5. Connect the power cable to the power connector (13) of the microscope and a
free power outlet.
5. Observation
Turn on the microscope using the power switch (15).
Now, look through the eyepieces (1) of the binocular viewing and change the spa-
cing between the eyepieces so that you get a round, clear field of view. The defini-
tion 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.
6. 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.

optional accessories.
Hold the mounted objective (3) firmly with one hand and use a small flathead screw-

the desired interchangeable objective on the holder and screw it on with the slotted
screw as well.

Note:
The eyepieces of this stereo microscope can be replaced. Depending on the
model, additional eyepieces are included or can be purchased as optional accesso-

Use a small Phillips screwdriver to unscrew the cross screws on the two eyepiece
holders. Remove the eyepieces from the holders and insert others. Screw them on
with the cross screws as well.
9. 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 (17). Install the fuse holder and plug again.
