container. Be careful not to let the optical
items (objectives and eyepieces) drop down.
•
To avoid condensation on the optical com-
ponents, leave the microscope in the original
packing to allow it to adjust to room tem-
perature.
•
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 microscope is fully assembled except for
the eye-shields. Position them over the eye-
pieces for viewing comfort and to block out any
ambient light. In addition, the object plate must
be inserted into the stage opening in the base.

3.1 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.
•
Connect the mains adaptor, and switch on
the illumination.
Alternatively, the microscope can also be oper-
ated without being connected to the mains.
•
When using transmitted light illumination
replace black and white plate with the glass
plate.
•
On the toggle switch position I is for trans-
mitted light and position II is for top-light.
•
Adjust the interpupillary distance between
the eyepieces by grasping the two prism-
housings with both hands and moving them
until one circle of light can be seen.
•
Focus the object by turning the side knobs.
•
It might be necessary to loosen the lock-
screw and raise or lower the entire stereo
head-bracket until the outline of the object is
found in the field of view.
•
Be sure to tighten the lock-screw to fix the
height of the stereo head on the pillar.
•
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. 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.
•
Do not dispose of the battery in the regular
household garbage. Follow the local regula-
tions (In Germany: BattG; EU: 2006/66/EG).
