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 magnification.
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
NOTE! Before initial operation, the foil used for
protecting the battery from discharging must be
pulled out of the battery compartment.
Locate the mirror/light on the base of the micro-
scope. Flip the mirror/light with the light facing up
and press the button to power on the light. This mi-
croscope is equipped with an incandescent light that
illuminates the specimen from below.
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.
Battery change
1. Remove the safety screw from the cover.
2. Remove the battery cover.
3. Slide out the coin battery holder.
4. Install the CR2032 coin battery with the positive
(+) polarity facing down and the negative (-) po-

5. Replace the battery cover.
6. Screw in the safety screw back to the cover.

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.
Unscrew the eyepiece (1) from the microscope
and place the micro-projector on the open eye-
piece support so that the matt screen is point-
ing behind you. Adjust the light so that the matt
screen is lit up brightly.
