You'll also need to, from the main screen....
Press the call button
In the text field type ##000000
Press the call button again
Edit the top line so that it has your phone # in it
They say not to edit the 2nd line but I did it anyway. That was 3 months ago and no issues yet.
Press the ? key and click save
When you try to close out, the phone will want to reset itself
Allow it
