3. Observation

Turn on the microscope using the power switch (15).

Now, look through the eyepieces (1) of the binocular viewing and change the

spacing between the eyepieces so that you get a round, clear field of view. The

definition is adjusted by slowly turning the focusing wheel (11).

If you have to observe a very large or very small object, you can adjust the

microscope. Loosen the holding screw on the side and move appropriately

the microscope head on its guidance. If you have found the correct position

(distance of 22 cm from the object), tighten the holding screw again.

4. Diopter adjustment

Turn the left diopter adjustment ring (2) on the left eyepiece to the central

position (silver marking). Shut your left eye and look with the right eye through

the right eyepiece. Now focus with the focusing wheel (11), focus correctly for

your right eye. Now, look with your left eye through the left eyepiece. If the

image isn't sharp, adjust the focus for your left eye by turning the diopter

adjustment ring. Now, the microscope is correctly adjusted.

5. Exchange of the fuse

Switch off the microscope and pull out the plug of the power outlet. Grip with

a small screwdriver under the lug of the fuse holder (14) and pull it carefully

forward. Take out the fuse and change it into a new one. Install the fuse holder

and plug again.

6. Care and maintenance

Cleaning the lenses: Sweep the lens with a lens tissue or soft fabric immersed

with a small amount of alcohol (e.g. isopropanol).

Cleaning the painted parts: The dust on the painted parts can be removed by

cleaning cloth. For the grease spots, the gauze immersed slightly with aviation

gasoline is recommended. Do not use organic solvents such as alcohol, ether

or other thinner etc. for cleaning the painted parts or plastic components.

Your microscope is a high-quality optical instrument. Avoid disassembling the

microscope. Improper disassembling affects the high utility of the microscope.

Moreover, the warranty expires.Cover the microscope with the dust protective

cover and place it there, where it is dry and dust-free. We suggest the storage

of all objectives and eyepieces in a closed container with drying agent.
