I Have One Customer using an KX-TDA600 system(Malaysia).They have one main cabinet & one expansion cabinet .The expansion Cabinet has one working ESLC16 card.Now they want to add 2 more ESLC16 cards. When I installed the cards the system came up with this error "Over card limitation".Why does it come up with this error.Can anyone help me.(I already checked with Panasonic, but untill now they have not seen nor heard of this error )
