WorkTunes Hearing Protector is
preprogrammed using North American
frequency spacing between radio stations.
North America frequency spacing between
radio stations differs from frequency spacing
in Europe and Australia which is why
WorkTunes Hearing Protector comes
equipped with the option to choose the
frequency spacing you need based on
where you are located.
