• Divided schematic diagram
Schematic diagrams of A, AD, B, D, G, and U boards are divided into several
pieces. Information to where the line is to be connected is printed
at the end of each.
For example, [ TO A1/5,A2/5_1 ] means the line is connected to
Ref. No. 1 of A(1/5) and A(2/5) schematic diagrams.
