  If your Omron Massager turns off unexpectedly, there could be several reasons. First, the batteries might be weak or exhausted, so try replacing them with two new, identical 1.5V alkaline AAA LR03 batteries. Second, the treatment period of 15 minutes may be over, as the power turns off automatically after this time; in this case, restart the treatment or turn off the massager. Finally, the electrode cord might be broken, requiring a replacement.

  If you're finding it hard to feel the stimulation from your Omron Massager, there are a few things to check. Ensure the Long Life pads are attached firmly to your skin and that they are not overlapping each other. Also, verify that the electrode cord is connected correctly. Finally, the intensity might be too weak, so try increasing it by turning the dial switch.

  Rebecca RichardsonAug 25, 2025
  If your skin turns red or feels irritated after using the Omron Massager, it could be due to a dirty or dry adhesive surface on the Long Life pads. Try washing the adhesive surface softly with your fingertips for about 3 seconds under slow running water. Alternatively, the Long Life pads may be damaged, requiring replacement.
