■ 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 rec\
over data fro m 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...

When replacing front-end (A1) of mother unit (X34-), or when
adding or replacing ROM correction (program correction with
ROM IC (IC10)), the following activities are required.
■  Overview
When replacing front-end (A1) in the model where ROM cor-
rection and security data have been written into E2PROM,
included in the front-end (A1) pack, the transfer function of the
E2PROM data itself in the replaced front-end (A1) is required....
