Hi there
to trasfer to whole memory of the M3904 set, you need a CTIA Catridge and the Personal Directory PC Utility Software.
Personal Directory PC Utility
The Personal Directory PC Utility provides a faster, easier way to create or modify
the Personal Directory on the M3904. You can enter names and numbers into a
directory file on your PC, and download the file directly from the PC to the M3904
through a serial port connection. You can also upload the Personal Directory from
the M3904 to your PC so that you can modify the directory. The PC and the
M3904 are connected using the Personal Directory PC Utility Cartridge. The Computer Telephony Integration Adapter (CTIA) may also be used to connect the PC and the M3904 when used with the optional Personal Directory PC Utility
software.
Bye
