■ 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
front-end (A1) replacement procedures and on the data to be transferred.
Procedure
While pressing and holding [1]

Description
When DC offset error is detected (when either one of capacitors is
leaking, or an improper connection or another error is detected)
When DC offset error is not detected (when none of capacitors leak,
no improper connection or other error is detected)
When improper connection or other DC offset errors are detected.
When improper connection or other DC offset errors are not detected.
When detecting improper connection or other DC offset errors, clears
detection data. (Clear E2PROM)
When detecting capacitor leak, provides information on the number
of capacitor leaks. (0~4)
When detecting capacitor leak, clears the number of capacitor leaks.
(Clear E2PROM)
