	If you are on a call and the display suddenly
	shows “Discovering...,” the network connection
	between the telephone and the call server was
	interrupted, but your call stayed connected. The
	telephone automatically starts to re-register with
	the call server, but until re-registration succeeds,
	you do not have access to switch features and
	functionality such as Transfer, or to
	administered Feature buttons.
	If you cannot resolve the problem based on the
	message received, contact your System
	Administrator for resolution.

	telephone idle (on-hook), press and release the
	Mute button. Then press the following numbers
	on the dialpad: 8 3 7 8 # (which stands for
	TEST). The display should indicate the self-test
	has started, then report if the test was
	successful or failed. If nothing appears on the
	display, and the phone is receiving power, your
	phone might need to be replaced.
	If these suggested solutions do not resolve the
	problem, reset or power cycle the phone with
	your System Administrator’s assistance.
