Turn the On/Off Switch (14) "On" and adjust the brightness to the level you want.
Viewing a Specimen
Your instrument is provided with a mechanical stage with a stage holder clamp and directional knobs.
1.
Use the clamp lever to open the clamping arm of the stage holder clamp (9).
2.
Place a specimen slide (3" size) inside the holder and gently close the clamping arm against the slide
3.
Use the stage movement knobs (see bottom right of Figure 2b) to position the specimen over the opening in the stage (4). The top
stage movement knob moves the X axis (forward and backward) whereas the bottom stage movement knob moves the Y axis (side
to side). Note: A vernier scale on both axes allows the exact marking and replication of an object in the field of view that the user
may want to come back to.
Tip: To position the specimen directly under the objective lens, close the opening on the illuminator by turning it counterclockwise until
it is almost completely closed. You should see a small beam of light projected onto the specimen slide. Now simply use the stage
movement knobs (2b) to move the specimen directly inside the beam of light.
To achieve the best focus with your microscope, not only can you make adjustments with the coarse and fine focus knobs, but you can
also adjust the focus of each eyepiece (diopter adjustment (17) individually (your eyes are slightly different from each other) as well as
the interpupillary distance (distance between the center of your eyes). To achieve the sharpest focus – see Figure 2c and:
move your head side to side.
8.
Now read the number off of the eyepiece sliding plate scale. This is your interpupillary distance.
9.
Depending on your individual eyes, you may need to make slight adjustments to the right and left eyepieces for the most
comfortable viewing. Move the diopter up or down until you have the specimen slide in sharp and comfortable focus.
10. You have started with the 4x objective (which is the lowest power) and work your way up to higher powers.
11. Look through the eyepiece while turning the coarse focus knob (7) until the specimen comes into view. You may
need to adjust the stage knobs (Figure 2b) slightly to center the specimen in the field of view. Warning: When
focusing, be careful not to raise the specimen stage so high that the specimen slide touches the objective lens.
Not only can you break your slide but you may scratch the objective lens.
12. Finally, adjust the fine focus knob (13) until you reach the sharpest focus for your eye.

4.
First rotate each eyepiece diopter clockwise so that they are all the
way down.
5.
Change the distance between the eyepieces by sliding the eyepiece
slide plate in or out horizontally. To adjust the slide plate, grasp
the knurled portion on each side of the plate. Do not hold the
eyepieces to adjust the interpupillary distance.
6.
With the 4x objective lens focus with one eye using the coarse and
fine focus knobs.
7.
Adjust the eyepiece side plate until the whole field of view can be
observed through both eyes at the same time without having to
