Ken,
Please ignore my previous message that there is no light when I set up the machines. Embarrassing, but it was because my electrodes were not pushed in well and eventually fell off the generator. To make higher ppm, I put it on manual and swap modes. Is that ok, or should it be in manual and dc modes? Thanks. Melly When diet is wrong, medicine is of no use.
