NOTICE
Using eyepieces and objectives
When using a specific eyepiece or objective, you will get the individual magnification of an object be-
ing observed. The magnification is imprinted on the eyepiece and objective with a large number (e.g.
10x for 10-fold magnification, 4 for 4-fold magnification).
1. Move the object plate downwards completely by turning the focus wheel.
2. Insert a slide and place it in the middle under the objective.
3. Set an objective with lowest magnification below the object plate.
4. Insert an eyepiece with lowest magnification in the eyepiece holder.
5. Turn on the device and the illumination.
6. Look through the eyepiece and move the object plate upwards by turning the focus wheel until a
sharp image is visible.
NOTICE
Avoid damages to the specimen!
Only turn the focus wheel until it stopps to avoid damages to the specimen throughout collision with
the objective.
1. If neccessary, adjust the image sharpness by turning the fine focus adjustment.
