Up for sale is an Earthcalm Scalar EMF Home protection system. Used for a few years. Traveled with a few times. I do not have the manual but it should be available online. Basically you start out with the base unit for a week and then add the modules one at a time for desired effect. This EMF protector gives protection that extends equally throughout your home, no matter how much square footage you have, so you require just one system for your entire home. Because it provides protection to everyone in the home, the System is ideal for families with children, who are more vulnerable to EMFs than adults. The Scalar Home Protection System includes three progressive steps to moderate the adjustment period, which gently and gradually help you adjust to the powerful emf protection it provides. The Scalar Home Protection System utilizes the principles of cyclotronic resonance and scalar resonance. Each stage includes proprietary EarthCalm circuits that are modulated into the AC electrical current and broadcast throughout the entire house. The System, in addition, includes a voltage range of 110 to 240 that when modulated by the EarthCalm circuits totally breaks the grip of the electrical grid built into the home’s wiring system. Specifications: Measures 4? X 2? X 2? . The Scalar Home Protection System may be plugged in anywhere in the home to protect the entire household (and all electrified buildings under the same electrical meter). It will last indefinitely.
