Function Control Switch

Fig. 25 Function control switch terminals.:

1. Using a suitable ohmmeter check resistances between "a" and "b" terminals when pushing the button, Fig. 25.
2. When the REC button is pushed in, there should be continuity between the "e" and "g" terminals. There should be no continuity between "e" and "f" terminals, but continuity when REC button is released.
