AM/FM Interval (span)
The International Telecommunication Union (ITU) has estab-
lished 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
Set the ON/STAND-BY button on the main unit to ON.
2
Press the TUNER (BAND) button until "FM" or "AM" ap-
pears in the display.
3
Press the TUNER (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 dis-
played, 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 on the remote control
to enter the stand-by mode.
2
Hold down the TUNER (BAND) button and the ENTER
button for at least 4 seconds. Release the buttons when
"AM SP 10 kHz" and "FM SP 100 kHz" are displayed
alternately.
To return to a 9 kHz AM (50 kHz FM) interval:
1
Press the ON/STAND-BY button on the remote control
to enter the stand-by mode.
2
Hold down the TUNER (BAND) button and the ENTER
button for at least 4 seconds. Release the buttons when
"AM SP 9 kHz" and "FM SP 50 kHz" are displayed al-
ternately.
Caution:
When the unit is left for a few hours after the span has
been switched and AC power lead disconnected, it will
be automatically returned to a 9 kHz span. If this hap-
pens, set the span again.
When the span is switched, any stations that are
memorised will be cancelled.
