Adjusting the interpupillary distance
The interpupillary distance adjustment is to adjust the distance between
two eyepieces according to the distance between your eyes. This makes
it possible to observe a single image and to reduce eye strain during
observation.
Keep the right and left eyepieces horizontally. While looking through
the eyepieces, move the binocular portion either in
a
or
b
direction
until the right and left fields of view coincide completely. The value
shown by the indicator (protrusion)
c
on the left side eyepiece sleeve
represents your interpupillary distance.
· Note your interpupillary distance so that it can be easily
adjusted next time.
· You can adjust your interpupillary distance by moving the
binocular portion either to upper or lower side. Select the upper
side or the lower side according to your observation posture.

Using the pre-focusing lever
The pre-focusing lever prevents the specimen from being damaged by
collision between the specimen and objective.
After bringing the specimen into focus with the high magnification
objective, rotate the pre-focusing lever
a
in the arrow direction until
it stops.
To provide a certain margin for focusing range, rotate the pre-focusing
lever
a
by about half turn in the direction opposite to the arrow
direction from the stopped position.

If the pre-focusing lever is not positioned appropriately,
the stage may not rise and the specimen may not be
focused. In this case, adjust the pre-focusing lever
position again.
It is recommended to use the pre-focusing lever to prevent the
specimen from damage, but if you do not use the pre-focusing
lever, rotate the pre-focusing lever in the direction opposite to
the arrow direction until it stops.
