Viewing a Specimen
Your instrument is provided with a fixed, simple stage with holding clips to guide the positioning of the slide holder.
1. Place a specimen slide - 1" x 3" size (25mm x 76mm) into the slide holder. Do this by gently placing the specimen slide under the
small guides of the slide holder (Figure 6). Then, push the slide all the way into the cutout in the slide holder.
2. The slide holder with slide inserted will be placed onto the stage with the arrow on the slide holder pointed forward.
Inside the stage (Figures 7 & 8) are two small holding clips under which the slide holder is to be inserted.
3. Push the slide holder in until you begin to see the specimen (remember to start at the lowest power). You can examine the specimen
by moving the slide holder back and forth slowly and moving it slightly to the left or right.
4. For slides that have the specimen off to one side you may not be able to see the entire specimen and in these cases you can then
remove the slide from the slide holder and rotate the slide 180° and try again.
5. Manually moving the slide holder may seem difficult at first but after experimenting it becomes quite easy to use.

Once the slide is in place you will be ready to start viewing by setting the power.
6. Use the power knob (in the center of Figure 9) to rotate the objective lenses until the 4x
dot is lined up near the indicator – it will click when positioned correctly. Always start
with the lowest power objective (4x with this microscope) which gives you 24 power and
work your way up to higher powers. At 24 power you will have the widest field of view
and the brightest image.
7. Look at the LCD screen while turning the focus control (Figure 9) until the specimen
comes into view. You may need to position the slide specimen as discussed above so the
image is in the field of view.
8. With the 4x objective lens, you can also vary the power anywhere from 24x to 192x by
using the digital zoom of the LCD module. Use the direction keys (Up/Down) on the
LCD module to use the digital zoom. On the left of the screen will be an icon indicating
what digital zoom setting you are at. Note: Digital zoom is best up to 4x.
9. For higher powers, you will need to rotate the power knob to the 10x objective position
for medium power and to the 40x objective for the maximum power. You will have to
refocus when changing the power of the objective lenses. While using either of the 10x
or 40x lenses you also can increase power by using the digital zoom.
Note: At maximum powers the images may not be as sharp and dark. Your best views will be at the lower powers.
You can take snapshots or a short video with your microscope using the built-in digital camera. With the internal storage memory, you
do not need to use a PC or any other devices to do imaging. Transferring of images to your PC for saving and or printing them is easy
and will be discussed later in this manual.
Note: If you are going to take images, do not connect the USB cable to your PC or damages could occur to the equipment. The
USB cable is not used at all for taking images!

General Settings

Before setting up the snapshot or video menus you need to make some general setups first. You can enter the general settings from the
Snapshot Mode, Video Mode, or Time Mode (all three with icons showing in the top right of the LCD screen). You navigate the
different modes by pressing the Esc key.
You begin by pressing the Menu key and this will have "Capture" or "Video Output" highlighted at the top left of the screen. Then press
the Right direction key which will then show "Setup" highlighted. Your choices are below and you navigate to each selection by using
the Up/Down keys.
1. Format – press OK to enter, choose to Cancel or Execute, and then press OK to set.
