PURPOSE:To prevent misoperation and system down by sending instructions out of a transmission part in predetermined order after an initial setting signal is supplied. CONSTITUTION:When a key 1 is operated, a signal indicating the program initial setting of an electronic exchange is supplied to a controller 2, which supplies as initial setting instruction to an instruction transmission part 3, so the instruction transmission part 3 sends out its internal stored instructions for the initial setting in the predetermined order. The instructions sent out of the instruction transmission part 3 are inputted to the controller 2 and then supplied to a central processor 4, so the central processor 4 performs the initial setting by a predetermined procedure, so no misoperation is performed unlike manual initial setting. |
