Location
Before you start, choose an ideal location for using your
microscope. It is important that you have enough light
available, such as from a window or desk lamp.
Simple Observation
Place the object to be observed (for example, a rock) in
the middle of the microscope stage (5). When possible, it
is best to fix the object to be observed in place with the
stage clips (6).
Now, take a look through the binocular eye lens (1) and
change the distance of the eyepiece (3) so that you see a
circular, clear image.
Adjust the sharpness of the image by slowly turning the
focus knob (7).
Illumination
To illuminate objects to be observed, remove both eyepiec-
es (3) from the eyepiece supports (1) and turn the entire
microscope over. In the base of the microscope there is a
battery compartment (9). Push the clamp closure (10) and
open the battery compartment by pulling the cover open
diagonally.
Place the two AA batteries in the compartment so that the
flat minus poles (-) press against the spring terminal and
the plus poles (+) are touching the flat contact sheets.
Close the battery compartment with the cover and turn the
microscope around again. Place the eyepieces back on.
You can now turn on the light (4) with the on/off switch (8)
on the base of the microscope.
