3. Normal observation

For normal observation, place the microscope in a bright location (near a window or desk lamp, for

example). Remove the microscope from the package and tilt the microscope arm (9) so that it's in a

comfortable viewing position for you.

Turn the focus knob (2) to the upper stop, and set the objective turret (3) to the lowest magnification.

Now, take a look through the eyepiece and adjust the mirror (5) so that you see a uniform, bright

circle of light. Or, you can use the electronic light source (6). You'll find further tips about the light

source in the next section. Now, place a prepared slide (11) under the clips on the stage (4), directly

under the objective. When you take a look through the eyepiece, you can see the magnified speci-

men. At this point, you still might see a slightly fuzzy picture. Adjust the image sharpness by slowly

turning the focus knob (2) until the picture appears sharp and clear. You can now select a higher

magnification by turning the objective turret and selecting a different objective.

When you do so, note that the sharpness of the picture must be adjusted again for the higher mag-

nification. Also, the higher the magnification, the more light you will need for good illumination of the

picture.

TIP: Avoid positioning the mirror so that it is exposed to direct sunlight, since it can cause a glare,

which won't allow you to get a clear picture.

4. Observation (electronic light source)

To use the electronic light source (6), you need to install two 1.5-volt batteries in the base of the mi-

croscope (7). Remove the rubber base (8) on the microscope and insert the batteries according to

the displayed +/- information. Reattach the rubber base to the microscope.

You can turn on the light by rotating it in the direction of the stage (4). Take a look through the eye-

piece and adjust the light so that you get optimal picture brightness. Now you can observe in the

same way as described in the previous section.

The bulbs for the electronic light can be replaced. One replacement bulb (16) is included. When you

use another bulb, make sure to pay attention to the maximum wattage, which is displayed on the lamp

body.

TIP: The higher the magnification you use, the more light is required for a good illumination of the

picture. Therefore, always start your experiments with a low magnification.

Projector

The included micro-projector (15) is ideal for looking at a specimen with multiple people at the same

time. To use the projector, you also have to use the electronic light source (6). This way, you can

show your results to your friends and family. Unscrew the eyepiece (1) from the microscope and

place the micro-projector on the open eyepiece support so that the matte screen is pointing behind

you. Adjust the light so that the matte screen is lit up brightly.

You can adjust the focus of the prepared slide image using the focus knob (2). Make sure to swivel

the microscope arm (9) back into an upright position so that you can comfortably observe the speci-

men. In a dark room, it is also possible to project the microscope picture on a white wall. To do this,

remove the matte screen. Swivel the tripod so that the upper edge of the projector is horizontal. Keep

in mind that the image brightness is reduced and the picture will be darker if the projector is far away

from the wall.
