Usage:
1. Put binocular into bended arm’s seat, and tighten lock screw.
2. Screw objectives into nosepiece, from low-magnification to high-
magnification.
3. Put a specimen into the fastening unit on mechanical stage.
4. Turn on light.
5. Turn elevating knob to elevate condenser. And seeing diaphragm’s
image from eyepiece tube you swing handle to make the diaphragm’s
image coincide with aperture of using objective, at the same time you
should also adjust centering screw.
6. Insert a pair of eyepieces into the binocular eyepiece tube.
7. To focus (set objectives 10x on):
To observe by left eye, along with turning coarse focusing knob until a
image is seen, then turning fine focusing knob until the image is sharpness.
And now to adjust diopter ring of right eyepiece until the image appears
very clear, too.

8. Adjust interpupillary distance to meet you eyes, thus the specimen’s image
is clear in both of your eyes.
9. To meet special demand for magnification, you can turn the nosepiece and
select the needed objective.
10. To obtain a satisfactory image, please make the condenser up or down.
Turn brightness wheel if brightness is not enough.
11. Illuminative area on the specimen can be controlled by adjusting ring.
12. In order to look for the observed target, you may rotate adjusting knob.
13. When you use objective 100x to observe, put a little cedaroil on the
surface of the condenser and slide so as to keep full of cedaroil between
the condenser and the slide, also full of cedaroil between the objective and
the slide. (Clean the cedaroil with xylene after observation.)
14. Put filter in filter bench if you need.
15. As lock ring acts on, elevating height of the stage is limited at some
position that you expect to protect objective and slide from danger.
16. Turn the tension ring to adjust tension, but to protect the stage slides
down, please do not make tension too small.
Maintenance:
1. Keep the instrument in dry and cool place, and keep away from acid or
alkali. Put a dust cover over the instrument when it is not used.
2. Keep lenses clear, and wipe the lenses with soft brush if there is dust or
dirt on it.
3. To exchange a bulb loose the lock screw and open the lid to replace the
bulb.
4. To exchange a fuse when it is broken out, please screw the cover of fuse
box to replace it.
