ABSTRACT:
The present invention constitutes a display system for use in a telephone answering machine for indicating when messages are available for playback in the memory of the machine. The system comprises a display unit having a plurality of display modules which correspond operationally to various banks of memory within the answering machine and a microprocessor for providing control signals to the display modules. The display modules include mechanisms for generating light of a first color and for generating light of a second color in response to different logic states assumed by the control signals from the microprocessor. The display modules are controlled by the microprocessor to emit light of the first color when messages are resident in particular banks to which they correspond within the memory of the machine and emit light of a second color when such banks are empty.
