When Wearing Eyeglasses
Use with the eye shades in the normal, folded-down position. This will
prevent the eyeglasses from contacting and scratching the eyepieces.
When Not Wearing Eyeglasses
Extend the folded eye shades in the direction of the arrow for efficient
use of the eyeshades by preventing extraneous light from entering
between the eyepieces and eyes.

}Prepare one eyepiece micrometer disk (diameter 20.4 mm, thickness 1
mm) and two 20.4-RH reticle holders (available as 2-piece set).
The field number becomes 19.6 when the reticle holders are used.
When the tilting observation tube is used, the field number is fixed at
18 and does not change.
}If your eye is poor in eyesight and cannot focus the micrometer, use
eyeglasses to correct your vision.
1. Loosen the eyepiece clamping screws @ using a small, flat-blade
screwdriver and remove both eyepieces. When the tilting observation
tube is used, remove only the right eyepiece.
2. Hold the micrometer disk ² with the side with indications facing down
and place it into a reticle holder ³.
#Be careful not to leave dirt on the micrometer disk, as it will be
noticeable during observation.
3. Screw the reticle holder ³ containing the micrometer disk ² into the
bottom of an eyepiece.
Be sure to screw in all the way by hooking your nail into the notch |
on the holder at the end.
4. Screw the other reticle holder, alone, into the other eyepiece in order to
align the field number.
5. Attach the eyepieces again and tighten the clamping screws @.
