The International Telecommunication Union (ITU)
has established that member countries should
maintain either a 10 kHz or a 9 kHz interval between broadcasting frequencies of any AM station.
The illustration shows the 9 kHz interval zones (regions 1 and 3), and the 10 kHz interval zone (region 2).
This product is not equipped with a span selector.
However, it will be adjusted to 9 kHz AM interval
(50 kHz FM interval) when shipped from the factory.
Press the TUNER MEMORY button to set it.
● The unit will return back to the normal frequency
display.
Notes:
● If the backup memory batteries are not inserted
and the power is disconnected, it will be automatically returned to a 9 kHz span.
If this happens, insert the backup memory batteries first and set the span again.
● When the span is switched, any stations that are
memorised will be cancelled.
