Is this a system that has been up & running? If so, all you have to do is move it, and all the associated 66M blocks and just reconnect the lines and the stations---and it should be programmed as it was before (if the CPU battery holds its programming). If you have to reprogram, then you will need to have the manual for this system. Its always a good thing to have the manual anyway. The system comes up in decent defaults---don't try to get too fancy with the initial programming. Work with ONE phone on the first port---- getting your lines to appear on it---then one by one get the other phones up. Good Luck.
