(Embodiment 1) FIG. 1 is a configuration diagram of an indoor unit of an air conditioner and a remote controller. As shown in FIG. 1, the indoor unit of the air conditioner is a communication unit 1 and a control unit 2, and the remote control is a communication unit 3;
The control unit 4 is configured.

信するものである。A communication unit and a control unit for controlling the communication unit are provided in each of the indoor unit and the remote controller of the air conditioner. In a system in which the indoor unit and the remote controller perform two-way or one-way communication, the communication unit on the transmitter side A dummy signal is transmitted before data transmission, and the reception sensitivity of the receiver is adjusted to an appropriate level by the dummy signal. Therefore, when receiving a data signal, the reception sensitivity of the receiver is at an appropriate level, so that reception failure can be avoided. (Embodiment 2) Embodiment 2 is for transmitting a blank signal between data as a dummy signal before data transmission in a system for transmitting a plurality of data simultaneously.

め、確実なデータ受信が可能となる。FIG. 2 is a diagram showing the data structure transmitted from the transmitter. There is a blank signal between data 1 and data 2, and the blank signal is transmitted as a dummy signal before data transmission. On the receiver side, the reception sensitivity of the receiver side is set to an appropriate level by receiving the dummy signal, and when the dummy signal is received, it is determined that the signal is a blank signal, and the receiver immediately waits for a header signal, that is, the data signal reception wait state. Thus, reliable data reception becomes possible.
