PURPOSE:To eliminate a misoperation in case of turning on a main power source, and to operate exactly a switch by constituting so that it can be decided in a remote device side that a body device is on the way of its rise. CONSTITUTION:In a remote device 2, when a switch 27 is operated in order to turn on a main power source 9 of a body device 1, a power source on/off command signal is generated. In the body device 1, the power source on/off command signal is received by a power source control part 7 being in an operating state by an auxiliary power source 6. When a program start becomes possible, it is informed to the remote device 2 that the body device 1 rises normally. Thereafter, a communication between the body device 1 and the remote device 2 is executed by a polling form. When a response from the body device 1 is received, the remote device 2 turns on a state lamp 31 in order to show that the body device 1 is in a sendable and receivable state, and sets a time TM2 for monitoring a polling interval. |
