AIR FMNone

AIR FMNone appears to refer to an unspecified or placeholder value associated with the AIR FM (possibly "Frequency Modulation") context, with "None" indicating the absence of a specific frequency or station. In practical terms, it might signify that no FM radio station has been assigned or is available in a particular setting. Understanding this term depends on the specific system or device context, but generally, it indicates the lack of an active FM frequency or station connection at that moment.
