Battery Operation — You can use your
microscope without AC power if you
choose. This gives you the freedom to
operate the microscope outdoors or
indoors anywhere you please. The battery operation
requires 4AA batteries (user supplied). Open the battery
door on the bottom of the microscope and insert the
batteries according to the battery polarity shown in the
battery compartment (Figure 4). After the batteries are
installed close the battery door. Battery life will typically
be three hours.

FIGURE 6
Before looking at specimens you must turn the LCD on, turn
on the proper illumination, and understand how to use the
mechanical stage and then you are ready to begin viewing.
Remove the protective film from the LCD screen.
LCD Module — This digital microscope is different than
traditional microscopes — instead of using eyepieces to look
at a specimen in a traditional microscope, the LCD monitor
replaces the eyepieces so you can look at the specimen on the
screen by yourself or share the views with others. To begin to
view specimens with your microscope, you will have to turn the
LCD monitor on by pushing the Power Button (see Figure 1) and
you see “Celestron Digital Microscope” on the screen. That is
basically all you need to do to use the LCD screen for viewing
specimens. The touch screen functions on the LCD Module
are mainly used for taking images (snapshots and video) and

value) function increases or decreases the brightness level by
using the (+) or (-) buttons on the screen.
performing other functions and will be discussed later in
this manual.
Illumination — To get the sharpest and best views, the proper
illumination (lighting) must be chosen:
1. To turn the illuminator(s) on, see Figures 5 & 6 and turn the
switches as shown for each.
2. The top illuminator (Figure 1) was designed to be used at low
power (4x objective) as higher power objective lenses (10x,
20x & 40x) will block some of the light. If you need to use
high power to observe solid objects, use a bright secondary
light (desk lamp, etc.) for directed illumination.
3. The bottom illuminator (Figure 1) is used mainly for specimen
slides where the light shines up through the hole in the stage
through the slide.
4. Having both illuminators on at the same time can provide
enough light for thick and irregular specimens.
Adjusting the Lighting — Specimens of different size, thickness,
and color variations will require different levels of illumination.
Normally you adjust the brightness by turning the switches
shown in Figure 5 & 6. Another way to adjust brightness is by
When viewing a specimen that is not transparent or dark in color,
you may need to increase the amount of light to resolve certain
features or details. This is best done by simply increasing the
brightness of the illuminator by rotating the brightness control
dial all the way to its highest setting.
Optimum lighting will be found by experimenting with
adjustments as each specimen may require slightly different
illumination as well as the same specimens viewed under
different powers.
Viewing a Specimen — Your instrument is provided with a
FIGURE 7
mechanical stage with a stage holder clamp and directional
knobs — see Figure 7.
1. Use the clamp lever to open the clamping arm of the stage
holder clamp.
2. Place a specimen slide (1” x 3”/25.4 mm x 76.2 mm size) inside
the holder and gently close the clamping arm against the slide.
3. Use the stage movement knobs to position the specimen
over the opening in the stage. The rear stage movement knob
moves the X axis (forward and backward) whereas the front
stage movement knob moves the Y axis (side to side). For rst
time microscope users, it will take some time to get used to the
movements and shortly you will be able to center objects easily.
4
Note: A vernier scale on both axes allows the exact marking
and replication of an object in the field of view that the user
may want to come back to.
4. Use the objective nosepiece (Figure 1) to rotate the objective
lenses (Figure 1) until the 4x objective lens is directly over
the specimen. Always start with the lowest power objective
(4x with this microscope) which gives you 40 power and work
your way up to higher powers. At 40 power you will have the
widest field of view and the brightest image.
5. Look at the LCD screen while turning the focus knob (Figures
1 & 7) until the specimen comes into view. You may need to
adjust the stage movement knobs (Figure 7) slightly to center
the specimen in the field of view. The larger focus knob is the
coarse focus and the smaller knob is for fine (exact) focusing.
6. With the 4x objective lens, you can also vary the power
anywhere from 40x to 160x by using the digital zoom.
7. For higher powers, you will need to rotate the objective
nosepiece to the 10x or 20x and to the 40x objective for the
maximum power. You will have to refocus when changing
the power of the objective lenses. While using any of these
objective lenses you also can increase power by using the
digital zoom. Note that using a higher power objective lens
will yield sharper images versus a lower power objective lens
and digital zoom for the same magnification.
Using Filters & the Diaphragm — Normally most viewing or
imaging will be done without colored filters and before using the
microscope check to make sure no filters are in the optical path.
However, to bring out different levels of detail, experiment with
changing the color of the back lighting of the specimen especially
for very bright transparent specimens. To change the lighting
color, rotate the wheel (Figure 8) to the desired color – Red (R),
Green (G), Blue (B). Each color is centered when you hear/feel the
faint click stop. You may need to refocus by adjusting the focus
knob (Figure 1) slightly for best viewing. You should experiment
with each of the colors to see the results.
Diaphragm — within the wheel are holes with three different
diameters, (1) 1 mm, (3) 3 mm, (6) 6 mm which limit the amount
FIGURE 9
8. Your microscope includes a 60x objective lens packed
separately. The 60x objective allows you the maximum
power available. When specimen detail requires extreme
power, you can install the 60x objective lens by replacing any
existing objective lens. Turn the knurled ring at the top of the
objective lens you want to replace counterclockwise until it
comes out. Then, install the 60x objective lens by turning it
clockwise until tight.
9. To use the digital zoom, you touch the screen icons on the
right side of the screen to increase or decrease the power
from 1x to 4x.
Note: When changing objective lenses, lower the stage
to its lowest position so you will not hit anything during
the rotation. Also, at the higher powers, be careful when
raising the stage close to the objective lens so that the
objective does not hit the slide specimen (or other object) and
cause damage.

