Wet the toothbrush and touch the brush’s metal band with your finger. Moistening the fingers will increase the flow of negative ions. Brush normally while maintaining contact between your fingers/palm and the metal band.
To remove a brush head, twist the handle while holding the brush head. To attach brush head, snap a new brush head into place over the silver bar.
Clean the brush head and silver bar whenever you can, since toothpaste can sometimes clog the in-between spaces.
Push button to test the battery. The red light indicates the battery still has power.
