Introduction
Thank you for purchasing The Professor. This compound microscope is
specifically designed to have all the components of an adult microscope,
but have the simplicity for elementary users to view microscopic
specimens and objects under our easy to view, high-quality objective
lenses that will magnify 40-400 times. The Professor microscope uses
upper (incident) and lower (transmitted) ED lighting to keep your
specimen cool. Its compact size, rugged plastic construction, battery
power, and all-glass optics make The Professor ideal for use in the
classroom or in the field.

Microsco e Set-U Guide
The Professor compound microscope 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
microscope from the protective plastic bag and remove
the protective coverings from the objective lenses and the
eyepiece.
2. Place the microscope on a flat, firm surface.
3. Check the coarse focus knob on either side of the main
body support. The coarse focus knobs should turn easily.
NOTE: The stage should move freely up and down the main
body support when focusing. When you release the knob, the
stage should remain stationary, and not slide down the post on
its own.
4. Turn the microscope upside down and open the bottom
base plate.
5. Insert three (3) AA batteries in the +/- direction as
indicated on the microscope.
6. Insert the base plate into the notches and push to close.
7. When not in use, place the protective cover over the
microscope 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 compound
microscope:
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 ED lights are turned on by pushing the
light button to the right or left on the base.
NOTE: Switch the button right and the illuminator (lower) light will
turn on to view a standard microscope slide. Switch the button left
and the upper stage light will turn on to view macro (large) and
opaque specimens.
• Check to see if the objective lens is clicked into place.
• Turn the disc diaphragm, located underneath the stage, to
adjust the amount of light for viewing the specimen.
It is difficult to get the image in focus.
• Adjust the coarse focus knobs slowly.
• Check to see if there has been damage to the objective
lenses or eyepiece. If the lenses/eyepiece are dirty, use lens
paper and distilled water to rub gently to clean
NOTE: Never rub the lenses/eyepiece when it is dry. This can cause
static charge that will attract dirt.
