I have a customer with an old Norstar 616 with DR2. The auxillary ringer contacts don't work anymore. If I manually apply a short to the contacts, the night ringer will ring.
The programming is set for night service, auxillary ringing per line, etc.
Is there anything I can do inside the cabinet (yes, inside the box that says "no user serviceable parts inside") to try to get this thing to operate again? Otherwise I guess they're looking at a new ksu.
Thanks. Jim
