Select a suitable stool so that when looking into the eyepiece, your back is straight and your neck is bent at the nape.1. Lower the body tube by turning the course focus knob until the 10x or 16mm objective reaches the downward stop.2. Look through the eyepiece and adjust the mirror to the position which provides the brightest and the most evenly illuminated field of vision which is the circular area seen in the eyepiece. Raise the condenser until its top lens at the same level as the stage. Place the slide on the stage and fasten it using the stage clips.3. Position the specimen area of the slide over the center of the stage aperture.4. Looking through the eyepiece, raise the coarse focus knob until the image appears. Focus as sharply as possible.
