Whenever
you
remove
the
viewer
from
the
photographic
unit,
be
sure
to
install
the
cap.
2.
Insert
a
finder
eyepiece
into
the
right
eyepiece
sleeve.
3.
The
finder
eyepiece
has
a
built-in
focusing
lens
with
four
masks,
and
the
focus
is
practically
the
same
for
the
focusing
lens
and
the
camera
film
plane.
The
masks
indicate
the
areas
covered,
and
the
numerais
next
to
the
masks
correspond
to
the
magnification
of
the
photo
eyepiece.
Different
finder
eyepieces
are
available
for
different
cameras.
Select
the
type
that
is
appropriate
for
the
camera
being
used,
4.
Because
of
the
great
depth
of
focus
of
1X
to
4X
objectives,
use
of
the
illuminated
focusing
telescope
(U-FT)
is
recommended
for
accurate
focusing.
*
Focusing
is
easier
using
the
focusing
telescope
of
the
camera
unit
than
using
the
finder
eyepiece.
