upgrade must backup presets using the procedure in the VoicePrism
manual. These backed up presets may be uploaded to the unit with the
VoiceCraft card following installation of hardware and software.

The VoiceCraft upgrade card has both hardware and software
components. Software may be installed by either of two methods, by
