METHOD OF ADJUSTMENT
When
making
adjustments,
be
sure
the
power
supply
is
at
the
rated
voltage
and
the
room
air
is in
normal
condition
with
respect
to
temperature
and
humidity.
Secondary Voltage Adjustment
Adjust
VR801
so
that
the
voltage
across
the
both
ends
of
C802
reads
23.4
+
0.2
V
in
case
4
ohms

Idling Current Adjustment
Under
the
state
of
power
voltage
14.4
V
and
no
load,
connect
DIGITAL

to
R630A,
630B,

per
the

Figure,
within 30
~
40
seconds after
turning
power
on,
adjust
VR606A,
B,
C,
D,
E,
F
so
that
the
voltage
acness
the
both
ends
of
the resistor
is
read 3
mV
~
15
mV
(10
mA~
50
mA).
