How to Use the Projection Device

1) Twist the eyepiece counterclockwise and gently pull up to

remove it. Insert the viewer head over the focusing tube.

2) Face the viewer head toward a white wall or a piece of white

paper.

3) Turn out the room lights and close any curtains. For best results

the room should be dark.

4) Turn on the electric illuminator and place a prepared slide on the

stage.

5) Try a distance of 1 to 1.5 meters (3 to 4 feet) from the wall or

paper.

6) Adjust the illuminator lamp so that the image is as bright as

possible.

7) Carefully adjust the focus until you see a sharp image. You may

have to readjust the illuminator position.

8) You should now see a clear projected image. If you use a higher

magnification you will have to refocus the microscope.

How to Use the Drawing Device

You can observe the image on the unit's projection screen, or you can

project an enlarged image onto a white surface.

1) Make sure that the plastic viewing screen is in place in the slot

on the top of the viewing hood.

2) Adjust the focus and illuminator until you see a clear image on

the screen.

3) To see an enlarged image, remove the plastic viewing screen

from its slot.

4) Make sure that the microscope is in the upright position.

5) Place a piece of white paper horizontally in front of the base of

the microscope.

6) Darken the room and adjust the angle of the viewer hood mirror

until you see the image projected on the white paper. Adjust the

focus and illuminator lamp position for the best result.

IMPORTANT SUGGESTIONS: When you are using the drawing

device or the projection device you must be in a darkened room.

You will see the brightest views in a very dark room. Make sure that

the batteries are fresh and all lenses and mirrors are clean. Before

studying your slides in the dark, give your eyes a few minutes to

adjust.

When using the projection device you may get some "light spill."

This is unwanted light that comes directly from the illuminator or

bounces off of reflective surfaces. This unwanted light can

overpower the projected image, making it very hard to see. If light

spill is affecting your projected image you might try placing your

hand in front of the illuminator to block this extra light.
