I work at a church and school where we have two DX-80 systems (one at the school, one in our rectory). The VM in the rectory has quit working. Symptoms include no answer when VM button is pressed on DET and line goes quiet, can't transfer to VM etc.

I don't have Keylink (but I do have and have used PC-DBA). I'm also not a phone tech but have extensive experience with board level troubleshooting and repair of electronics. I decided to check the voltages at the via's in the upper left corner of the VM-II board because of the easy access. All were good except the 2.5v one. It was zero. The board is also beeping from the sounder. Sounds like Morse code (which I know cuz I'm a ham) but I scoured the web and the manuals for any reference to decode this, to no avail. For the time being, I'll assume this is the source of my problem. I sourced another VM-II board and have the following question.

I'd like to swap my existing CF card into the new VM card, configure the jumpers the same, and install it. Assuming my existing CF card is not trashed, should the system come back with the VM settings and recordings in tact? Or, am I missing a needed step(s) that requires Keylink?


[I also want to note that I have contacted a local telecom company that services Comdial, but multiple VMs have gone unanswered. Hence why I'm trying to get it up and running myself as my stakeholders are getting a bit antsy!]
