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

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.



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.

3.2 Dioptre adjustment (BE5 and TE5)



Look through the right-hand eyepiece with

your right eye and focus on the object.



Then look through the left-hand eyepiece

with your left eye. If the image is not well fo-

cussed, turn the dioptre adjustment ring (1)

until it is (see Fig. 1).

The dioptre adjustment ring (1) is marked with

dioptric values of ±5. The value to which the

scale marking (2) points corresponds to the

dioptric value for the user.



Set up the same value next time you use the

microscope as well.

3.3 Setting of interpupillary distance (BE5

and TE5)



Look through the eyepieces with both eyes

and turn the tubes around the axle until you

can see only one image field.

Point (1) indicates the interpupillary distance of

the user on the scale (2) (see Fig. 2).



Set up the same interpupillary distance next

time you use the microscope as well.

3.4 Adjustment of retaining attachment



You need to adjust the retaining attachment

(1) in order to fix the following problems: Dif-

ficulty turning the coarse focus adjustment

knob, slide slowly losing focus, sliding of ob-

ject stage (see Fig. 3).

Turning the knob for the retaining attachment in

the direction of the arrow secures the retaining

attachment. Turning in the opposite direction

loosens the focussing drive.

3.5 Changing the lamp



Turn off the power switch and unplug the

mains plug.



Unscrew the base plate and remove it.



Unplug the connector to the LED unit by

pressing on the connector socket (1) and

pulling out the plug (2) (see Fig. 3).



Undo two screws (3), swap the faulty LED

unit for a new one and then screw the mi-

croscope back together.
