I have a 84-cpa cordless phone adaptor from TMC. it used to work great... havent used it for a good year now, went to go re-connect it and now it does not work. when i connected my cordeless phone to the adaptor, I used to get a steady tone until i selected "1" or "2" to select the line and now I get nothing... just an open-ended line... anyone have a manual that might help me figure this out? even a discription of the unlabled dip switches would be of big help. thanks!
