PURPOSE:To inhibit or restore easily a buzzer function by setting a buzzer inhibition area in a nonvolatile memory. CONSTITUTION:When the buzzer function is inhibited, a diagnostic switch provided on a console 18 is turned on to set the diagnostic mode, and a preliminarily determined number is inputted with a cooy number setting ten-key provided on the console 18. As the result, a program which accesses a nonvolatile memory 19f is called, and a byte of the buzzer function inhibiting area set in the nonvolatile memory 19f is set to level ''1'', and a buzzer function inhibiting instruction is set. When the buzzer function is restored, a preliminarily determined key number is inputted with the ten-key to set the byte of the buzzer function inhibiting area to level ''0'', and the buzzer function inhibiting instruction is reset. |
