This software is designed for standard non-"S" models (e.g., ) and serves two major functions:

A frequently overlooked prerequisite is radio power. The radio must be with a fully charged battery (for portable units) before attempting any programming operation. A low battery during the cloning process can cause communication errors or data corruption.
