•
Never look at the sources of bright light or laser through the microscope: it will cause DAMAGE
TO YOUR EYES!
•
Do not disassemble the microscope or camera on your own.
•
Keep the microscope and camera away from condensation; do not use them in rainy weather.
•
Keep the microscope away from shock or excessive pressure.
•
Do not overtighten the locking screws.
•
Keep the microscope and camera away from hostile environment, home and car heaters, incan-
descent lamps or open flame.
•
When cleaning any optical surfaces, first blow dust or loose particles off the surface or wipe them
off with a soft brush. Then wipe the lens with a soft clean tissue slightly moistened with spirits or
ether.
•
Never touch the optical surfaces with your fingers.
•
Unpack the microscope.
•
Make sure all the parts are present.
•
Move the stage to the lowermost position using the focusing knob.
•
Press the ON/OFF button located on the back side of the microscope base next to the power cord to turn
the microscope on.
•
Place an object on the stage and fix it with the slide holders.
•
Rotating the revolving head, switch magnification to the 4x objective.
•
Move the object to fix its thickest part exactly under the objective.
•
Rotate the focusing knob to raise the stage until the objective is close to the specimen; keep checking
the distance between the objective and the object to avoid their contact.
•
Look through the eyepiece installed in the monocular head and lower the stage slowly rotating the
focusing knob until you see the object image.
Such adjustment protects the frontal lens from contacting the object when you use objectives of other
magnifications; though, slight refocusing might be required.
We recommend that you start your observations with the lowest power objective; it helps to select a seg-
ment for the detailed research. Once the segment is selected, you should center its image in the micro-
scope's field of view. This operation should be performed as precisely as possible, otherwise the required
segment might fail to appear in the field of view of the higher power objectives.
