PURPOSE:To provide the transmitter-receiver which is used for a long time by relieving the load of a battery. CONSTITUTION:When a key is operated in the learning mode of a remote control signal in the case of M=3, reception processing is executed (S21) and a received remote control signal is stored in a RAM (S22). Then whether or not a carrier output time in one frame of the remote control signal is 60% or over is discriminated (S24). When the carrier output time is 60% or over, remote control data stored in the RAM are deleted and an error display is made (S25). Furthermore, in the transmission mode in the case of M=2, when a key is operated, the remote control signal stored in the RAM corresponding to the operated key is sent. |
