How To Use It - to kill bacteria, viruses and parasites Dampen the sleeve covers for the pipe handles (or wrist strap covers, as the case may be) and sprinkle salt on them if you are using distilled water. Plug the handle cords (wrist strap cords) into the sockets on the end of the zapper. Turn the zapper on, using the slide switch on the end. The red light should come on. If it flickers, then the 9V battery should be replaced. Touch the bare metal of each probe to the test points on opposite sides of the zapper, and the green light should come on - that proves the signal is reaching the probes. Now forget the test points, and hold one probe in each hand (or wear both wrist straps) for 7 minutes, without crossing your arms or legs. Take a 20 minute break, and then do the 7 minutes again, followed by another 20 minute break, and a final 7 minutes. After each 7 minute session, turn off the zapper. Do not eat or drink between zaps. Do this once per day. It takes the three back to back sessions to kill the invaders. Hulda’s conclusion is that the second zap kills invaders that fled the ones killed in the first zap, and the third and final zap kills ones that fled those killed in the second zap. See page 15 of The Cure For All Diseases. Some people read books or watch the news while zapping. The zapper does not kill shielded organisms, such as those in the middle of your stomach or intestines. Herbs are helpful in reaching those organisms.
