The tuning steps by which the tuned frequency changes on each band have been set at the factory to the proper value for the country 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, contact your authorized Onkyo Service Center.
