Motorola APX 7000 Detailed Service Manual

Chapter 8 Schematics, Boards Overlays, and Parts Lists
This chapter contains the schematics, board overlays, and parts lists
for the APX 7000/APX 7000XE 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 online 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 7000/APX 7000XE radio are found.
