PROBLEM TO BE SOLVED: To solve the problem raised by the conventional communication system for air conditioner which adjusts the reception sensitivity of a receiver by means of an AGC circuit while the receiver receives transmitted signals when the system transmits and receives signals that the reception sensitivity of the receiver does not reach an appropriate level and data reception is failed, because the reception sensitivity of the receiver is adjusted after the receiver starts to receive data. SOLUTION: A communication system for air conditioner transmits a dummy signal from a transmitter-side communication section before transmitting data and, in addition, simultaneously transmits a plurality of data. The system transmits a blank signal interposed between the data as the dummy signal before transmitting the data. |
