When the flash memory (IC701) is replaced, be sure to perform the
BAD BLOCK check* and writing of the model code. If they are not
completed, the unit will not operate normally.
* BAD BLOCK check is to check the flash ROM memory
area (the BAD BLOCK area) where data cannot be
guaranteed. The resultant information of this check is stored
in the TOC-AREA so that the BAD BLOCK area should
not be used.

completed.
