PURPOSE:To add a remote control function to a slave device, and to expand a telecontrol function by switching the processing content of a processing means according to the setting of a changeover switch. CONSTITUTION:A TEL/RC mode changeover switch 66 is provided on a slave device 62, and the processing content of a CPU 24 is switched according to the setting. Thus, a remote control function can be added to the slave device 62 without making a device constitution large and complicated. In the telecontrol, the data of the telecontrol are transmitted from a master device, and the CPU 42 of the slave device 62 operates the remote control function. Thus, the object of the telecontrol can be expanded not only to equipments at the surrounding of the master device but also to the equipments at the surrounding of the slave device 62.
