摘要

The device has a signaling unit that is arranged in a receiving unit for converting the decoded signal sequence to an optical and/or acoustic output signal. An interface (45) is arranged in the receiving unit for coupling auxiliary modules e.g. a speech control module, an auxiliary receiving module (55) and/or auxiliary transmitting module for auxiliary functions. An interface (65) is attached to a transmitting unit and/or the receiving unit for external signal code programming.
