Each memory displayed in LSI_NG can be checked by the following Read and Write method
to the arbitrary addresses individually.
1) Connect a target unit with PC like the LSI_NG check method, start Hyper Terminal, and set up a communication setting.
2) Only when the unit turns on, connect TP1065 (XCHK) on a MAIN ASSY B side to GND, and then turn on the unit,
