2. Open and remove electrodes from packaging. Keep original packaging for storage. 3. Peel electrodes from release sheet by lifting the edge. Do not pull by the wires. 4. If pads appear dry or do not adhere well, apply a few drops of water to moisten the gel and wait a few minutes to rehydrate. 5. Place electrodes on the treatment area. Press firmly along the edges and over the entire surface to ensure good skin contact. Removal: 1. Gently peel off the electrodes. 2. Clean the electrodes with a non-alcohol wipe or rinse with cold water, then allow to air dry. Keep the sticky side facing up to avoid contamination. 3. Place the sticky side back onto the clear liner and return to the original packaging. 4. Store in a cool, dry place away from direct sunlight and extreme temperatures, which may damage the gel. Electrodes may also be stored in the refrigerator to extend lifespan.
