SECTION 10 .. CIRCUIT SCHEMATICS
10-1 GENERAL
This section contains module interconnect drawings and individual module
circuit schematics. Except when specifically identified, the drawings
apply to both , the FM/AM-500 and FM/AM-500A. Although some modules
include multiple PC boards and /or components i nstal 1 ed directly in an
enclosure block or on the chassis, the entire circuit is shown in the
related schematic.
Reference designator series numbers assigned to
the individual PC boards , the enclosure blocks,
etc., are within the board and /or module identi­
fication block and in accompanying notes. While
the text refers to a component by the complete
designator number, such as R 3201, the schematic
shows the series in the identification block and
notes only. R 3201 would show 3200 as the series
