the wire and the board. Tighten the screw to 23.0 kg cm (20 inch-pounds).
13. Connect wire 2 to J21. This time, put the connector for the work lead closest to the power board and put the ring

14. Replace the rear panel and secure it with the screw. Replace the Mylar barrier in front of the power board. Replace
the cover.
