Hi,
We have running in our office a Meridian Norstar 616 phone system. The system has worked perfectly for years.
Now it seems if we experience a power cut we lose all the programming. Not only that but two of the incoming lines have become quiet. It is a fault of the CCU, plugging a phone directly into the BT line reveals all is ok.
I have been advised I can replace the 1F 5.5v memory capacitor inside the unit to cure the memory backup issue.
Has anyone any ideas what might be the cause of the quiet incoming lines on the mainboard? Has anyone experienced this before or willing to help me repair?
Thanks in advance,
Oliver
