Date Mar. 23, 1995A first carrier signal generator (15) generates a carrier signal (S1) at a first frequency to modulate a preset identification code (S). A second carrier signal generator (16) generates a carrier signal (S2) at a second frequency, distinct from the first frequency. A modulator (14) affixes the identification code (S) to the carrier signal (S2), and outputs the carrier signal (S2) to a light-emitting circuit (17). When a "smart" or "learning" remote controller, of the type that demodulates frequency, receives the identification code (S), the carrier signal (Sw) of the second frequency is demodulated at the first frequency, compressed and stored in memory. The carrier signal (S2) set at the second frequency can cause the memory capacity of the remote controller to overflow, thereby preventing the identification code (S) from being stored in the learning remote controller.
