ABSTRACT:
A control circuit of a remote controller includes a CPU, the CPU having a data memory adapted to store signal codes of different electric apparatuses. A procedure table memory adapted to record key switch functions of different electric apparatuses is included. A computing element is provided for sequencing through a plurality of the stored signal codes. A search interruption is included that is adapted to interrupt the sequential output of the signal codes when an output code is in conformity with a selected function of a particular electric apparatus. An emission output device is coupled to the CPU to transmit the signal codes to the electric apparatus.
