Reference Symbols

Reference Symbols





Two reference symbols are used to indicate the remainder of the circuit (feed and ground) and refer the reader to one of two preliminary figures.


Reference Flags





This symbol refers the reader to a figure number only. It does not refer to a flag with the same number on a different figure.


As used in figures 1, 2 and 3, the FLAG refers to a figure number where the circuit is continued. In this instance, the reader matches the BOX or DIAMOND numbers to trace the circuit.


In most other cases, it is not necessary to refer to another figure for completion of a circuit. The FLAGS are used to indicate parallel circuits and circuits which share components. Most of the circuits where this situation occurs are overlapped to avoid the necessity for cross-referencing to another figure.
