■ ROM data transfer
When replacing front-end (A1), this function is used to transfer E2PROM data (ROM correction, security and other data) to front-end (A1) to
E2PROM of to mother unit (X34-), used for saving data, and, after completing replacement of front-end (A1), to recover data from the E2PROM
of the mother unit (X34-), and for saving data to the new front-end (A1). Refer to "ROM data transfer processes" on the next page for details on
