by turning the focusing knob. Subsequently, the auto focus function (standardly
activated) will adjust the image to the maximum focus quality automatically.
The focusing area is determined by the colored focusing frame (standardly activated),
which can be put to any place on the screen by a left click on the mouse.
Focusing done.
The tension of the focusing knob can be adjusted by turning both knobs in opposite
directions at the same time.
Magnification:
Choose the right magnification by turning the zoom wheel.
When changing the magnification level, it might be necessary to adjust the light
intensity (turn dimmer) and/or the working distance (turn focusing knob) afterwards.

0.7x, 1.0x, 2.0x, 3.0x, 4.0x, 4.5x
Please don't try to turn the zoom wheel any further when set to 0.7x or 4.5x
