Can I use multiple TensRelief electrodes at the same time?
TensRelief (PR3093) is intended to be used with 2 electrodes at a time. TensRelief Pro (PR3094) is intended to be used with either 2 or 4 electrodes at a time.
If you would like to treat larger areas, e.g. on your back or knee, you can also use 2 devices (4 electrodes) at the same time. Using 2 devices (4 electrodes) at the same time is not meant to be used for application to different body areas.
