Service Adjustment Data Table
These initial values are the reference data written from the
CPU ROM to memory IC when replaced new memory IC. The
adjustment items indicated with “ ✻” are required to readjust
following to the “ Electrical adjustments”. Other items should
be used with the initial data value.
