hello! take the ear piece and unfold it to 45 degrees, than pull it off . see the little splits on the end where the earpeace goes onto the body off the tooth? thats motos design for slipping it off the pins. than turn the earpiece around and put er back on. a little bit of a tussle till you get use to it. if your confused as i was put the earpeace on your other ear and the light will turn on and youll go (like me) oh yea!! i see, than youll go easy breezy. good luck. m.m.
