where and when are these used. how can you verify them once configured?
any takers for this simple '5'
Those buttons can be used via the abbreviated dial feature. If you program in a number on the page above, then just hit the number on the list of the number you want to dial BEFORE you go off hook. One of the softkeys on the display will change to AbbrDial. If you hit that AbbrDial softkey it will dial the number that you programed in.
list number 1 is 555-1212, you would hit 1 abbrdial and pick up the phone. The phone will then dial 555-1212.
Hope this is clear, it's easier to do then to explain!
