3、CHANISM DESCRIPTION Operation 1. Motor ON When the tonearm is moved down on the surface of the record, the feed arm moves in the direction of an arrow so that SW2 turns ON to start the motor. 2. Tonearm Return When the tonearm arrives at the end of the record, an operation as shown below is performe
4、d. Thus, the gear of the center shaft is engaged with the ring gear to start counterclockwise rotation. By the ring gear assy alone, the tonearm actuator moves in the direction of arrows to return the tonearm. RadioFans.CN 收音机爱 好者资料库 KD-291R/291RC 3 MECHANISM DESCRIPTION 3. Cueing a. For manual retu
