Using the eye shades
Look into the eyepiece sleeves and slide the interpupillary distance
adjustment seats a so that the visual fields of the two eyes coincide.
} By memorizing the user’s own interpupillary distance shown
by the interpupillary distance scale b on the center, optimum
interpupillary distance can be set by referring to this scale from the
next time.
Look into the right eyepiece sleeve with the right eye and adjust the
diopter adjustment ring c on the upper part of the eyepiece so that
the cross hairs are sharp.
Rotate the fine/coarse focusing knob d of the focusing unit or the
fine/coarse focusing knob f of the focus controller STM7-MCZ to
bring the specimen on the stage into focus.
For details of the focus controller STM7-MCZ, see "3-4 Focus controller
(Motorized frame only)" (page 28).
Look into the left eyepiece sleeve with the left eye and bring the
specimen in focus by rotating only the diopter adjustment ring e on
the upper part of the eyepiece. (In case of binocular system)

Observation Using Eyeglasses
Fold the eye shades to prevent damage due to contact between the
eyeglasses and eyepiece lenses.
Observation Without Using Eyeglasses
Extend the eye shades in the direction of the arrows to facilitate
observation by preventing penetration of incident light through the
space between the eyes and eyepiece lenses.
