Mount
th
e body
onto
the
microscope
Remove the viewing head from the microscope.
Put
the
Model DO main body
onto
the
microscope in place
of
its viewing
head,
and fasten
them
with
the
mounti
ng ring.
(Take care
not
to
give any damage
to
the long, slim
tube
underneath
the
main
body,
when
you
insert it
into
the
opening
of
the
microscope.)
Fasten
the
body
to
the
microscope
at
your
preferable direction
with
the clamp knob.
(The
body
can
rotate
360°
.)
Attach
the
binocular heads
Attach
the
binocul
ar
heads
on
bot
h sides
of
the body.
Fasten the heads
to
the
body tightly
with
the
clamp
knobs
, when
the
eyepiece tubes
come
uppe
r
most
position.
(Before
their
attachme
nt, make sure each binocular head belongs
to
the
main
body,
for
there is a fea r
of
cutting
off
the marginal part
of
the view field, if a wrong
bino
cular head
is
attached.)

How
to Use
A. Adjust
th
e mechanical
tube
length
I.
First,
the
principal observer, looking
into
the
eyepiece, make
the
following procedures.
I) Bring
the
specimen into focus,
by
handling the coarse and fine
adjustment
handle
on
the
microscope.
2)
Fit
the interpupillary distance between
the
eyepieces
to
his eyes.
3)
Turn
the dioptric adju
stment
rings in accordance
with
the
interpupillary distance scale.
(W
ith
this, the mechanical
tube
le n
gth
will
be
adjusted
at
160mm.)
4)
Repeat
the
focusing procedures with
the
coarse
and
fine
adjustment
knob
of
the
micro-
scope, again.
(If
there is a
dioptric
difference between his eyes,
set
one
of
the dioptric
adjustment
rings
to
the
interpupillary scale,
and
the
other
dioptric ring must be focused at the speci-
men directly, looking at
it
through
the
eyepiece.
2.
Second,
the
sub-observer makes the following procedures.
I)
Adjust
the
interpupillary distance
to
his eyes.
2)
Fit
the
scale
of
the dioptric adjustment ring
to
that
of
the interpupillary distance.
Thus
,
the
mechanical
tube
length is
kept
I
60mm.
(If
he has a dioptric difference between his eyes, do the same procedures as stated in the principal
observer, paragraph 4).
If this procedure fails
to
fit the sub-observer's diopter, turn the dioptric adjust-
ment ring on his side freely to well fit to his diopter.)
