Operation
Adjust the observation head
Loosen the lock-screw, turn the observation head to a comfortable position for observation, and then lock the
lock-screw.
Place the specimen on the stage
Lock the specimen slide on the mechanical stage using the slide holder. Ensure that the specimen is centred
over the stage opening by adjusting the coaxial knobs of the stage.
Lamp settings
The microscope is fitted with a power white LED illuminator. Before turning on the light, read the section
about electrical safety precautions. Insert the plug of the power supply into the jack on the rear and turn on
the ON/OFF switch. Turn the brightness adjustment knob to a brightness suitable for observation.
Adjust interpupillary distance (binocular models)
Hold the right and left side of the observation head with both hands and adjust the interpupillary distance by
turning the two parts until one circle of light can be seen, when looking down the microscope with both eyes.
Focus and diopter adjustment (binocular models)
Rotate the coarse focusing knob to bring the slide into focus using a low magnification objective. Adjust the
fine focusing knob to get the image sharp and clear while observing with your stronger eye, then turn the di-
optric adjustment ring on the opposite eyepiece until a sharp and clear image can be observed also with the
other eye. Turn the tension adjust knob to achieve a suitable focus tension without the specimen dropping out
of focus. When the image is in focus, turn the nosepiece to choose the objective you need.
Condenser adjustment
Hold the notched ring at the base of the condenser and rotate it up or down until you reach a clear and uni-
form sample illumination.

ROTATE IT
Set the numerical aperture
Adjust the aperture of the iris diaphragm to set the numerical aperture of the illuminator, thus controlling im-
age contrast and resolution.
