When using the electrode plate, it is necessary to fasten the electrode buckle and the electrode plate, then insert the plug of the electrode buckle into the product input socket, and then stick the electrode plate on the place where massage is needed. It should be noted that the surface of the electrode sheet should be kept clean. After all, it is close to the skin. At the same time, the two electrode plates should not touch each other. In addition, do not pull the cable directly when taking it off after use.
