II. Parts of the microscope
III. Assembly and set up
Carefully remove the microscope from the box and set it on a sturdy, flat surface.
Remove the plastic covers from the eyepiece holders on the microscope's head, then
place eyepieces into the holders. You may choose at this time to insert the eyepiece
adapter into the trinocular camera port on the top of the microscope and place either a
third eyepiece into it or mount an eyepiece camera (not included). Locate the power
adapter and attach it to the microscope, then plug it in. Turn the microscope on by
pressing the power button on the back of the base.
IV. Using the microscope
Turn the microscope on and use the illumination intensity control wheel to set the lamp
on the lowest brightness setting.

Clip a slide into the slide holder on the stage. Use the X-Y translational control knobs on
the right side of the stage to move the stage front to back or the slide holder left to right
to center the specimen over the bulb.
Move the binocular eyepieces closer together or further apart until you see one image
when you look through them. Adjust the bulb brightness to a comfortable intensity with
the dimmer wheel.
Always start with the lowest power objective lens, in this case the 4X objective, centered
over the stage. Look through the eyepieces and bring the image into focus by slowly
turning the larger coarse adjustment focus knob to bring the stage closer to the
objective. Once an image forms, switch to the blue fine adjustment focus knob to
fine-tune for clarity or to see the various layers of the specimen you are examining. You
may also use the diopter adjustment control on the eyepiece holder at this time to
further fine-tune image clarity. Look at other parts of the slide by using the X-Y
translational control knobs to move the slide holder once the specimen is in focus.
Increase magnification by rotating the nosepiece clockwise to a higher magnification
objective, taking care not to strike the slide with the objective, as doing so may damage
the glass on the slide, the objective, or both. If you cannot move the objective into place
without making contact with the slide, use the coarse focus knob to move the stage
down and away to make room before changing magnification.
Adjust the focusing ring on the iris aperture diaphragm to change the resolution of the
image. The condenser can be manually moved closer to or farther from the stage by
rotating the metal knob.
For best results with the 100X objective, use the included immersion oil. Rotate the
nosepiece so that the 100X objective is near, but not on the specimen slide. Then place
a drop of the included immersion oil onto the cover slip. Slowly rotate the 100X objective
into place so that it comes into contact with the immersion oil. Adjust focus until your
specimen comes clearly into view. (Note: Immediately after use, always gently wipe the
oil off of the objective lens and the cover slip with lens paper moistened with a small
amount of ethyl or isopropyl alcohol. Do not use immersion oil with the 4X, 10X, or 40X
objectives.)

V. Mounting a camera attachment
Place the eyepiece adapter into the trinocular camera port on the top of the microscope
and mount an eyepiece camera (not included) directly on it. If you would like to use a
C-mount camera (not included), unscrew the top ring from the eyepiece adapter. You
can then use it as a 1X C-mount for the camera.
The parfocality between the eyepieces and the trinocular port has been preset before
shipment and should not need adjustment. If necessary, however, you can rotate the
parfocal ring in the eyepiece adapter to adjust the adapter height position and resulting
parfocality.
VI. Caring for your microscope
As with any quality instrument, your microscope should be stored in a cool, dry place.
Use the dust cover to protect the microscope when not in use. If necessary, clean the
lenses with a soft brush or compressed air to gently remove dust.
Avoid touching the optical surfaces directly and never disassemble the optical
components of the microscope. When not using eyepieces, use the plastic covers to
protect the eyepiece lens holders and ocular lens.
VII. Troubleshooting
If you have a problem, you may be able to correct it yourself. Here are some common
issues and easy solutions you can try before calling customer support for service.
