When one of “1” to “10” keys is pushed, the data
of the corresponding position is read out of the
memory so that the desired station is tuned in.
The currently selected station is stored as lastly

When one of “1

corresponding position is displayed on LED. But
the data in the memory remains as it is.
Not operative.
When FT(+) or
key is pushed, APT is turned
off and the unit performs a sweeping of tuning
voltage. And when the key is touched off, the data
of tuning voltage is written in the memory.
Within 2 seconds after “10” key has been pushed,
when one of “I” to “6” keys is pushed, one of
to “16” positions is displayed and tuned in;
when one of “7” to “IO” keys is, however,
pushed, one of

Within 2 seconds after “10” key has been pushed,
when one of “1” to “6” keys is pushed, one of
“11” to “16” positions is displayed but not tuned
in since the data in the memory is kept as it is.
6. Tuning operation
When one of “1” to “IO” keys is pushed in the normal
mode, the corresponding data is read out of the EA
ROM so that the band output and tuning voltage are set
up to allow the unit to tune in the desired station. Then
the currently tuned in station is stored as a lastly
selected position in the specified address of EA ROM.
During the tuning operation, AFT output and MUTE
output are caused in the following timing.

1. Oscillation principle
(1) When the power switch is turned on, a current
is
applied to the base of TR5.
(2) Then, a current lc=hfe.ls, is applied to the collector
of TR5.
(3) The current
available at the collector of TR5
causes a voltage (feedback voltage of the same
polarity) at
(4) As the feedback voltage is given, a current
available at pin @ of
is allowed to run through
0705 and R711 and enter the base of TR5. When the
feedback voltage increases to more than the specified level, TR5 starts its oscillation.
(5) As the voltage at the collector of TR5 increases to
its saturation point, a reverse bias is applied to its
base to interrupt the oscillation.
(6) When the oscillation of TR5 is stopped, the energy
stored in
is discharged through the secondary
winding N4.
(7) Then there is caused a voltage (of the reverse
polarity) at
and N2 to turn on TR5 again.
Thereafter, the process is repeated for TR5 to
perform the oscillation continuously.
2. Operational principle of error amplifier
(1) The voltage which is induced at N3 winding is DC
rectified to produce a control voltage (between pins
The control voltage available at N3 is highly correlative with the output voltage of N4 because both N3
and N4 are electrically coupled with each other.
(2) Variation of the control voltage is detected by TRl
and
ec e voltage increases, it is amplified by
t d
TR2 and TR3 so that the current at the base of TR5
is bypassed.
(4) Then the current at the collector of TR5
limited to
the smallest.
(5) Accordingly, the pulse width is controlled to decide
the duration where TR5 is kept turned on.
3. Over-current protector circuit
(1) An over-current
is applied to TR4. With TR4
turned on, the current at the base of TR5 is so
reduced that TR5 will eventually stop the oscillation.

How to prevent
from damages due to static elec-
tricity
1.
When replacing or handling the IC, be sure to put on
your wrist a metal ring (earth ring) that is connected
to ground.
Avoid touching the IC directly by hand as much as
possible.
For the soldering iron and other jigs in use, be sure
to connect them to ground so that their potential is
the same as that of the PWB and/or IC.
The PWB cannot be connected to ground in some
condition although you attempt to attach the IC to
that PWB. In this case, be sure to keep the PWB at the
same potential as ground by touching it by your
hand on which a metal ring
put.
When handling the IC, it
recommended for you to
wear such clothes as not causing static electricity;
the ones of wool, silk or synthetic fiber should be
avoided. This is important in particular when handling the IC in a dry environment.
