Hello and thanks in advance, I know this forum not is specially for talk about intercoms but I don't found one forum specially for this. Please help me. I have a Aiphone Intercom System ( GT-MK central and three GT-1D ) and for reasons I unknown, the intercoms were misconfigured, I try manually configuration but GT-MK central showed the following error: Error ID# Entry. I read on a website that have to reset before but I don't know how make this. Regards and sorry if I can't post this here.
