Band 1 high power, etc.).
All data on control heads–including board overlays, schematics, and parts lists–is contained in
Chapter 2, and all data on controllers is in Chapter 3.
The band-specific chapters (Chapters 4–13) each contain their own sections on:
model charts and technical specifications (Section 1)

theory of operation (Section 2)
•
troubleshooting charts (Section 3)
•
board overlays, schematics, and parts lists (Section 4)

overlay, schematic and parts list in the section.
