The controller is for providing the alarm sound instead of the broadcasting sound at preset time. The controller contains the program comprising; (a) alarm and present time input routine storing each time at a memory, and (b) time detection routine providing an alarm pulse signal (APS1) from an alarm signal output terminal (AM0) of a microprocessor (4) after providing a main power supplying signal from an output terminal (M0) when the preset and present time coincides. The time detection routine, is repeated until the release key is input. |
