The NuCalm Biosignal Processing disc is programmed for single use only. One NuCalm session = one disc. Once the disc touches the skin, it begins delivering the biosignals to the body, and it will do so for the duration of your NuCalm session. You may leave the NuCalm disc on for the remainder of the day or to sleep for residual calming effects, however, use a new disc with every new NuCalm session.
How many times can I use the disc?
