Sounds like you may need a different manual. The DK16 manual is more towards the DK280 and the DK16e manual would be based more towards the DK424. If you page up and look at The Bunnie's post you'll see it is pretty much accurate or at least enough to get you going on the programming. It should be PGM *29 like Bunnie said' and depnding on which port has the DADM on it, it will be that port number +1 in the program. Then # and you should be able to hit the corresponding LED's ( on the 20 button phone ). Then you should be able to put the extensions on the keys by using thier port numbers. Like I said Bunnie's post is informative enough to do this.

btw, did the message light go out?
