Mitsubishi EDM DWC-90H Parameters

I have mitsubishi EDM DWC-90H. I think its parameter become corrupted.Could any one help me.It start normally. every cassette loads correctly. there is no alarm. but the system ready button do not operate or active. I check every hardware and card they are okey.After all i think its system parameters are not okey because it show nothing in optional parameter no.1 and no.2 blank. could any one tell me the system parameters so that i load them and compare the already parameters.
