Chapter 6 Disassembly/Reassembly Procedures
6.1 Introduction
This section details the procedures necessary to remove and replace the printed circuit board in the
PM1200 radio. After troubleshooting and determining what needs to be replaced, disconnect the test
equipment, the antenna cable, and the power cable.
Locate the exploded view of the radio in Chapter 9. Exploded Views and Parts Lists . Keep it handy
for reference as you disassemble and reassemble the radio.
When installing a new circuit board, all mounting screws should be started before any are torqued.
This will help ensure proper alignment.
After installing a new board, perform a complete alignment procedure as outlined in Chapter 5. Radio
Alignment and Programming Procedures .
6.2 Replacement Procedures
6.2.1 Required Tools and Supplies
Disconnect the power cable from the radio before
opening and removing the PCB. Failure to remove power
can result in unit damage caused by transients or
accidental shorts, as well as presenting a shock hazard.
After performing alignment procedures, always exit the SERVICE menu
entirely (to the MAIN MENU) to properly save all changes. Failure to do so can
result in an alignment, or other, failure.
