Embodiments are disclosed of methods and systems for providing information in a single FM tuner system. An example method according to the disclosure provides station information in a single FM tuner system, and comprises receiving radio data system (RDS) data/radio broadcast data system (RBDS) data by the single FM tuner system; extracting frequency information regarding receivable stations from the received RDS/RBDS data and displaying a list of the receivable frequencies; extracting additional information regarding the receivable stations from the received RDS/RBDS data, and displaying the extracted additional information regarding the receivable stations in correspondence with the respective receivable frequencies in the list. Further a single FM tuner system is provided for carrying out the method.

An electronic device is provided. The electronic device includes a first conductive layer, a second conductive layer that is formed to be opposite to the first conductive layer. The second conductive layer includes conductors that are electrically separated, and one or more photo-conductive members connected between the conductors. The electronic device further includes an insulating layer that is interposed between the first conductive layer and the second conductive layer, one or more light sources positioned to face the one or more photo-conductive members, and a control circuit. The control circuit outputs a specified light through the light source such that an electric conductivity of the photo-conductive member increases in response to a light, from among the photo-conductive members and some conductors are electrically connected with the photo-conductive member, and a capacitance value between the first conductive layer and the second conductive layer is changed.

An operation button includes: a body that is in a tubular shape; a top which has a light-transmitting portion and which is attached to the body at its one end; a plurality of legs that are provided at the other end of the body at intervals from each other in the circumferential direction; and a flange arranged between the one end and the other end of the body.

A control unit is provided with a selector and a plurality of value indicators. One of the value indicators provides a coarse indication of an existing value of an adjustable control quantity. The other value indicators are in another state, distinguishable from the value indicating state. A rotary adjustor provides a manual adjustment facility for a user. Selection of the selector puts the adjustable control quantity in an adjustment mode. In this adjustment mode, rotary actuation of the rotary adjustor allows adjustment of the control quantity. A new value of the control quantity is indicated by a change in the display states of the value indicators.
