The New Call window can be reduced to a smaller window by pressing the up key of the navigation cluster so that the user can get a quick view of the home screen. This feature facilitates a quick view to let the user use the PLK's configured with busy lamp field, speed-dial, or busy lamp field+speed-dial combos to initiate a New Call, Conference, Transfer or any other call feature which open up the New Call window.
The user can only see line keys numbered 2, 3, 4, 5, 7, 8, 9, and 10. The reduced window is restored to its original size:
If the user hits the down key on the navigation cluster.
If 5 seconds have elapsed since it has been reduced.
If the user presses any button on the device excluding the up key on Navigation cluster.
