3. Unpacking and assembly 

The microscope is packed in a molded styro-
foam container.  

 

Take the container out of the carton remove 
the tape and carefully lift the top half off the 
container. Be careful not to let the optical 
items (objectives and eyepieces) drop down. 

 

To avoid condensation on the optical compo-
nents, leave the microscope in the original pack-
ing to allow it to adjust to room temperature. 

 

Using both hands (one around the pillar and 
one around the base), lift the microscope from 
the container and put it on a stable desk. 

 

The objectives will be found within individual 
protective vials. Install the objectives into the 
microscope nosepiece from the lowest 
magnification to the highest, in a clockwise 
direction from the rear.  

 

Put the head onto the top of the stand and 
tighten the head-lock-screw. Insert the eye-
piece into the tube. 

 

4. Operation 

4.1 General information 

 

Set the microscope on a level table. 

 

Place the object to be observed in the center 
of the object plate. Use the clips to fasten it 
into place. Make certain that the specimen is 
centered over the opening in the stage. 

 

Connect the mains cable to the net and turn 
on the switch to get the object illuminated. 

 

Make certain that the specimen is centered 
over the opening in the stage.  

 

Adjust the aperture of the iris diaphragm to 
get the background brightness suitable for a 
high contrast image. 

 

Rotate the nosepiece until the objective with 
the lowest magnification is pointed at the 
specimen. There is a definite “click” when 
each objective is lined up properly. 

NOTE: 

It is best to begin with the lowest power 

objective. This is important to reveal general 
structural details with the largest field of view 
first. Than you may increase the magnification 
as needed to reveal small details. To determine 
the magnification at which you are viewing a 
specimen, multiply the power of the eyepiece by 
the power of the objective. 

 

Adjust the coarse-focusing-knob which 
moves the stage up until the specimen is fo-
cused. Be careful that the objective does not 
make contact with the slide at any time. This 
may cause damage to the objective and/or 
crack your slide. 

 

Adjust the fine-focusing-knob to get the im-
age more sharp and more clear. 

 

Colour filters may be inserted into the filter 
holder for definition of specimen parts. Swing 
the filter holder out and insert colour filters. 

 

Use the knobs of the mechanical stage to 
move the slide side-, back- and forwards. 
The vernier provides accurate location of the 
specimen area. 

 

Always turn off the light immediately after use. 

 

Be careful not to spill any liquids on the mi-
croscope. 

 

Do not mishandle or impose unnecessary 
force on the microscope. 

 

Do not wipe the optics with your hands. 

 

Do not attempt to service the microscope 
yourself. 

 

4.2  Changing the fuse 

 

Turn off the power switch and unplug the 
mains plug. 

 

Unscrew the fuse holder on the back of the 
stand base with a screwdriver. 

 

Replace the fuse and reinsert the holder in 
its socket. 

 

5. Storage, cleaning, disposal 

 

Keep the microscope in a clean, dry and 
dust free place. 

 

When not in use always cover the micro-
scope with the dust cover. 

 

Do not expose it to temperatures below 0°C 
and above 40°C and a max. relative humid-
ity of over 85%. 

 

Always unplug the mains plug before clean-
ing or maintenance. 

 

Do not clean the unit with volatile solvents or 
abrasive cleaners. 

 

Do not disassemble objective or eyepieces 
to attempt to clean them. 

 

Use a soft linen cloth and some ethanol to 
clean the microscope.  

 

Use a soft lens tissue to clean the optics. 

 

The packaging should be disposed of at 
local recycling points. 

 

Should you need to 
dispose of the equip-
ment itself, never throw 
it away in normal do-
mestic waste. Local 
regulations for the dis-
posal of electrical 
equipment will apply.
