AM/FM interval (span)
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.
Before using the unit, be sure to set it for the AM tuning interval
(span) used in your area.
To check the tuning span currently selected:
1
Press the ON/STAND-BY button to turn the power on.
2
Press the FUNCTION button until "FM" or "AM" appears in
the display.
3
Press the BAND button to select the AM band.
● If "AM 531 kHz" is displayed, it means that the radio has been
adjusted for a 9 kHz span. If "AM 530 kHz" is displayed, it
means that the radio has been adjusted for a 10 kHz span.
To change from a 9 kHz AM (50 kHz FM) interval to a
10 kHz AM (100 kHz FM) interval:
1
Press the ON/STAND-BY button to enter the stand-by mode.
2
Hold down the BAND button and the ■ button for at least 4
seconds. Release the buttons when "AM SP 10 kHz" and "FM
SP 100 kHz" are displayed alternately.
● The unit will return to the clock display.
To return to a 9 kHz AM (50 kHz FM) interval:
1
Press the ON/STAND-BY button to enter the stand-by mode.
2
Hold down the BAND button and the ■ button for at least 4
seconds. Release the buttons when "AM SP 9 kHz" and "FM
SP 50 kHz" are displayed alternately.
● The unit will return to the clock display.
Cautions:
● When the unit is left for approximately 14 hours after the span
has been switched and AC power lead disconnected, it will be
automatically returned to a 9 kHz span. If this happens, set
the span again.
● When the span is switched, any stations that are memorised
will be cancelled.
