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 and holding the Power Button (see Figure
1) until the LED comes on below the on/off button and you see
"Celestron Digital Microscope" on the screen and hear a "beep"
sound. 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 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 changing
the EV function on the touch screen. The EV (exposure value)
function increases or decreases the brightness level by using the
(+) or (-) buttons on the screen.
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
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 first
time microscope users, it will take some time to get used to the
movements and shortly you will be able to center objects easily.
