The lenses are screwed into the lens revolving unit in such a way that when you turn
the revolving unit, the next lens for stronger magnification moves into position.
Please make sure that you do not touch the lenses with your fingers and that no dust
enters the apertures. For lenses which are marked "OIL", you must use an immersion
oil with the lowest level of inherent fluorescence.

The condenser is already permanently fitted in the device. The height can be
adjusted using the focus dial.

head can be rotated by 180 degrees, for example. Then the gently retighten the
adjusting screw. Please make sure that you do not touch the lenses with your fingers
and that no dust enters the apertures.

OBE 111 microscope, only one eyepiece available on this). Remove the plastic
protective caps and insert both eyepieces. Please make sure that you do not touch
the lenses with your fingers and that no dust enters the apertures.
