■ 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 be-
tween broadcasting frequencies of any AM station.
The illustration shows the 9 kHz interval zones (re-
gions 1 and 3), and the 10 kHz interval zone (re-
gion 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 fac-
tory.
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.3Press 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 button and the MEMORY/
SET 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 button and the MEMORY/
SET 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.
Caution:
● When the unit is left for a few hours after the
span has been switched and AC power lead dis-
connected, 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.

*If the focus is disturbed, the process returns to step 1.
Other cautions
• TOC IL is not executed in the test mode.
• As for button operations other than those shown above, only the sound volume operation (with JOG) is accepted.
3. Tuner Test Mode (TEST 2)
1. Outline of tuner (radio) test mode
The tuner test mode is intended to store the adjustment and measurement frequencies in the preset memory CH without
frequency setting by adjusting personnel when the tuner section is adjusted in the production line.
2. Details of tuner test mode
When the power is turned on by using the "POWER" button while the "Volume/JOG Dial Selector" and "Volume Select"
buttons are held down in POWER OFF state, the frequency for adjustment and measurement of destination specified by the
AREA terminal is preset and stored in the preset memory CH. However, Ordinary 1 and Ordinary 2 are set to the designation
(destination selected by SPAN switching operation) set when the test mode is set. (As for frequencies to be preset and stored
for each destination, refer to item 3.)
The tuner test mode is started from preset No.1.
The operations of test mode are identical with the ordinary operations of TUNER function. However, FUNCTION switching
is invalid.
Since it is necessary to discard the content of preset memory when the tuner test mode is ended, "0000" or "1111" bits are
written in the memory to be checked in case of memory check (in case of initial setting) so that memory abnormality is detected
in case of initial setting so as to ensure memory initialization.
When the tuner test mode is turned on, the following indication lights for one second.
• The TUNER TEST2 mode is set as a result of Volume Select + POWER. -> IF AC is set to OFF in the TEST2 mode, the initial
state is restored.
When POWER is set to OFF, the memory of TEST2 mode is protected.
When the power is turned on again, the ordinary operation is enabled while the data is stored in the
memory (besides TUNER).
If AC OFF state is maintained in this state for about 1/2 day, start is executed in the initial state.
• To clear the whole memory, insert the AC cord, holding down MEMORY + PLAY.

• Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
