Motor ONWhen the tonearm is moved down on the surface of therecord, the feed arm moves in the direction of an arrowso that SW2 turns ON to start the motor. 2. Tonearm ReturnWhen the tonearm arrives at the end of the record, anoperation as shown below is performed. Thus, the gear ofthe center shaft is engaged with the ring gear to startcounterclockwise rotation.By the ring gear assy alone, the tonearm actuator movesin the direction of arrows to return the tonearm.
