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.

1. When the power is turned on after the flash memory (IC701) is

replaced, the BAD BLOCK check starts automatically and the
 OPR  (D701) lights in orange.

2. In about 30 seconds after start of the check, the  OPR  (D701)

changes the color to green indicating that the check is
completed.
