Microsco e Set-U Guide
The Professor Stereo can be set up in a matter of minutes. To
get the most out of this amazing teaching tool, follow these
step-by-step directions:
1. After unpacking the box, remove The Professor
Stereo from the protective plastic bag and remove the
protective coverings from the lenses on the head and
the eyepieces.
2. Place the microscope base on a flat, firm surface and
place the stage plate on the base.
NOTE: The reversible black and white stage plate provides
appropriate contrast with the object being viewed.
3. Check the coarse focus knob on either side of the
main support post. The coarse focus knob should turn
easily.
NOTE: The head should move freely up and down the post
when focusing. When you release the knob, the head should
remain stationary, and not slide down the post on its own.
4. Turn the stereoscope upside down and open the
bottom base plate.
5. Insert two (2) new AA batteries in the +/- direction as
indicated on the stereoscope.
6. Insert the base plate into the notches and push to
close.
7. When not in use, place the protective cover over the
stereoscope to protect it from dust.

Troubleshooting
This section provides many useful tips on how to solve common
problems while setting up or using the The Professor Stereo:
I can’t see an image. I only see a partial image.
• Check to see if you need new AA batteries.
• Check to see if the LED lights are turned on by pushing the
red button on the base.
It is difficult to get the image in focus.
• Adjust the coarse focus knobs slowly.
• Rotate the eyepieces slowly until you see one focused image.
• Check to see if there has been damage to the objective lens
or eyepieces. If the lens/eyepieces are dirty, use lens paper
and distilled water to rub gently to clean
NOTE: Never rub the lens/eyepieces when it is dry. This can cause
static charge that will attract dirt.
