Increasing the current

Intensity can only be changed once the session is running (countdown timer is counting down). You MUST increase the current to an effective level. This is done by pressing the Arrow Up on the right hand side of the device. Every time you press this button, the intensity will increase by 10 uAmp until you reach 200 uAmp. After that, intensity will increase in steps of 50 uAmp. You can also depress AND hold the Arrow Up key to increase the intensity more rapidly. The Arrow Down key, just below the Arrow Up key on the right, has the opposite effect.
