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
(power supply and/or 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.
• 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 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 placed on the stage
(4). 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). Remove the microscope from the package and tilt the microscope arm (9) so that it’s in a
comfortable viewing position for you.
Turn the focus knob (2) to the upper stop, and set the objective turret (3) to the lowest magnification.
Now, take a look through the eyepiece and adjust the mirror (5) so that you see a uniform, bright
circle of light. Or, you can use the electronic light source (6). You’ll find further tips about the light
source in the next section. Now, place a prepared slide (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, you still might see a slightly fuzzy picture. Adjust the image sharpness by slowly
turning the focus knob (2) until the picture appears sharp and clear. 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.
TIP: Avoid positioning the mirror so that it is exposed to direct sunlight, since it can cause a glare,
which won’t allow you to get a clear picture.
4. Observation (electronic light source)
To use the electronic light source (6), you need to install two 1.5-volt batteries in the base of the microscope (7). Remove the rubber base (8) on the microscope and insert the batteries according to
the displayed +/- information. Reattach the rubber base to the microscope.
You can turn on the light by rotating it in the direction of the stage (4). Take a look through the eyepiece and adjust the light so that you get optimal picture brightness. Now you can observe in the
same way as described in the previous section.
The bulbs for the electronic 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 you use, the more light is required for a good illumination of the
picture. Therefore, always start your experiments with a low magnification.
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 also have to use the electronic light source (6). 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 eyepiece support so that the matte screen is pointing behind
you. Adjust the light so that the matte screen is lit up brightly.
You can adjust the focus of the prepared slide image using the focus knob (2). Make sure to swivel
the microscope arm (9) back into an upright position so that you can comfortably observe the specimen. In a dark room, it is also possible to project the microscope picture on a white wall. To do this,
remove the matte screen. Swivel the tripod so that the upper edge of the projector is horizontal. Keep
in mind that the image brightness is reduced and the picture will be darker if the projector is far away
from the wall.

Notes on Cleaning
• Before cleaning the device, disconnect it from the power supply by removing the plug or batteries.
• Only use a dry cloth to clean the exterior of the device. To avoid damaging the electronics, do not use
any cleaning fluid.
• Protect the device from dust and moisture.
• The batteries should be removed from the unit if it has not been used for a long time.
Disposal
Dispose of the packaging materials properly, according to their type, such as paper or cardboard.
Contact your local waste-disposal service or environmental authority for information on the proper
disposal.
Do not dispose of electronic devices in the household garbage!
As per Directive 2002/96/EC of the European Parliament on waste electrical and electronic
equipment and its adaptation into German law, used electronic devices must be collected separately and recycled in an environmentally friendly manner.
Empty, old batteries must be disposed of at battery collection points by the consumer. You can find out
more information about the disposal of devices or batteries produced after 6 January 2006 from your
local waste-disposal service or environmental authority.
In accordance with the regulations concerning batteries and rechargeable batteries, disposing of
them in the normal household waste is explicitly forbidden. Please make sure to dispose of your
used batteries as required by law—at a local collection point or in the retail market. Disposal in domestic
waste violates the Battery Directive.
Batteries that contain toxins are marked with a sign and a chemical symbol.
1
