First take the container out of the carton, and lay the container
on its side. Open the container carefully and don’t let the
optical items drop down, avoiding them being damaged.
Check carefully to ensure the arm and accessories are well.
Second put the monocular head or binocular head onto the top
of the arm, and tighten the head-lock-screw. Install the
objective into the microscope nosepiece from the lowest
magnification to the highest, in a clockwise direction from
the rear. Insert the eyepiece into the eyepiece tube.
2-1 Angle of observation
Loosen the head-lock-screw and turn the monocular head or
binocular head to a comfortable position for observation.
Then lock the head-lock-screw.
2-2 Set the specimen slide
Place a specimen to be studied on a glass slide, and fix it by
the slide-holders of the mechanical stage. Turn the stage
knob to make certain that the specimen is centered over the
stage opening.
2-3 Set illumination
For the microscope only with mirror, turn the mirror to get
the field of view illuminated.
For the microscope with built-in electrical illuminator, insert
the plug of the main cable into the power socket and turn on
the power switch to get the specimen illuminated. Then turn
the brightness-adjustment-
knob slowly to get the brightness suitable.
2-4 Adjust focus
Loosen the limit-stop-knob, and adjust the coarse-focusing-
knob to bring the slide into focus. Then lock the limit-stop-
knob to avoid impact between the objective and slide. Adjust
the fine focusing knob
