Now, place a prepared slide (e.g. 11) under the
clips on the stage (4), directly under the objective.
When you take a look through the eyepiece, you
can see the magnified specimen. At this point, it
might still be a slightly fuzzy picture. The sharp-
ness is adjusted by slowly turning the focus knob
(2). You can now select a higher magnification
by turning the objective turret and selecting a
different objective.
In doing so, note that the sharpness of the picture
must be adjusted again for the higher magnifica-
tion. Also, the higher the magnification, the more
light you will need for good illumination of the
picture.
TIP: Avoid positioning the mirror so that it is ex-
posed to direct sunlight, since it can cause a glare,
which won't allow you to get a clear picture.
How do I make my own specimens?
Take the object that you want to observe and place
it on a glass slide. Then, add a few drops of dis-
tilled water on the object using a pipette. Now,
place a cover slip vertically at the edge of the drop
of water, so that the water runs along the edge of
the cover slip. Then, slowly lower the cover slip
over the water drops.
Note:
The included glue "gum media" (20b) is used to
make permanent prepared specimens. Use this in
place of the distilled water. If you want to keep the
object in place on the slide permanently, use the
gum media.
Electric Illumination
To use the electric light source (6), you need two
AA batteries (1.5 V), which are installed in the
base of the microscope (7). Remove the rubber
base (8) on the microscope and insert the batter-
ies according to the displayed +/- information. Re-
attach the rubber base to the microscope.
You can turn on the light
by rotating it in the di-
rection of the stage (4).

Take a look through the
eyepiece and adjust the

ness. Now you can ob-
serve in the same way
as described in point
1.3.
The bulbs for the electric light can be replaced.
One replacement bulb (16) is included. When you
use another bulb, make sure to pay attention to
the maximum wattage, which is displayed on the
lamp body.
TIP: The higher the magnification used, the more
light is required for a good illumination of the
picture. Therefore, always start your experiments
with one of the lower magnifications.
Projector
The included micro-projector (15) is ideal for
looking at a specimen with multiple people at the
same time. To use the projector, you absolutely
must use the electric illuminator. This way, you
can show your results to your friends and family.
