Introduction

Section1
This document describes the use of PC Tune software for tuning and performance tests of
EFJohnson Technologies 5100 series portable radios.
With PC Tune, 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 no audio generator is required.
The sections that follow contain details of PC Tune setup and use as follows:

• Guidelines for use of PC Tune

1.1 Guidelines for Use of PC Tune
PC Tune is intended for use by certified maintenance technicians when radio tuning and
testing outside the factory becomes necessary.
The testing and tuning performed at the factory by EFJohnson Technologies on your
radios before you received them is generally more precise than that which can be done in
the field. For this reason, PC Tune should not often be used in the field.
You should only use PC Tune for out-of-factory testing and tuning under certain
circumstances. Examples are:
• Hardware replacement that requires radio retuning
