2. Unpacking and assembly

The microscope is packed in a molded styro­foam container.

• Take the container out of the carton remove

the tape and carefully lift the top half off the

1

container. Be careful not to let the optical

-

y

c

items (objectives and eyepieces) drop down.

• To avoid condensation on the optical compo-

nents, leave the microscope in the original pack­ing 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 microscope is fully assembled except for the
eye-shields. Position them over the eyepieces 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. Operation

• 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 oper­ated without being connected to the mains.

• When using transmitted-light illumination

replace black and white plate with the glass
plate.

• Turn the objective to get the desired magnif ication.

• 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 prism­housings 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.

• To rotate the microscope head, loosen the

head lock screw.

• Always turn off the light immediately aft er 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 humid­ity 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 dis

pose of the equipment it­self, never throw it awa
in normal domesti
waste. Local regulations
for the disposal of electri­cal equipment will apply.

• Do not dispose of the battery in the regular

household garbage. Follow the local regula­tions (In Germany: BattG; EU: 2006/66/EG).
