I own the Fischer MD-1A model yet stopped using it several years ago due to switching over to a pulsed current unit. The MD-2 just has more bells and whistles but basically accomplishes the same task.
Set the machine at setting that you feel the sting, yet make sure it's tolerable. 15 minutes each polarity for a total of 30 minutes. That's if you are just treating your hands.
If you are doing one hand, one foot method your total treatment time will an hour.
Do this every day for the first 7-10 days, stop and assess your dryness.
