Abstract
Systems (100) and methods (500) for controlling operations of an electronic device. The methods comprise: using a rotary knob having a single rotatable part to select a first circuit to perform operations of the electronic device during a first time and to select a second circuit to perform operations of the electronic device during a second time; and using the single rotatable part of the rotary knob to additionally change preset functions for the first circuit at the first time and a second circuit at the second time, where a degree of rotation of the single rotatable part corresponds to a desired preset function input selected from a plurality of possible preset function inputs.
