ABSTRACT:
An electronic postage meter includes a settable mechanism for printing postage with electronic accounting circuits coupled to the printing mechanism and a value selection control circuit for controlling the value set on the printing mechanism. An audible alarm device is mounted within the meter housing and is connected to be controlled by the microcomputer. The audible alarm device is selectively energized by the microcomputer to alert the meter user of the existence of predetermined conditions. The value selection control circuit may include a winding which is adapted to be energized under control of the microcomputer to cause the value selection control circuit to operate to control the value to which the printing mechanism is set. The microcomputer is operable to energize the winding at a first frequency which will cause the audible alarm device to emit an audible sound but will not cause the winding to cause the value selection control circuit to operate to control the value to which the printing mechanism is set. The microcomputer is further operable to energize the winding at a second frequency which will cause the value selection control circuit to operate to control the value to which the printing mechanism is set but will not cause the audible alarm device to emit an appreciable audible sound.
