Motorola APX 6000 Service Manual

Chapter 8 Schematics, Boards Overlays, and Parts Lists
This chapter contains the schematics, board overlays, and parts lists
for the APX 5000/APX 6000/APX 6000XE/SRX2200 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 5000/APX 6000 radio/APX 6000XE/SRX2200
are found.
