How do I use my microscope?
Before you assemble your microscope, make
sure that the table, desk or whatever surface
that you want to place it on is stable, and does
not wobble.
How do I operate the electric LED
illumination?
In the base of the mi-
croscope there is a
battery compartment
(14).

screw at the battery
compartment
with a small Philips
screwdriver and re-
move the cover.
Place the 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.
The first lamp shines onto the specimen from
below and the second from above. (The thing
that you want to observe with the microscope is

can use each lamp on its own. There is a selec-

Here, you can choose from various colors. This
helps you better recognize the components of
colorless or transparent objects (e.g. grains of
starch, protozoa).
I, the light only
comes from be-
low (transmitted
light).
II, the light only
comes from
above (reflected
light).
