Adjustment
Ra2:
The
volume
to
determine
the
amount
of
change
per
EV
of
aperture
and
ASA.
Making
the
voltage
of
Vreg
—
VI
agree
with
226±lmV.
R3:
This
is
to
change
the
lighting
width
of
LED.
Fixed
resistance
is
soldered
to
it,
being
selected
in
the
range
from
6kohms
to
lOkohms.
Standard
value:
(1)
+
and
green
(•)
are
lit,
Abt,
0.8
EV
(2)
Only
green
(•)
is
lit.
Ditto
(3)
Green
{•)
and—are
lit
Ditto
The
standard
resistance
is
8.2
kohms;
however,
when
it
is
intended
to
expand
each
lighting
width,
the
resistance
is
decreased,
and
when
it
is
intended
to
narrow
the
width,
the
resistance
is
increased.
However,
it
impossible
to
expand
or
narrow
•
(green)
only.
Ral:
This
is
semi-fixed
resistance
for
adjusting
the
amount
of
light.
With
a
flat
light
source,
and
setting
aperture,
ASA
and
shutter
speed
as
properly
selected,
adjustment
should
be
made
so
that
only
green
LED
(•)
is
lit.
Repairing
Method
1.
Not
lit
(LED)
No
current
flows
to
AMP
due
to
contact
failure
of
EC
switch
or
disconnection
of
white
lead
wire.
2.
OVER
is
left
lit
(1)
The
voltage
of
RF
is
high,
the
sam
as
Vreg
without
any
change.
(Because
of
wiring
or
R2,
Ra2
or
D
is
out
of
order.)
(2)
The
voltage
of
Rasa
is
high,
the
same
as
Vreg
without
any
change.
(Because
of
the
same
as
above.)
(3)
Vadj
is
low.
(The
leg
of
C4
shorts
to
the
body.)
3.
UNDER
is
left
lit
With
respect
to
the
phenomenon,
reverse
to
para.
2.
Short
circuits
of
RF,
Rasa,
Ral,
etc,
including
failure
in
SPD.
4.
One
or
2
of
3
LED's
go
on
and
off,
but
the
remainder
do
not
go
on.
(1)
Disconnection
of
soldered
legs
of
LED.
(2)
Disconnection
of
R5
through
R7.
(3)
Defective
LED.
Apply
R-range
of
tester
to
(+)
and
LED
(—)
sides,
and
check
whether
LED's
are
lit.
5.
The
lighting
width
is
broad.
Make
R3
greater,
(8.2
kohms
to
10
kohms)
6.
The
lighting
width
of
Green
(•)
is
narrow.
Make
R3
less,
(8.2
kohms
to
5.6
kohms)
7.
GREEN
is
not
lit.
UNDER
is
lit
directly
from
OVER
passing
over
GREEN.
1C
is
defective,
and
AMP
should
be
replaced.
Winding
Mechanism
•
The
A-S'M-set
lever
under
the
body
moves
to
the
spool
side
by
means
of
the
winding
lever
(147651),
and
sets
the
shutter
and
the
mirror
at
the
same
time,
•
Using
cocking
arm
fixer
Ass'y
(066616),
the
winding
can
be
made
away
from
.the
set
cam
fixer
(147610)
together
with
SR
lock
lever
(147439)
until
the
winding
is
made
halfway.
The
external
circum¬
ference
of
the
set
cam
clamp
is
used
in
the
middle
of
winding
so
that
the
shutter
release
shaft
is
con¬
structed
so
as
for
the
release
not
to
descent
in
the
course
of
winding
operation.
•
The
A-gear
stopper
pluges
in
the
A-gear
about
0,2mm
immediately
before
the
winding
stops,
and
then
the
check
pawl
is
released
from
the
set
cam
plate.
Adjusting
method
of
A-gear
stopper
Rotate
the
A-gear
stopper
shaft
(eccentric
screw)
(147618)
to
create
an
allowance
of
0.2mm.
Adjusting
method
of
check
pawl
Loosen
the
screw
(61814024)
and
make
the
check
anti-rewind
claw
collar
(147637)
(eccentric
colar)
rotate
for
adjustment
