I installed a system recently; 403,with a 400 using 7 trunks and 16 4012d sets. when I put park keys on the sets they work on the 403 but not on the 400 .....Why?
Also If I put a DND key on the sets they work on the 403 but not on the 400. I must put a DND on and a DND off key on the sets that are on the 400 and the light will not work for the DND. Can anyone help me?
