SERVICE PROCEDURES
1. Replacing the fuses
For
continued
protection
against
fire
hazard,
replace
only
with same type and same rating fuse.

In R724 Carbon resistor 1kQ
(Part No.417341024) is used.
In D711 Diode 1SS270A
(Part No.223205) is used.
— Worldwide model—
Worldwide models are equipped with a step band selector
switch. This switch is located on the back panel. This
switch is set to 9kHz (AM) at the factory,
but may have to be reset to 10kHz depending
on the area where the unit is used.

3. Memory preservation
This
unit
does
not
require
memory
preservation
batteries.
A
built-in
memory
power
back-up
system
preserves
contents
of
the
memory
during
power
failures
and
even
when
the
unit
is
unplugged.
The
unit
must
be
plugged
in
and
the
power
switch
turned
on
and
off
once
in
order
to
charge
the
back-up
system.
Note
that
since
this
is
not
a
permanent
memory
the
power
switch
must
be
tumed
on
and
off
a
few
times
each
month
to
keep
the
back-up
system
operative.
The
period
of
time
during
which
memory
contents
are
preserved
after
power
has
last
been
turned
off
varies
depending
on
climate
and
placement
of
the
unit.
On
the
average,
memory
contents
are
protected
over
a
period
of
3
to
4
weeks
(a
minimum
of
2
weeks)
after
the
last
time
power
has
been
tured
off.
This
period
is
shorter
when
the
unit
is
exposed
to
very
high
humidity
or
used
in
an
area
with
an
extremely
humid
climate.
4. Safety-check out
(Only U.S.A. model)
After
correcting
the
original
service
problem
perform
the
following
safety
check
before
releasing
the
set
to
the
customer.
Connect
the
insulating-resistance
tester
between
the
plug
of
power
supply
cord
and
terminal
GND
on
the
back
panel.
Specifications:
3.3
Mohm
+10%
at
500V.
5. Change of voltage
Worldwide
models
are
equipped
with
a
voltage
selector
to
conform
with
local
power
supplies.
This
switch
is
located
on
the
back
panel.
Be
sure
to
set
this
switch
to
match
the
voltage
of
the
power
supply
in
your
area
before
turning
the
power
switch
on.
This
switch
is
set
to
220V
at
the
factory.
Voltage
is
changed
by
sliding
the
groove
in
the
switch
with
the
screw-
driver
to
the
right
or
left.
Confirm
that
the
switch
has
been
moved
all
the
way
to
the
right
or
left
before
turning
the
power
switch
on.

Description
Connect to the 7.2 MHz crystal oscillator.
Chip enable terminal. Connect to the PLL terminal of microprocessor.
Serial clock input terminal. Connect to the CLOCK terminal of microprocessor.
Serial data input terminal. Connect to the DATA terminal of microprocessor.
Not used.
AUTO/MONO selection output terminal. “L” when AUTO.
FM band control output terminal. “L” when FM.
AM band control output terminal. “L” when AM.
AM local oscillator input terminal.
FM local oscillator terminal.
Power supply terminal for back-up.
Power supply terminal.
Charge pump output of the phase detector which constitutes the PLL. High level is output when the
divided local oscillator frequency is high than the reference frequency.
In the opposite case, low level is output. Floating occurs when the frequencies matched.
The output is applied to the variable capacitor diode in the local oscillator through the low pass
filters.
Ground terminal.
