Hi guys, I am replacing 2 of my old Teltronics 10 button non display phones and i'm running into a problem.

The phones I bought were already programmed to another system and when I plug them in I guess they are just sticking to their old programming instead of my extension number.

Is there a way to reset the device? When I had new replacements all I had to do was plug them in and press 7,I think, its been a while, and the phone picked up the programming that the other had.

I am simply replacing and old station with this one, so it will take over the extension number of the old phone.

There is not much literature out there that I could find, I guess this system died well before the internet :-/

Thanks in advance!
