■ 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:

Press the ON/STAND-BY button to turn the

power on.

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:

Press the ON/STAND-BY button to enter the

stand-by mode.

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:

Press the ON/STAND-BY button to enter the

stand-by mode.

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.

The current time and timer time are set in the following procedure to perform the timer playback.

1.Set the current time to 1:00, set the timer to ON time 1:02, set the function to Tape, and set volume STEP 8. One minute is counted as one second, and the timer playback operation is performed. The fade-in (when playback is started) is executed at a rate of one step for 0.5 sec. After completion of fade-in the fade-out is executed at a rate of one step for 0.5 sec (WAIT 1 sec inserted). After completion of fade-out the power is turned off (after WAIT 1 sec), and the mode is changed to the standby mode.

The indication during operation is the same as that of ordinary timer operation.

6. LCD Test Mode (TEST 5)

When the LCD test mode is set, all the LCD segments are lighted. After that the indication is changed as follows according to the "PLAY" button input.
