4. Place the object to be observed on the bottom
viewing panel, in the the center of the crosshairs
of the viewing panel. (Note that the side with the
coverslip faces up. Do not place it backwards.)
3. Adjust the microscope lift knob, so that the lens barrel
is at a relatively suitable height, easy to place the object
of observation.
5. Rotate the focus knob, observe the screen display, and slowly adjust
to the best viewing (Adjust the viewing height and focal length to
achieve different magnifications of viewing.)
