Abstract: A remote controller 10 sets, in step S1, a period of time Tx in which a reception mode is maintained after an instruction is transmitted. A generated instruction is transmitted to a communication module 20 (in step S3). The communication module 20 converts the received instruction into a control signal and transmits the signal to an electronic apparatus 30 (in step S4). After a process is executed in response to an instruction, the electronic apparatus 30 outputs information to be returned to the remote controller 10 to the communication module 20 (in step S5). The communication module 20 transmits information (in step S6). The information is received within the period of time Tx after the instruction is transmitted. Thereafter, the reception mode is cancelled (in step S7). After the reception mode is cancelled, the remote controller 10 returns to a sleep mode and operates with the minimum power.

Abstract: The risk of a third party able to conduct pairing is reduced, and operation is also made simple. In S1 the radio wave strength of a pairing signal received first is measured and retained. In S2 the message “Come a little closer” is displayed. In S4 it is determined from the radio wave strength whether or not the current distance is within a given range with respect to an instructed distance. In S5 it is determined whether or not the number of determinations in which the current distance is determined to be within the given range has reached a set number of determinations. In a second determination the message “Now move away a little” is displayed. If the second determination becomes positive, S6 (pairing registration) is performed.

Abstract: A wireless communication system includes a transmitting side equipped with a microcomputer for control, for transmitting data and also includes a receiving side for receiving data. To prevent the receiving side from receiving identical data more than once, a sequence number is automatically incremented every time a frame of transmit data is transmitted. The sequence number is transmitted together with the data. The next process is performed if it is determined that transmission is correctly performed, or the data is transmitted again without incrementing the sequence number if it is determined that the transmission is not correctly performed. The sequence number is returned to an initial value when the microcomputer for control is reset, and dummy data is transmitted together with the initial value immediately after a reset. The data is transmitted together with an incremented sequence number after transmission of the dummy data.
