steps
by which the tuned frequency decreases and increases 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, take this unit to an authorized Onkyo Service Center.
