The digital display module allows the search and display of the neighbors list (electronic directory) by means of the navigation buttons (arrow keys), in addition to informing about the status of the communication. The call to the home can be made in two ways: (1) by entering the corresponding code assigned to the home + the "bell" key, (2) by searching the user's electronic directory (navigation buttons) and once found by pressing the "bell" key.