of light passing through to the specimen. These holes are part of
the diaphragm which allows you to change the hole opening size
to maximize the contrast, brightness, etc.
The default setting is the (6) for the 6 mm hole which should be
used for most viewing. You can look under the stage (see Figure
9) to make sure the proper setting you wish is actually
being used.
Rotating the LCD Screen — You can rotate the viewing position
of the LCD screen 180° – 90° to the right and 90° to the left. You
can view any position you choose along the 180° rotation. This
function allows you to share the view with others without actually
moving the complete microscope. To move the LCD screen, hold
the top of the arm (see Figure 1) with one hand and then hold
the LCD module with the other and move it to the position you
desire.
You can adjust the tension of the rotation of the monitor by
tightening/loosening the adjustment screws as shown in Figure
1. It is best to have the tension somewhat tight so the monitor is
rigid. Turn the LCD screen on and you are now ready to use
your microscope for viewing and if any problems check the
trouble shooting section.
AV/TV Cable — To view specimens or images on a larger format
screen, connect the AV/TV cable in the receptable (see Figure1)
on one end and the other end into the socket on the monitor (if
your monitor has a socket for this purpose).

care, MaIntenance, and warrantY
Your Celestron accessory is a precision optical instrument and
should be treated with care at all times. Follow these care and
maintenance suggestions and your microscope will need very
little maintenance throughout its lifetime.
• When you are done using your microscope, remove any
specimens left on the stage.
• Turn off the illuminator switches.
• Turn off the LCD monitor — push the on/off button until you
see “Shutting Power Off”.
• Unplug the power cord.
• Always place the plastic bag or dust cover over the
microscope when not in use or when being stored to help
keep it clean.
• Store the microscope in a dry and clean place.
• Be very careful if using your microscope in direct sun light to
prevent damage to the microscope or your eyes.
• When moving your microscope, carry it by the “arm” with one
at a click position so that the illuminated light comes up
properly — the normal position is the 6 position (6 mm hole)
for most applications.
5. Make sure the specimen slide is correctly fit into the clamp
on the mechanical stage and properly centered.
6. Make sure the SD Card is inserted properly.
If icon does not display, then remove and insert again.

hand and not by the focuser knob, LCD monitor, etc. Then,
put your other hand under the base for support.
• Clean the outside surfaces (metal and plastics) with a moist
cloth.
• Always unplug any cords before cleaning.
• Never clean optical surfaces with cloth or paper towels as
they can scratch optical surfaces easily.
• Blow off dust with a camel’s hair brush or an air blower from
optical surfaces.
• To clean ngerprints off of optical surfaces, use a lens
cleaning agent and lens tissue available at most photo outlets
and when cleaning do not rub in circles as this may cause
sleeks or scratches to occur.
• Never disassemble or clean internal optical surfaces. This
should be done by qualified technicians at the factory or
other authorized repair facilities.
• When handling glass specimen slides, use care as the edges
can be sharp.
