SAFETY
Do not disassemble any parts of the microscope, except where noted in the instruction
manual.
In case of a problem with the microscope, contact The Microscope Store, LLC, at (877)
409-3556 or [email protected].
Do not touch the bulb while microscope is in use. The bulb is very hot. Allow bulb to
cool before replacing. To prevent fire, do not place combustibles near the bulb.
To avoid electric shock or damage to the instrument, unplug the microscope before
replacing the bulb. Use only the recommended halogen bulb. Wear gloves, or cover
the bulb with a protective sleeve. Do not touch the glass with bare skin.
Turn off and unplug the microscope before moving. Keep microscope on a level and
sturdy surface.
The microscope should be kept at temperatures between 0°C-40°C/32°F-104°F, with a
maximum humidity of 70 percent.
Do not place the microscope in direct sunlight or under direct indoor light. This
environment can influence the quality of the specimen imaging.
Avoid dust. When not in use, cover the microscope with a dust cover.

ASSEMBLY
*Use figure 1 (page 5) to aid in assembly.
1. Remove the main body of the microscope from the foam box and place it on a
working table.
2. Install the trinocular body on the base. Tighten the screw on the right of the base
to affix the body.
3. Insert the 10x eyepieces into the eyetubes.
4. Attach the four included objectives to the nosepiece in sequence from low
magnification to high magnification. Make sure the objectives are secure.

PREPARATION BEFORE USE
*Refer to Figure 1 on previous page
● Insert the trinocular viewing head (2) into the microscope arm (10) and lock up bolt (19)
per drawing.
● Attach the objectives (11) to the screw hole of nose piece (3) per big and small
gradation. Place eyepiece (1) into the eye tube (2).
● Plug the power cord into the microscope base (22) (Note: Voltage of power supply
must accord with the instrument.) The lamp will sparkle when you turn on the switch (21).
● Use the adjustment bolt to adjust the aperture diaphragm image in field center.
● Use the adjustment handle (17) to change the diameter of the aperture diaphragm.
● Turn the adjustment ring (8) to adjust the field diaphragm diameter.
● To adjust the brightness, use the lamp adjustment knob (18).
● Place the filter on the filter seat (7) and then replace to correct position.

OPERATION
*Refer to Figure 1 on page 5
1. Use the specimen clips (12) to secure a specimen to the mechanical stage specimen
in the clip (12) of mechanical stage (4), and then use the adjustment knob (5) to place the
specimen below the objective.
2. Use the movement lock ring (13) to move the condenser (27) up and down.
3. Use a middle magnification objective (11), such as 10x, for viewing. Use the coarse
adjustment knob (14) to focus the specimen image in the right side eyepiece. Use the fine
focus adjustment knob (15) to fine-tune the image. Turn the dioptric ring (9) in the left
eyepiece tube until the image is crisp.
4. Continue to use the fine focus adjustment knob (15) when you switch magnifications to
receive a clear specimen image.
5. Adjust the interpupillary distance (the distance between the eyes) by sliding the
eyepiece tubes left or right.
6. When using the 100x, raise the condenser (27) to the highest position, and then drop a
a slight bit of immersion oil on the surfaces of the objective itself and the slide and condenser.
Then view the specimen.
MAINTENANCE
1) When not in use:
a. Always cover the microscope with the dust cover.
b. Store in a dry place.
c. In humid or moist environments, it is advisable to store the microscope in a
waterproof container with a drying agent.
