KDC39xx series devices have a memory of numbers that tried to establish feedback
communication unsuccessfully. After unsuccessful connection attempt, the cassettes participating
in the feedback communication (parameter 250) will display the last number from which the
connection was attempted. Then you can establish a connection with the premises using a button

memory from the feedback communication, pressing the button
will switch the cassette
between idle state and display of the last number. Deletion of the number from memory takes
place after making a call using the button
