Let us know after the power supply .

Also up above you mentioned prog 81 are you sure you were doing 81 out of the strata XII manual and not the dk as they are totally different?

This was:

Press CPU program button
Button 19 lights up
Press speaker
Enter 81xx (xx = ext number, 00 = all)
light all line keys (solid)
press Hold
display says: "Data Programmed"

repeat for 84xx, 89xx
