Clean the exterior of device with a dry cloth. Do not use cleaning fluids so as to avoid causing damage to electronic components.

Clean the lens (objective) only with the cloth supplied or some other soft lint-free cloth (e.g. micro-fibre). Do not use excessive pressure – this may scratch the lens.

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.

Empty batteries and accumulators must be disposed of separately. Information on disposing of all such equipment made after 01 June 2006 can be obtained from your local 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

Your Microscope

What is a Microscope?
The microscope is made of two lens systems: the eyepiece and the objective. We’re presenting these systems as one lens each, so that it‘s 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) magnifies the prepared specimen (e.g. 11), which leads to a magnified image of the specimen. The picture, which you can’t see, is magnified once more by the second lens (eyepiece, 1). Then, you can see the “microscope picture.”

Assembly and Location

Before you start, choose an ideal location for using your microscope. On the one hand, it‘s important there is enough light (normal observation). On the other hand, it’s important that you can quickly make the room dark when you want to (projector observation). Furthermore, I recommend that you place the microscope on a stable surface, since you won’t be able to get any satisfactory results on a shaky surface.

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.

The focus knob (2) is turned to the upper stop and the objective turret (3) is set to the lowest magnification.
Normal Observation

Now, take a look through the eyepiece and adjust the mirror (5) so that you get a uniformly bright circle of light. Or, you can use the lamp. You’ll find further tips about the lamp in the next chapter.

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 sharpness 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.
Normal Observation

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 exposed to direct sunlight, since it can cause a glare, which won’t allow you to get a clear picture.

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 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 point 1.3.

The bulbs for the electric light can be replaced. One replacement bulb (14) 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.
