The unit is now ready to use. To test, cover the plate with a piece of spent film or a thin plastic sheet such as mylar. Place one fingertip on the plastic or film and push the button. There should be no extremely uncomfortable sensation whatsoever. It is normal to feel some heat or a tingling sensation.
Some people are very sensitive to the tingling of the electricity.
Although this is uncomfortable for them, it is totally harmless.
