To work with this microscope, sharp and pointed aids are being used. Please take care that this micro-
scope and its accessories are stored at a place out of reach of children. Let children only work with this
microscope under an adult's supervision! Keep packing material (plastic bags etc.) away from children!

3. General/Location
Before you set up the microscope, you must choose a suitable
location.
First you must make sure that your microscope is on a stable
and solid surface.
4. Electric illumination
It works, by plugging the connection cable into the micro-
scope socket (19) and plugging the AC adapter into the mains
socket. The switch at the rear of the microscope must be
switched on.
HINT for the rechargeable battery:
Your microscope is fitted with one built-in rechargeable batte-
ry. A fully charged battery allows ca. 48 hours of observation.
Before using the microscope for the first time the rechargeable
battery should be charged for 16 hours. Please charge it by
connecting the microscope socket (19) with the included AC
adapter and plugging the AC adapter into mains socket.
5. Observation
You begin each observation with the lowest magnification
(eyepiece 10x and objective 4x). So, the object to be viewed
can easy be centred and properly focussed. The higher the
CAUTION!
magnification the more light is required for good image quality.
For applications with the 100x lens, it is recommended that
examinations are done only with oil immersion.
Begin with a simple observation. Turn the objective revolver (4)
onto the smallest magnification and insert the 10x eyepiece.
Now place a preparation directly under the objective on the
microscope table. Move the preparation on the table with the
two adjusting screws (14 and 15).
Now look through the eyepiece (1) and turn the coarse ad-
justment (12) carefully until the image becomes visible. The
optimal sharpness is achieved by the fine adjustment (13).
Make sure that you never overtighten the fine adjust-
ment.
6. Condenser
Use the condenser height adjustment knob (10) to properly
bundle the light for your objekt.
7. Iris diaphragm
An iris diaphragm (8) is available if you want better image qua-
lity. This makes it possible to change perspective depth. The
smaller the aperture the greater the perspective depth. Howe-
ver, image brightness is also reduced. You can compensate
for this by adjusting the brightness using the regulator (16).
8. Filter holder
Push the filter holder (9) forwards and then insert the blue filter
if you wish to use it. The filter holder can then be pushed back
again. This filter is used to show natural colours.
9. Oil immersion
The immersion oil is only necessary for the 100x objective.
Give one drop of immersion oil onto the upper condenser lens.
With the slide clamp (6), fix your prepared slide on the mecha-
nical desk. Using the condenser height adjustment knob (10),
move up the condenser (7) carefully, until the slide touches
the immersion oil. Focus the preparation with the 100x objec-
tive and the fine focuser as good as possible. Now turn the
objective revolver a little bit to the side and give one drop of
immersion oil onto the preparation's covering glass.
Turn back the objective revolver. The objective must dive into
the oil! Now the preparation can be focused. Don't forget to
clean objective and preparation with alcohol after observing.
10. Care and cleaning
1. Avoid disassembling the microscope!
Because of being a precise optical instrument, do not
disassemble the microscope casually. That may cause se-
rious damage to its performance. Do not disassemble the
objectives.
2. Avoid contamination!
You should make sure that dust or moisture do not come
in contact with your microscope. Avoid putting fingerprints
on any optical surfaces! If dust or dirt nevertheless have
gotten onto your microscope, or the accessories, remove it
as described below.
3. Cleaning non-optical parts
Disconnect the plug from mains socket before cleaning
