Alignment Procedure
6.1
PC Tune
PC Tune software is used to perform alignment procedures on the EFJohnson 5100 series
portable radios.
Perform alignment procedures if repairs or adjustments are made that can affect the
factory alignment. All adjustments are set digitally using the computer. It is not necessary
to disassemble the transceiver to access adjustment points. In addition, audio test signals
are generated internally, so an audio generator is not required.
To verify radio operation, perform the Digital Performance Tests and the Analog
Performance Tests in the PC Tune manual included on the PC Tune CD.
