ENGLISH

Thank you for purchasing the Celestron LCD Digital Microscope II with a 3.5" monitor. Your microscope is a precision optical instrument, made of the highest quality materials to ensure durability and long life. It is designed to give you a lifetime of enjoyment with a minimal amount of maintenance.

Before attempting to use your microscope, please read through the instructions to familiarize yourself with its functions and operations. Refer to the microscope diagrams to locate the parts discussed in this manual. If you run into any problems, see the trouble shooting section later in this manual.

This microscope provides high powers from 40x up to 400x (up to 1600x with digital zoom), ideally suited for examining specimen slides of all kinds. You will view specimens or objects on the LCD monitor instead of through an eyepiece. Specimens are easier to see on the LCD screen compared to a traditional microscope eyepiece. It's also easier to share the view with others. Best of all, you can take snapshots or short videos with the built-in digital camera.

SETTING UP YOUR MICROSCOPE

1. Remove the carrying case from the shipping box.
2. Unzip the case, and carefully remove the microscope and other parts and set them on a flat surface.
3. Insert the cylindrical plug on the end of the AC adapter into the socket on the back of the microscope (Figure 1) and then connect the plug end of the AC adapter into a proper power outlet as shown in Figure 2.

Note: The AC Adapter's plug is interchangeable for use around the world. You can choose among a USA-, UK-, or EU-style plug.

A. To change the plug, push down and hold the small button release (circled in Figure 3). Grasp the plug prongs with your free hand and rotate the plug head counter clockwise 90° to release. Reverse the procedure with your chosen plug head. When the new plug head is secured in place, you will hear a click.

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. You'll need 4 AA 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. After the batteries are installed, close the battery door. Battery life will typically be three hours.

ILLUMINATION

CELESTRON Navigation Buttons Select Button Menu Button Fig. 5

Proper illumination is key to ensure a quality image.

Your digital microscope is equipped both a TOP and BOTTOM adjustable illuminator. Each illuminator has an adjustment wheel located on either side of the base (see Figure 6).

The LCD Digital Microscope II is designed to work with specimens on slides. You will use the BOTTOM illuminator the most. It works by shining light up through the hole in the stage and through a specimen slide.

The TOP illuminator can be used with the BOTTOM illuminator when a slide specimen is thicker than normal. The lowest power for the LCD Digital Microscope II is 40x. Although it is not ideal, 40x can be used for viewing 3D objects, like coins or paper.

Digital Light Adjustment

The LCD Digital Microscope adjusts to the light digitally through the EV (Exposure Value) adjustment, similar to a digital camera.

Press and hold the MENU button to access the SETTINGS menu. Scroll to the EXPOSURE tab and press SELECT. In the EXPOSURE window, adjust the EXPOSURE UP (brighter) or DOWN (darker) using the NAVIGATION buttons (see Figure 7).

Tip: Viewing a specimen that is very dark in color decreases the amount of light that can shine through it from the BOTTOM illuminator. To correct this, you will need to increase the exposure setting by adjusting the illuminators to their highest settings.

Viewing a Specimen

Your digital microscope is equipped with a mechanical stage with adjustment knobs and a self-adjusting lever-action holding clamp (see Figure 8 below).

1. Use the thumb arm on the self-adjusting lever action holding clamp to open the clamp.
2. Place a specimen slide (3" x 1" / 76.2 x 25.4mm size) inside the holder and release the clamping arm, securing the slide in place.
3. Use the stage adjustment knobs to position the specimen over the opening in the stage. The rear stage adjustment knob moves the Y-axis (forward and backward), while the front stage adjustment knob moves the X-axis (side to side).

Note: A vernier scale on both axes allows the exact marking and replication of an object in the field of view.

Stage Adjustment Knob - Rear Stage Adjustment Knob - Rear Self-Adjusting Lever Action Holding Clamp Fig. 8

1. Use the objective nosepiece to rotate the objective lenses until the 4x objective lens is directly over the specimen and clicks into place. Always start with the lowest power objective-4x with this microscope, which gives you 40x power-and work your way up to higher powers. At 40x power, you will have the widest field of view and the brightest image.
2. Look at the LCD screen while turning the focus knob until the specimen comes into view. You may need to adjust the stage adjustment knobs (See Figure 8 above) to center the specimen.
3. With the 4x objective lens, you can vary the power anywhere from 40x to 160x by using the digital zoom. To do this, use the navigation buttons on the LCD. Press UP once and the zoom will adjust to 2x. Each additional press of the button will adjust the zoom by 1x, until it is at 4x. If you press UP again from 4x, it will go back to 1x. Press DOWN (from 1x) and the zoom will adjust to 4x, then 3x, 2x and back to 1x.
4. To view in higher powers, rotate the objective nosepiece to the 10x or 40x objective. You will need to refocus after this change.

Tip: When changing objective lenses, lower the stage to ensure there is no contact between any objective lens and the stage surface, which may result damage.

Using Filters

To change the filter settings, rotate the filter wheel (see Figure 9 below). The filter wheel choices are as follows:

Color: Red, Green, Blue

Clear: 1mm, 3mm and 6mm apertures.

Color filters work well with bright transparent specimens. The different diameter apertures (1mm, 3mm, 6mm) can help focus light on a section of a specimen, providing a more detailed image.

TROUBLE SHOOTING

If the image quality does not look right or there is no image, try the following:

1. Make sure the AC adapter is plugged in to an AC power source and attached to the microscope securely and correctly.
2. Make sure you have the illuminators turned on with maximum brightness adjustment. (This is the normal position).
3. Make sure the objective lens you have chosen is set correctly and it has clicked in the right position.
4. Make sure that the filter wheel is set correctly at a click position so that the illuminated light comes up properly.
5. Make sure the specimen slide is correctly fit into the clamp on the mechanical stage and that it is properly centered.
6. If the stage is wobbly or erratic in movement, make sure all screws on the top and side of the stage are tight, especially the two very small screws to the left of the long stage knob (see Figure 8).

CARE, MAINTENANCE, AND WARRANTY

Your Celestron microscope 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 switch.
• Turn off the LCD monitor.
• Unplug the power cord.
  • Always place the plastic bag or dust cover over the microscope when not in use or when being stored.
• Store the microscope in a dry and clean place.
• Be very careful if using your microscope in direct sunlight to prevent damage to the microscope or your eyes.

- When moving your microscope, carry it by the "arm" with one 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 fingerprints off of optical surfaces, use a lens cleaning agent and lens tissue available at most photo outlets. When cleaning, do not rub in circles, as this may cause streaks and 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.
