The tuning steps by which the tuned frequency increases/decreases have been set at the factory to the proper value for the area where each
unit is to be sold. If you use the unit in a country where a different tuning step is required or if the broadcast frequencies in your country
change so that you can not tune in radio stations precisely, take this unit to your Onkyo authorized service center.
