General Warnings

Choking hazard — This product contains small parts that could be
swallowed by children. This poses a choking hazard.
Risk of electric shock — This device contains electronic components
that operate via a power source (batteries). Only use the device as
described in the manual, otherwise you run the risk of an electric shock.
Risk of fire/explosion — Do not expose the device to high temperatures.
Use only the recommended batteries. Do not short-circuit the device or
batteries, or throw them into a fire. Excessive heat or improper handling
could trigger a short-circuit, a fire or an explosion.
Risk of chemical burn — Make sure you insert the batteries correctly.
Empty or damaged batteries could cause burns if they come into contact
with the skin. If necessary, wear adequate gloves for protection.
Leaking battery acid can lead to chemical burns. Avoid contact of
battery acid with skin, eyes and mucous membranes. In the event of
contact, rinse the affected region immediately with a plenty of water
and seek medical attention.
Use only the recommended batteries. Always replace weak or empty
batteries with a new, complete set of batteries at full capacity. Do not
use batteries from different brands, types or with different capacities.
Remove the batteries from the unit if it is not to be used for a long
period of time, or if the batteries are empty!
Never recharge normal, non-rechargeable batteries. This could lead to
explosion during the charging process.
Rechargeable batteries are only to be charged under adult supervision.
Rechargeable batteries are to be removed from the toy before being
charged
The terminals must not be short-circuited.
Do not disassemble the device. In the event of a defect, please contact your dealer. The dealer will contact the Service Centre and can send the DE
device in to be repaired, if necessary.
Tools with sharp edges are often used when working with this device.
Because there is a risk of injury from such tools, store this device
and all tools and accessories in a location that is out of the reach of
children.

1. What is a microscope?
A microscope contains two lens systems: the eyepiece and the objective.
We’re presenting these systems as one lens each so that the concept
is easier to understand. In reality, however, the eyepiece (1) and the
objective in the turret (3) are made up of multiple lenses.
The lower lens (objective) produces a magnified image of the prepared
specimen. The picture, which you can’t see, is magnified once more by
the second lens (eyepiece, 1), which you can see as the ‘microscope
picture’.

2. Assembly and location
Before you start, choose an ideal location for using your microscope. It’s
important that you choose a spot with enough light for normal observation.
Furthermore, it is recommended that you place the microscope on
a stable surface, because a shaky surface will not lead to satisfactory
results.

3. Normal observation

For normal observation, place the microscope in a bright location (near
a window or desk lamp, for example).
Turn the focus knob (2) to the upper stop, and set the objective turret (3)
to the lowest magnification.
Now, turn on the light using the switch on the microscope base. You’ll find
further tips about the light source in the next section. Now, place a prepared
slide under the clips on the stage (4), directly under the objective
(1). When you take a look through the eyepiece, you can see the magnified
specimen. At this point, you still might see a slightly fuzzy picture.
Adjust the image sharpness by slowly turning the focus knob (2). You
can now select a higher magnification by turning the objective turret and
selecting a different objective.

When you do 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. The
wheel with pinhole apertures (9) below the microscope stage (4) will
help you in viewing very bright or clear-sighted preparations. Turn the
wheel (9) till the best contrast is achieved.

4. Observation (electronic light source)

Remove and insert batteries
For observation with the electronic light source (6) you need to insert
3 AA batteries 1.5 V, in the battery compartment (8) on the base of the
microscope (7). The battery compartment is opened using a Phillips
screwdriver. Insert the batteries with the correct polarity (+/- indication).
Put the battery cover first into the small opening so that the lid fits perfectly.
Now you can tighten the screw.
The lighting is switched on when you turn the switch on the microscope base.
Now you can observe in the same way as described in the previous section.

TIP: The higher the magnification you use the more light is required for
a good illumination of the picture. Therefore, always start your experiments
with a low magnification.

5. Condition and prepare viewed objects
This microscope features transmitted light, so that transparent specimens
can be examined.
If opaque specimens are being examined, the light from below goes
through the specimen, lens and eyepiece to the eye and is magnified en
route (direct light principle).
Some small water organisms, plant parts and animal components are
transparent by nature, but many others require pretreatment — that is,
you need to make a thinnest possible slice of the object by hand cutting
or using a microtome, and then examine this sample.
