I recently installed a 6x16 system and now I'm trying to adding a C6 call ID module. I only have two lines coming into the system and 4 handsets (M7310s). I made the following connects to the C6: Line 1 Pair (Blue/White & Blue) "T"s into the incoming CO Line 1, Line 2 Pair (Orange/White & Orange) "T"s into the incoming CO Line 2. I then connected a single pair of wires into the 2 screw terminals on the C6 and landed the other end of that pair to one of the unused station lines going to the 6x16. Can anyone tell me if that is correct? Also, do I need to turn on a feature on the handsets? Any help would be apprecited.
