Hello, I have a Toshiba DK-40i System. Last week I lost all the Programming to the Door Box, DDCB/MDFB.

Have not programmed this system in Many Years, But I figured it out through the Manual and got all 6 Phones to Ring and Flash when outside Door Box is Depressed.

Only Problem is since doing this, all of the DSS Keys are every Phone do not work. Went back into Programming and I see the Buttons are still Programming for Various Rooms,in the House But the Buttons are Dead. These Buttons were originally Programming through Program 39.

I think it is only something Minor Missing here, But I leave it up to you more active Telephone Programmers to tell me what I am Missing.

Would Appreciate Help, Thanks
