Compound Microscope

• Compound microscopes can be found in most biology and science classrooms. They are electrically operated and use light to enhance the image of a cell. They will have multiple lenses for viewing.
  

Dissecting Microscope

• Dissecting microscopes are also known as stereo microscopes. They have low magnification and are also light powered. These microscopes can view objects larger than what a compound microscope is able to handle, in three dimensions.
  

SEM

• A Scanning Electron Microscope uses electrons instead of light to create an image. These microscopes produce three-dimensional images with high resolution and magnification. They also have a larger depth of focus.
  

TEM

• Transmission Electron Microscopes use electrons instead of light to create an image. The material prepared must be very thin. The beams of electrons that pass through it give the viewer high magnification and resolution. These give two-dimensional images.
  

A compound lab microscope is generally intended for the following:
examination of prepared glass slides of: Organic Tissues organic fluids cells of plants and animals
The are used extensively in clinics to examine urine for the presence of gout or bacteria. Or to examine other body fluids.
Specimens need to be prepared on glass slides and sealed with a "glass cover slip". Prepared slides can be order from many different sources over the internet. Try searching "prepared specimen slides" or "prepared microscope slides" or use www.Microscope.com
A compound scope is not effective for examining things like insect structures, or any "solid" objects which light cannot pass through. For such research a "stereoscope" is required. The stereoscope directs light from above like a spot light.

The knob you are talking about is called the x-axis control knob. It does not directly affect the focus. What affects the focus is the slight manipulation of the stage and or slide while you are adjusting the x-axis control knob. It only takes the slightest pressure to throw the focus off very far. Theoretically you could completely remove the specimen holder and move the slide around with your fingers.
The specimen holder may need to be replaced but without further more detailed knowledge of the mechanical problem I cannot instruct further.

Open the clip, remove slide, replace slide, close the clip.

I had the same problem but the Geosafari Know it All is made by Educational Insights. I went to their website and sent an email asking if they might have the manual. Within a few hours they had sent me an email with the instruction manual attached in PDF form.
