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

(10).
screw at the battery
compartment
with a small Philips
screwdriver and re-
move the cover. Place the batteries in the com-
partment 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
called the object or specimen, by the way.) You
can use each lamp on its own. There is a selec-
tion switch for this (12). It has two numbers: I
and II. If you select the ...

For transparent objects (transmitted-light ob-
jects), number I is best. In order to observe firm,
non-transparent objects (direct-light objects),
Loosen the select number II.
cover When do I use the color filters?
The color filter wheel (27) is located below the
microscope stage (7). They help you when you
are observing very bright or clear specimens.
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).
How do I adjust my microscope correctly?
Each observation starts with the lowest mag-
nification.
I, the light only
comes from be-
low (transmitted
light).
II, the light only
comes from
above (reflected
light).
Adjust the microscope

stage (7) so that it goes
all the way down to the
lowest position (11).
Then, turn the objective
