■ 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  for details on front-
end (A1) replacement procedures and on the data to be transferred.

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.
This function in the above system configuration is used to al-
low for complete replacement of the front-end at any service
center.
■ Overview of specifications
Procedures for replacement are as follows: To install the
E2PROM to the mother unit (X34-), and replace front-end (A1)
with new front-end after copying the data in the E2PROM (such
as ROM correction data and other data) in the front-end (A1)
to the mother unit (X34-) by operating the system, and then
copy the data (such as ROM correction data and other data)
into the mother unit to the E2PROM of the front-end (A1), op-
erating the main body.
Tuner adjustment data was inserted during the tuner pack
manufacturing, and data will not be transferred because front-
end (A1) is built-in.
In addition, tuner adjustment data for new front-end (A1) is
supplied as a service part in which data was inserted.
■  Data to be copied

• Other data

■  Operation procedure
Operation procedure is different depending on the conditions.
Proceed with the appropriate operation procedure depending
on the specific condition.
1. In case of replacing front-end (A1) without an applicable
ROM correction.
2. In case of replacing front-end (A1) with an applicable ROM correction.
3. In case of applying new ROM correction at the same time when front-end (A1) is replaced. (No ROM correction has
been carried out.)
