This switch is also used to shift the reception frequency of the unit in accordance with the
transmission frequency of the broadcasting station.
When this button is pressed slightly longer, the reception frequency decreases by 0.002 MHz
(2 kHz). So, for example, to receive 153 kHz, tune to 155 kHz, and then press this button.
In order to return to the original frequency indication, press this button again.

mw HOW TO PRESET RADIO BROADCAST FREQUENCIES
This unit can be used to preset as many as 16 radio broadcast e Memory presetting
frequencies: 8 FM and 8 AM (MW/LW). After broadcast
frequencies have been preset as described below, any desired
station can be quickly and easily selected by simply touching
one button.
Automatic memory presetting

Description of terminal
—>/ sane FM Signal
aaaep / seee> AM Signal
Segment signal output terminal for display.
Common signal output terminal connected to LCD. Output is delivered in 3 values of ground,
1/2VDD and VDD (at 5ms intervals) in a period of 50 Hz.
The segment turns ON when the difference in voltage is + Vpp between these terminals and
LCD1 ~LCD23.
Power supply terminal of device. Voltage of 5V + 10% is supplied during operation of device.
DD
= To hold the internal data memory (RAM), the voltage can be decreased to 2.5V.
33 VDD Note: Pins 7 and 33 are connected inside the chip. It is unnecessary to supply voltage to the ai
pins. C7
Input is local oscillator output (VCO) in a range of 10 ~ 130 MHz (0.3Vp-p, min.).
8 EM There are 1/2 fixed frequency division prescaler and 2-step (1/32, 1/33) prescaler internally.
Therefore, when deciding the frequency dividing value of programmable divider, it must be
decided from the frequency obtained by halving the local oscillator output (VCO).
Input is local oscillator output (VCO) in a range of 0.5 ~ 20 MHz (0.1Vp-p, min.).
9 AM When the mode is shifted to FM, the AM terminal voltage automatically becomes the supply
voltage of device.
; MW ON
10 GND Ground terminal. LW-—OFF
a a (re)
11 E01 When the divided oscillator frequency is higher than the standard frequency, H-level output US
is delivered from these terminals.
12 E02 When it is lower, L-level (OV) output is delivered. When they coincide, it results in floating.
+ a
Device selection signal input terminal. The signal level should be high when the device is
13 CE operated, and low when not operated.
With this terminal shifted to low level, LCD (liquid crystal display) turns off and the memory
is held.
14 NC Not used in this unit.
15 x1
Connecting terminal for crystal oscillator. The crystal connected is 4.5 MHz.
16 X2
7 A3 (SD) Terminal to put in stop signal during auto tuning. The voltage is 5V with broadcast received,
and OV without broadcast received.
This is the interrupt demand signal input terminal. The signal from the control input terminal
18 A2 (INT) is put into this terminal, demanding for interruption, then the flow of program will be
unconditionally shifted to the address No. 1.

Components identified by AV mark have special characteristics
important for safety. When replacing any of these components, use
only manufacturer's specified aprts.
Note 2:
e Use of ceramic filters in pairs
The ceramic filters (CF 101, CF 102) for FM-IF circuit are available in three ranks.
For this machine, be usre to use the ceramics of the same rank in a pair.
At rapairing and replacement, pay close attention to the diodes (D901, D902)
for use as different diodes must be used depending on each rank of the ceramic
filters.
