ABSTRACT:
A control device which is suitable for use with electronic apparatus is used to scan a range of signal or data values, such as a frequency spectrum, and to cease scanning when a selected parameter is found. The scanning operation is driven by a d.c. ironless motor which, once it has been initially spun by hand, continues to rotate until the selected parameter is detected.
