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. Focusing

Place an object on the stage and x it with the slide holders.

Rotating the revolving head, switch magnication to the 4x objective.

Move the object to x its thickest part exactly under the objective.

Rotate the focusing knob to raise the stage until the objective is close to the specimen; keep check- ing 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 magnications; though, slight refocusing might be required. Selecting the objective We recommend that you start your observations with the lowest power objective; it helps to select a segment for the detailed research. Once the segment is selected, you should center its image in the microscope’s eld of view. This operation should be performed as precisely as possible, otherwise the required segment might fail to appear in the eld of view of the higher power objectives.

The microscope is designed for use in macroclimatic conditions with temperate or frigid climate, in the laboratories at temperatures from 10 to 35 °C (50 to 95 °F) and the relative air humidity up to 80% at 25 °C (77 °F).

The room should be free from dust, acid or alkali vapors, evaporations of other active substances.

The microscope should be used in the room protected from shocks or vibrations.

High temperatures and humidity may cause formation of mold or moisture condensation on the optical and mechanical parts of the microscope, which can negatively aect its operation.

When not in use the microscope should be covered with a special case.
