Using the Eye Shades
(Fig. 10)
When Wearing Eyeglasses
Use with the eye shades in the normal, folded-down position. This will
prevent the eyeglasses from being scratched.
When Not Wearing Eyeglasses
Extend the folded eye shades in the direction of the arrow to prevent
extraneous light from entering between the eyepieces and eyes.

Using the Eyepiece Micrometer Disk
(Figs. 11 & 12)
}When the WHN10X-H (or WHN10X) eyepieces are used, an eyepiece
micrometer disk can be inserted in one of them. When the eyepiece
does not have a diopter adjustment mechanism, however, it is hard to
focus on the micrometer disk if the operator has poor eyesight. Should
that be the case adjust the focus with eyeglasses on.
To insert an eyepiece micrometer disk in the CROSS WHN10X, replace
the built-in cross with the eyepiece micrometer disk.
Use an eyepiece micrometer disk with a diameter of 24 mm and
thickness of 1.5 mm.
Following Fig. 11, turn the built-in micrometer-mounting frame
2
counter-
clockwise to remove it from the eyepiece and place a micrometer disk
1
into the mounting frame. The engraving on the eyepiece micrometer disk
should face downward in the micrometer-mounting frame.
Screw the micrometer-mounting frame back into the eyepiece.

Fig. 12
}When the WHB10X-H (or WHB10X) eyepieces are used, an eyepiece
micrometer disk with a diameter of 20.4 mm and thickness of 1 mm
can be inserted in one of them using the 20.4RH reticle holders
3
(2-
piece set).
When the reticle holders are used, the field number becomes 19.6.
1. Place an eyepiece micrometer disk
4
in one of the reticle holders
3
so
that the engraving on the eyepiece micrometer disk faces downward.
2. Screw the reticle holder
3
containing the eyepiece micrometer disk
4
into the bottom of the eyepiece.
At the end of screwing, turn the reticle holder by hooking your nail on its
notch
5
to screw it all the way in.
3. To provide the other eyepiece with the same field number, screw in the
other reticle holder, without eyepiece micrometer disk, into the bottom of
the other eyepiece.
