This theory only applies when the rife machine includes remote mode. When you run contact or plasma, the 2 signals interfere with each other. But you can run more than one remote at the same time, or you can run remote together with contact or plasma.
So why running two at the same time – Healing & Rejuvenation.
There is a specific purpose behind running two Rife (machine) generators at once. One Rife generator is running various detoxification frequency sets, while the other Rife machine generator is running broad range spectrum Rife frequency sweeps. The concept or strategy is that, assuming the Rife frequency sweeps do in fact disable, destroy, kill or immobilize microbes, pathogens, bacteria and viruses, the result would be toxic debris from the destroyed microbes, pathogens, bacteria and viruses. The frequency sets to detoxify the lymph system, liver and kidneys are an attempt to address the potential detoxification issue. The potential of the technology is phenomenal.
