Chapter 8 Schematics, Boards Overlays, and Parts Lists

This chapter contains the schematics, board overlays, and parts lists
for the APX 2000/ APX 4000/ APX 1000 (900 MHz) radio. Use them
in conjunction with the theory of operation and the troubleshooting
procedures, charts, and waveforms to isolate a problem to the
component level.
When schematics are viewed on line or as a PDF file, colors can be
seen that denote power and signal paths. The red color denotes
voltage paths, blue denotes the receive path, and green denotes the
transmit path.
The following tables list the pages where the schematics and board
overlays for the APX 2000/ APX 4000/ APX 1000 (900 MHz) radio are
found.
